Causes Of Hair Loss For Men And Women

Only those who suffer from hair loss can understand the feeling of discovering a new treatment, starting to use it full of hope, then having to put it together with the other 25 items on the “tried and true” list to begin with. from scratch again.

The point is that tackling the problem “blindly” is exhausting and very frustrating. There are numerous factors that can cause your hair to fall out, and without knowing the exact cause of the problem it is even more difficult to find the ideal treatment.

The first step, then, is for you to investigate some of the main suspects in male and female hair loss cases . We’ve rounded up 65 of them here – get to know each one better and collect the clues, so you could end up uncovering the real cause of your problem. Perhaps your find is a few altogether!

Some important points before you start :

• If you are one of those people who has just read a drug leaflet and you already think you can cope with the side effects, keep calm! Your case may not be as simple as it seems.
• That said, hair loss can actually be a first symptom to discover other diseases. So doing your research carefully and seriously can protect you from more serious problems in the future.
• Also, more than one cause may be contributing to your hair loss . If the baldness is genetic, for example, other causes could be accelerating its progress.
• Never use this article (or any other content you find on the Internet) as a basis for taking medicine on your own . We are going to repeat this several times throughout the text, but it never hurts to remember that your treatment should always be prescribed and controlled by a doctor.
• This list is not intended to exhaust all possible causes of hair loss, but rather to give an overview of the range of possible reasons for the problem. If you know of a possible suspect that is not listed here, feel free to investigate and let us know in the comments at the end of the article so we can include them in future reviews!

You can use the list below to click directly on the topic that interests you and start reading there, since it is a very long article and we do not always have time to read it in one go.

Hereditary causes

1- Male pattern baldness

• It occurs in man;
• There must be cases of baldness in the family;
• Begins to develop “recesses” (hair recedes from the birth line on the forehead) and thinning of the hair on the top of the head;
• The gradual advancement of this framework is observed over several months or years (hair loss did not start suddenly);
• You have no other significant complaints (no itching, pain, or swelling in your head);

If you observe these symptoms, it is very likely that you suffer from androgenic alopecia , the main cause of male pattern baldness in the world.

This problem has a genetic history (if your father, uncles or grandparents have baldness, the probability that you also suffer from it is great). It is caused by a hormone derived from male testosterone (called dihydrotestosterone or DHT) , which progressively reduces hair activities and makes the strands thinner and thinner. It even stops its growth completely.

The androgenic alopecia has no permanent cure , but there are several or ptions treatment. The finasteride , minoxidil and shampoos with ketoconazole are some of the most widely used, but there are other alternatives.

The hair transplant offers encouraging results in more severe cases, and hair prosthesis is a non – surgical alternative immediate effect also has good results, check the following article for more about androgenetic alopecia .

2- Female pattern baldness

Men are the most affected by androgenic alopecia, but this problem also causes hair loss in women. The difference is that instead of developing the classic pattern of male pattern baldness, women often have a more diffuse shape and the loss is distributed throughout the scalp . Also, the female version generally manifests later than in men (often only after menopause).

Not all treatment options for androgenic alopecia are ideal for women, but there are several alternatives and appropriate versions to combat it, check the following article for more on androgenic alopecia.

Nutritional problems

3- strict diets

Very restrictive diets (that prevent or reduce the consumption of certain foods) can cause serious nutritional deficiencies , and hair can be one of the first affected.

The body uses a series of substances (proteins, lipids, minerals, etc.) to keep our hair follicles active. These resources are also needed in other parts of the body, so if any of them are missing, the body prioritizes the most important organs and systems.

Hair is one of the last of the line: if there aren’t enough nutrients for everyone, it’s probably going to run out before it can be used by hair .

Therefore, beware of “magic” or overly radical diets. Your hair may end up paying the price. Read on to learn about some of the most common nutritional imbalances in hair loss cases, but we recommend that you take a look at these 19 tips for a Healthy Eating

4- Weight Loss

The hair loss associated with a great weight loss can have several explanations. One of them is that the weight loss may have been caused by a very radical diet , as we have just seen, or a frame of hyperthyroidism.

It can also be a case of telogen effluvium , a type of temporary hair loss that can occur when the body undergoes any major changes or impacts. In this case, the tendency is for the fall to stop when the body stabilizes with the new weight.

5- Lack of Proteins

As our hair is made of protein ( more specifically keratin ), it is possible that low levels of this protein in the diet can affect normal hair production.

This is not a common problem because our normal diet is generally high in protein, but it can occur in the case of diets that restrict certain foods, eating disorders (such as anorexia and bulimia) or malabsorption syndrome .

Vegetarians should also take into account that the quintessential sources of protein are of animal origin (meat, fish, chicken, eggs, dairy products), so they will need to compensate with other natural options if possible (such as soy, beans and lentils, for example).

Be careful with protein supplements. They tend to be designed for people who do vigorous physical activity, and are easy to find on the market, but excess protein in the body can cause problems like nausea, diarrhea, and kidney damage. It is best that you consume them only under medical supervision.

For the same reason, it is good that you also watch out for high protein diets (with a strong reduction in carbohydrates or other food groups). Consult a nutritionist before thinking about making a radical change in your diet.

6- Lack of Iron

Many people who have hair loss also have low iron levels . Science has yet to clearly establish what the relationship between the events is, but many experts have observed significant improvements in hair loss patients when iron levels are improved (and many doctors believe that you don’t have to be anemic to benefit of this type of measure).

When in doubt, it is best to take an iron supplement, right? Incorrect! Excess iron in the blood also causes serious problems , so any supplement intake should always be accompanied by a doctor.

If you think you may be deficient in iron (other symptoms are fatigue, depression, headaches, shortness of breath, and pale mucous membranes), you should first try to solve the problem with food. Red meat, beans, lentils, tofu, and spinach are some of the greatest natural sources of iron (and it is believed that when combined with vitamin C, iron absorption is even greater).

7- Lack of Group B Vitamins

The so-called B complex involves a number of vitamins:

• B1 (thiamine)
• B2 (Riboflavin)
• B3 (Niacin)
• B5 (pantothenic acid)
• B6 (pyridoxine)
• B7 (Biotin)
• B9 (folic acid)
• B12 (cobalamin)

They participate in the digestive process, muscle development and health in various parts of the body (liver, nerves, eyes, skin and hair), and help prevent iron deficiency (which can also be related to hair loss).

The B vitamins are found in dairy products, eggs, meat, liver, cereals, and vegetables . A varied diet provides the necessary levels, but some restrictive diets can cause vitamin deficiencies. B12, for example, is found primarily in animal products, so many vegetarians require supplements. For more information read our article on Vitamins Group B: All the SECRETS of the 8 different types

People who have had bariatric surgery or have other nutrient absorption problems can develop multiple vitamin deficiencies. If this is your case, consult your doctor and evaluate the need to consume a supplement or make changes in your diet to compensate.

Some of the most used supplements to strengthen hair and nails , such as Pantogar , have some type of vitamin from group B in their formula. It is believed that correcting the deficiency of these vitamins may be one of the secrets to their success.

8- Excess of vitamin A

Vitamin A is important for our vision and the health of the skin, immune system and other functions. But hypervitaminosis (excess vitamin in the body) can cause hair loss over time (in addition to other symptoms such as decreased appetite, dry skin, dizziness, headache, and liver damage).

It is extremely difficult to consume too much vitamin A from just the usual diet (unless you are an Eskimo, consuming large amounts of animal liver every day). Most current cases of hypervitaminosis A are associated with excessive intake of vitamin supplements and certain medications (such as retinoids, which are derived from vitamin A ).

One product that many people mix into shampoo to try to speed up hair growth, Monovin A, is a vitamin. It is a super concentrate for veterinary use. There is no evidence that it is absorbed through the scalp, but we are talking about a concentration of vitamin A that can be dangerous for humans. Read more about the Monovin A shampoo pump here .

9. Excess of vitamin C

When it comes to hair, vitamin C is often more of a villain than heroin. This vitamin helps to increase the absorption of iron in the body (essential substance for our health and for the proper growth of hair), but in excess it can increase the concentration of some fungi that aggravate the marks of dandruff and pityriasis (problems that can cause hair loss). Other possible complications include an increased risk of developing kidney stones, digestive problems, and increased acidity of the urine (which can cause irritation).

Excess vitamin C is even rarer than vitamin A, since our body can eliminate it quite easily. However, knowing that it has many positive effects, many people may go overboard and consume vitamin supplements in very high doses (more than 1,000 mg per day).

Regular consumption of fresh fruits and vegetables should be enough to provide all the vitamin C your body needs, without the risk of side effects. If you want more information, we leave you a ranking of the 50 foods with the most Vitamin C.

10- Excess of vitamin E

The vitamin E has a powerful antioxidant effect, protecting cells against the action of free radicals. It is believed that it can prevent or alleviate the symptoms of various diseases such as Alzheimer’s syndrome, cardiovascular disorders, and even certain types of cancer.

Despite all these benefits, excess vitamin E should also be avoided, as it is capable of “thinning the blood” (effect similar to aspirin) and impairing iron absorption (which is important for good health of the hair).

The natural sources of vitamin E ( vegetable oils , peanuts, almonds, eggs , butter and some vegetables) are frequent in our normal diet, so it is very difficult to overdo only through food. Again, the biggest danger is over-supplementation. No more than 15 mg per day is needed, and the dose above 250 mg is considered excessive and dangerous.

11- Lack or excess of Iodine

Iodine is an essential mineral for thyroid function. Its lack or excess can worsen cases of hypothyroidism or hyperthyroidism, and both problems are related to hair loss, so it is important to keep the levels balanced.

Iodine deficiency is very rare today. It is present in some foods we eat regularly (such as fish, shellfish, eggs, milk and liver), and it is also added to our table salt. Low iodine levels are often the result of very restrictive diets , and high levels often occur due to supplementation and excessive consumption of foods such as algae and crustaceans .

12- Lack or excess of Selenium

Selenium is essential for the growth of keratinocytes (cells that make up hair filaments), and it can also improve dandruff frames . It is found in cereals (wheat, rice and corn), fish and shellfish, liver, meat and poultry, but none of these sources is superior to the Brazil nut, which is very rich in selenium.

It’s even worth a word of warning: avoid consuming more than two or three nuts a day, as excess selenium can also cause your hair to fall out . Also be wary of supplements, which can drive rates well above the optimal level.

13- Lack or excess of Zinc

Zinc participates in the processing of proteins in our body and the synthesis of DNA, two important functions for the reproduction of cells in the hair follicle. It is also used in the production of thyroid hormones, and in some cases hypothyroidism treatment cannot resolve hair loss until zinc levels normalize.

Zinc is also important in testosterone production , but it appears to have some inhibitory effect on the conversion of this hormone to dihydrotestosterone, the version that is responsible for androgenic alopecia . That is, it is possible that those who suffer from classic baldness can also benefit from an improvement in the levels of zinc in their bodies.

Some natural sources of zinc are oysters, red meat, liver, eggs, nuts, shellfish, shrimp, and soy products. If you do not reach the recommended levels only through food, you can benefit from zinc supplements , but you need to be careful since excess can alter the absorption of other nutrients such as iron and copper, and end up worsening the loss hair related.

Damage to hair

14- Smoothing and Thermal Modeling with dryers, irons and curlers

It can often appear that your hair is falling out, when in fact it is breaking. The application of excessive heat with a hairdryer, flat irons , tongs and curlers, can damage the structure of the hairs , making them more brittle and prone to breakage.

The risk of damage is even higher when the hair is wet. Water particles, when in contact with a source of intense heat, can change their physical state (change from liquid to gas) very quickly. The process can cause “bubbles” in the hairs and weaken the cuticle ( outer layer that protects the hair ).

Ideally, you should always use the minimum heat possible : keep the iron or curling iron at lower temperatures and a safe distance from the dryer on the hair. Products that offer thermal protection can also help mitigate damage.

15- Very Hot Bathrooms

Many people love a hot bath, especially in the colder months. But if you are one of those people, it is good that you know that this can damage your hair. Hot water can also leave hairs dry and cuticles open (which means they are more fragile), and irritate the skin on the scalp .

When hair loss is associated with some type of infection (such as dandruff or psoriasis, for example), very hot water can make it worse and further accelerate hair loss. Check out our articles to learn how to effectively wash your hair and use the Co-washing technique to wash your hair .

16- Force excessive combing of hair

There are two things that many people find normal, but from today you should not accept more:

• Pain when detangling hair;
• Keep your neck tight to prevent your head from being pulled back while someone brushes or blows your hair.

Using excessive force when combing hair can put too much stress on the roots and cause traction alopecia – physical trauma suffered repeatedly that can cause hair to stop growing.

To detangle, you should ideally start at the ends, work your way to the middle, and finally, comb from the roots. Never pull the comb down hard (this only works to untangle a few strands and break the others!). If your hair is very tangled, apply an oil to help lubricate and loosen the hairs.

To blow-dry your hair, it’s best to remove most of the moisture before you start (to reduce the time your hair is tightened during the procedure) and work with small strands (which allow for more control and don’t require much strength to stretch).

17- Tight hairstyles

Tight ponytails, ballerina buns, and hairstyles with braids close to the scalp put a lot of strain on the hairs , which can cause them to pull out of the follicles. In the long term, you may suffer from traction alopecia.

Also be careful with the accessories you use to hold your hair, such as hair ties, clips, and buckles. In addition to tight-fitting designs increasing the stress on the hair, some can also damage the structure of the hairs, causing them to break. Preferably choose models made with fabric, without rubber bands or garters.

18- Very aggressive chemicals

The bleaches, dyes and relaxers chemical mess with the structure of the hair cuticle opening, in order to reach the cortex ( click here to understand how they work ). During the performance of these procedures, the hair is very exposed and fragile, and if not performed correctly, hair can be dull, porous, dry and brittle. To avoid this risk, always find a trusted professional and test a small section before applying the product to all of your hair.

It is worth mentioning the straighteners that use formaldehyde or Glutaral. None of them are authorized in Europe and several countries in the world, as they can cause serious damage to health.

Hair loss, burning eyes and irritation of the skin of the scalp, as well as the membranes of the nose and mouth, are minor problems: these substances have even been associated with the development of some types of cancer. Take care of the health of your hair and your life! It is not worth the risk.

Female hair loss

19- Menstrual Period

Some women tend to experience more pronounced hair loss during menstruation . This may have to do with both hormonal fluctuation in your period and blood loss (particularly if the flow is too intense), which can lead to a deficiency of iron (a mineral essential for hair growth).

If the case is mild, it may be that an increase in iron supply reduces hair loss. But if you notice severe conditions, it is best to speak with a doctor (gynecologist or endocrinologist) to assess if your hormone levels are within normal. Irregularities in the menstrual cycle can be a symptom of PCOS , which can also be related to hair loss.

20- Polycystic ovary syndrome

One of the characteristics of polycystic ovary syndrome is the production of androgenic hormones at higher than normal levels. Some of these hormones are associated with androgenic alopecia (which causes most cases of baldness ), and can promote hair loss.

Other common symptoms are acne , hirsutism (pronounced body hair development), weight gain, and menstrual irregularities . If you suspect this may be the case, seek out a gynecologist. Once the diagnosis is confirmed and the syndrome is treated, you should see an improvement in hair loss.

In some cases, PCOS can be associated with other problems such as diabetes, hypertension, hypothyroidism, psoriasis, and eating disorders. Since these conditions are also linked to hair loss, it’s worth investigating if any of them could be the actual cause of the problem.

21- Contraceptives

Birth control pills have different combinations of hormones to inhibit ovulation, and they can cause hair loss for a number of reasons.

In some people, this occurs in reaction to medication (as seen with other drugs). In other cases, it is the hormonal profile of the pill that affects the hair. It is believed that progesterone- predominant formulas can stimulate the development of androgenic alopecia if the person is already prone. Pills with a higher proportion of estrogens can have the opposite effect: they help protect against hair loss and stimulate hair growth. In this case, there may be hair loss when the pill is stopped.

You should discuss the decision to take birth control pills with your gynecologist and based on many other factors (never thinking only of hair). In some cases, the fall only occurs when treatment is started or stopped, and then resolves normally. If the problem is more persistent, it is worth consulting with your doctor and evaluating the possibility of changing the pill or taking other treatments.

An important warning: the combination of birth control and smoking can cause further hair loss, plus it also increases the risk of thrombosis and strokes.

22- Pregnancy

In most cases, pregnancy is very good for the hair ( hair loss is most common in the period after birth). Hormones during pregnancy are high and this tends to leave hair thicker and shinier, causing it to fall out less than normal. However, some women observe the opposite effect, losing more hair during pregnancy.

This can be both a response of the body to the changes caused by pregnancy and a manifestation of some other problem, such as some nutritional deficiencies. The pregnancy hormone (which is like a roller coaster) may interfere with the development of hypothyroidism or hyperthyroidism, conditions that can lead to brittleness and hair loss. The onset of gestational diabetes may also play a role in the problem.

Ideally, you should seek your doctor and eliminate suspicions. The specialist will guide you to treat any disease or make adjustments (including the use of supplements). If hair loss is not related to these factors, ideally you should wait and see if everything will return to normal after pregnancy and the puerperium (which usually happens in most cases).

23- Birth of a baby

A pregnancy is always a revolution in a woman’s body, and the body takes time to fully recover after delivery. It is quite common to experience hair loss in the six months after the baby is born . This is a normal reaction of the body to the hormonal fluctuation experienced during pregnancy and which begins to normalize.

What many women notice as hair loss after childbirth is actually hair that returns to normal (because during pregnancy, hair tends to be thicker and falls out less than normal). However, in some cases it may be the appearance of hypothyroidism and hyperthyroidism after childbirth, which can accentuate hair loss . Ask your doctor to clarify doubts and start a treatment if necessary.

The breastfeeding has nothing to do with the fall of the hair , but because the production of milk nutrients requires the body of the mother is vital that you adopt a rich and balanced diet to prevent nutritional deficiency (which can harm both the quality of the milk and the health of the mother, which can also cause hair loss).

24- Menopause

Women are believed to develop androgenic alopecia later than men because female hormones protect the follicles from the action of DHT (the hormone that causes baldness). As the production of these hormones is reduced by menopause, hairs can become more vulnerable to falling out.

The HRT can help prevent this effect, but it is an option you should consider with your doctor, who will weigh all factors related to your health (not only the loss of hair). Other alternatives are the various treatments available for female androgenic alopecia ( click here to learn more about them ).

Remedies and treatments

25- Anabolic

The anabolic steroids derived substances with functions similar to those of testosterone , hormone primary male. They can be prescribed to correct low levels of this hormone in the body, but many people use anabolic steroids to improve athletic performance and muscle growth.

Androgenic alopecia is caused exactly by a hormone derived from testosterone, called di-hitrotestosterone (or DHT). This means that if you have a predisposition to baldness, an anabolic can accelerate its appearance.

Truth be told, hair loss is the least of the problem when it comes to anabolic androgenic steroids. We are talking about substances that can cause liver damage, increase in blood pressure and cholesterol, increase the risk of heart problems, blood clots and even stimulate the growth of cancer cells.

Therefore, unless they are being used for medical advice to correct a hormonal imbalance, it is best to reconsider using anabolics. There are numerous options to promote physical performance and muscle mass that do not endanger your health or that of your hair.

26- Antibiotics

There are three main hypotheses about what causes some antibiotics to cause hair loss. The first , associates the reaction to the impact that almost any drug can cause in the body, or a reaction to one of the components of the medication.

In the second place, some antibiotics can Affect the red blood cells and reduces the levels of iron and some vitamins of group B . Since both substances are important for hair growth, reducing them can trigger hair loss.

The third hypothesis is that it would not be the antibiotic, but the same disease that the drug is fighting . As the body concentrates on defeating the “invading agent” and recovering, hair growth is no longer a priority.

In all three cases, the most important thing of all is to note that the hair loss will be temporary: as soon as the disease is cured and the drug is discontinued, your hair will return to normal. The biggest problem is antibiotics taken for long periods of time, if your treatment requires it, talk to your doctor to evaluate the possibility of changing the dose or type of antibiotic prescribed.

27- Anticoagulants

Anticoagulant drugs such as warfarin, heparin and acetylsalicylic acid (aspirin) are used to prevent the formation of blood clots in cases where there is a predisposition to develop them (family history of myocardial infarction, stroke, stroke and angina of chest among others).

This class of medications can negatively affect iron levels in the body, especially when taken for long periods of time, which could influence hair loss . Ideally, a doctor can see if there is a need to adjust your dietary supplements to correct iron levels. Or, if this is not the problem, consider changing the drug or dosage to try to mitigate the effects.

28- Anticonvulsants

They are used for the prevention and control of seizures, epilepsy, and bipolar disorder. Anti-seizure medications can have some side effects that affect the skin (redness, allergic reactions, itching, among many others).

Hair loss can arise associated with these reactions or due to other possible side effects of medications , such as the reduction of some important vitamins for hair (such is the case of group B). Discuss your situation with your doctor and make possible adjustments (both in diet and in medicine).

29- Antidepressants

Antidepressants are used to treat depression, obsessive-compulsive disorder, anxiety , eating disorders , sleep disorders , and other illnesses. They interfere with the processing of neurotransmitters, substances that participate in the communication of nerve impulses and regulate a series of aspects of our body, such as hunger, sleep, temperature and sexual activity.

Any interference in relation to these substances generates significant impacts on the body, and this shock could be the cause of hair loss. In some situations, the hairs may even change color or texture (get shiny, dark, or kinky, for example).

Hair loss associated with antidepressants is classified as telogen effluvium and is generally only temporary. In some cases, it occurs only during the body’s adaptation to the new substance, and resolves on its own after a few months. Other, more persistent situations can be resolved by substituting the drug (changing to a different brand or with other active ingredients) or adjusting the dose. Ideally, you should talk to your doctor about the options available for your treatment.

30- Antihypertensive

Some medications used to treat high blood pressure (such as beta-blockers) can also cause hair loss . However, since pressure can actually be the cause of the problem, we must first ensure that the disease is under control and only then suspect the drug. In these cases, discuss with your doctor the options to adapt the treatment.

Interestingly, one of the most commonly used substances to combat hair loss , minoxidil , was initially used only as a drug for high blood pressure (known by the trade name Loniten). That is, not all antihypertensive medications are bad for hair. Some may be the solution to the problem!

31- Non-steroidal anti-inflammatory drugs

NSAIDs (Non-Steroidal Anti-Inflammatory Drugs) are common medications for the relief of inflammation, pain, and fever, and are used against headaches, muscle aches, arthritis, and even colds and flu. Some of the most common are ibuprofen, aspirin, diclofenac (Voltaren, Cataflam), and acetaminophen (Tylenol).

The use of these drugs is very unlikely to cause any effect on the hair . The greatest risks involve higher doses or longer periods of use, and even then it may be that the hair loss only appears at the beginning of the treatment and disappears after the body gets used to the medicine. If the drop is persistent, your doctor may examine other medications or change the dose to try to mitigate this effect.

32- beta blockers

Beta-blockers or beta-adrenergic blocking agents are substances used for the treatment, among other cases, of hypertension, arrhythmia, glaucoma and the protection of the heart after episodes of heart attack.

Although they are used in some cases of hyperthyroidism (which is a disease that can interfere with hair loss), beta-blockers tend to treat only some of the symptoms (such as increased anxiety, tremors, etc.), without greatly affect the levels of thyroid hormones in the body.

Hair loss usually lasts only while you are taking the medication , but if the treatment is long-term it is worth consulting with your doctor to rule out the suspicion of other causes of the problem (in cases of hypertension, hair loss may be associated with low levels of zinc, for example), or discuss the possibility of making adjustments in treatment. Remember that other antihypertensive remedies can also be behind hair loss.

33- Corticosteroids

Corticosteroids are a class of anti-inflammatory drugs used to treat allergies, inflammations, and autoimmune diseases. They are powerful tools in the fight against some diseases that cause hair loss , such as lupus and alopecia areata .

The difference between the hero and the villain in this case is the dosage. Very high levels of steroids in the body can cause Cushing’s syndrome , which is associated with hair loss . In these cases, it is best to speak with your doctor and consider reducing the dose or trying a different medication.

34- Lithium

Lithium is used primarily in medications to treat bipolar disorder . Hair loss can arise as a reaction to the effects of medication ( telogen effluvium ), but one of the possible side effects of treatment is hypothyroidism, which can also cause the problem.

The first step is to do tests to see if thyroid activity is normal. If there are any changes, treatment to normalize thyroid function may be enough to stop hair loss. If this is not the case, you should take into account that the hairs stop falling out after a few months (which happens in some cases, after the body gets used to the lithium treatment). Consult your doctor if you can make any changes in the medication or the dose so that there is less damage to the hair.

35- Chemotherapy and radiotherapy

Cancer is a disease (or a group of diseases, really) in which a group of cells begins to reproduce in an uncontrolled way, which can affect the tissues of the region where they are found or other parts of the body.

The drugs used in the treatment of this disease cannot distinguish what is cancer and what is not, what they do is attack cells that have the characteristic of multiplying rapidly. The problem is that hair follicles also involve intensive cell multiplication in hair production, and are often affected by treatments.

Some medications can cause all hairs to fall out (not only on the head, but also on other parts of the body). Others only make most of the hair thin and brittle and can also change its color and texture.

Radiation is another cancer procedure and usually only affects cells in the treated area, so it commonly causes hair loss in cases where cancer is in the head.

As soon as the chemotherapy or radiation therapy ends, the hair follicles recover normally and hair growth resumes . Several doctors recommend the use of tonics like minoxidil to aid in this recovery. The hair prostheses are great options to cover the bald areas until the natural hair grows back normally.

36- Remedies for cholesterol

Medicines such as statins are commonly used to treat high cholesterol levels , but a possible side effect of their use is further hair loss. This can occur as a reaction of the body to the drug (classic case of telogen effluvium ), but perhaps the “fault” is exactly the reduction of cholesterol. Cholesterol is important for the production of hormones in our body, and the fluctuation of its levels can have effects on the hair (such as hair loss after childbirth, in menopause or classic androgenic alopecia ).

Cholesterol control is important to avoid blockages in the veins and arteries and reduce the risk of heart attacks or strokes, for example. Therefore, you should never stop medication on your own simply because your hair is falling out. First of all, you need to make sure that medications are the real culprits for hair loss (checking thyroid health, hormone levels in the body, nutritional deficiency, etc.), so talk to your doctor about the options available for your treatment.

37- Remedies for Diabetes

There are several medications for diabetes, but not everyone reacts well to all of them. Virtually any drug can trigger telogen effluvium , but in this case it can be a second complication. Some drugs used in the treatment of diabetes can reduce the absorption of certain vitamins, especially those of group B, which can cause hair loss . These vitamins also affect the absorption of iron, another critical component to prevent hair loss.

First of all you must make sure if the cause of the fall is not the diabetes itself. If even with the stabilization of the disease, your hair continues to fall, you may consider with your doctor the possibility of adjusting the medication or investigate if the case involves some nutritional deficiencies.

38- Remedies for Gout

Gout is a disease related to increased levels of uric acid in the blood. The deposit of crystals formed by acid in the joints can cause pain and inflammation.

Some of the medications used to treat gout, such as allopurinol and colchicine, can have the side effect of hair loss or discoloration, but these events are rare. It is common, that to control inflammation, certain corticosteroids and NSAIDs are also used, which can make the hair fall more than normal. The use of anticoagulants can worsen both frames (fall and more fall!).

Some other diseases can often affect people with gout, such as anemia, psoriasis, hypothyroidism, high blood pressure and diabetes, all of which can cause hair loss, so each case must be investigated carefully. careful. Talk to your doctor about doing tests to rule out disease and testing medication changes to identify the real culprits.

39- Remedies for the thyroid

Both hypothyroidism and hyperthyroidism can cause severe hair loss, and treatment to normalize thyroid activity usually resolves these cases. However, if the dose of the drug is not well regulated, it can cause the opposite effect : hypothyroidism can turn into hyperthyroidism and vice versa (which can cause hair loss to return).

To avoid this effect, it is necessary that people receiving thyroid treatment are regularly monitored by a doctor, making periodic tests to assess whether there is a need to increase or decrease the dose of the drugs.

40- Retinoids

In theory, retinoids can both increase and decrease hair loss . They are substances that interfere with the regulation of skin cell growth, and are widely used in the treatment of acne and psoriasis. Tretinoin, isotretinoin (the active ingredient in Roacutan or Roaccutane), and adapalene are some of the better known retinoids.

It is believed that the action of these drugs on the skin can interfere with the activity of the hair follicles, but there is another clue that may be important: retinoids are formed from the structure of vitamin A (whose excess is also associated with hair loss ).

Interestingly, some studies indicate that the use of topical retinoids (such as creams, lotions, or gels applied superficially to the skin) can inhibit hair loss, especially when associated with the use of minoxidil lotions. This appears to increase the sensitivity of the skin and amplify the effects of the treatment.

Which may suggest that systemic treatment (which works in the body, such as tablets) could cause more hair loss than topical treatment . However, if you use retinoid medications, it is worth consulting with your doctor to evaluate other alternatives.

Diseases and health problems

41- Accident

Faced with the physical and medical injuries and stress involved in an accident, the body faces a shock. Hair loss can appear months after the accident, but once it is recovered, the hair follicles will return to their normal activity.

If there is physical trauma to the head, we have to wait for the healing to complete to see if the hair will be affected. In some cases, hair stops growing if the scar is very large. It is possible to do a surgical intervention on the scar, reducing its length, or even a hair transplant .

42- Alopecia areata

The alopecia areata is an autoimmune disease in which the body starts attacking hair follicles as if they were invaders. In most cases, “islands” of baldness appear on the scalp (well-defined bald areas), although some people suffer from diffuse alopecia areata. Hair loss can progress or reverse spontaneously, and it is normal for several episodes to occur throughout life.

There is no definitive cure as of yet, but we already have several treatment options for alopecia areata ( click here to learn more about them ). In more advanced cases, hair prostheses can be a good aesthetic solution.

43- Scarring alopecia

What is called scarring alopecia is not a single disease, but a set of events that can cause permanent damage to the hair follicles and create permanent bald spots . This includes everything from physical damage (such as burns, accidents, or a scarred area from surgery) to a number of inflammatory diseases that can directly or indirectly affect the follicles ( read more about them here ).

Many of these diseases have a chronic occurrence (the episodes are repeated throughout the individual’s life) and can be confused with other types of alopecia or some mycosis. The investigation of all cases must be taken seriously, precisely so as not to run the risk. As scarring alopecia can cause irreversible baldness, the correct treatment should be started as soon as possible.

44- Surgery

Surgery always creates an impact on the body, and we have seen that telogen effluvium is common in these situations. The greater the surgery, the greater the chance that the reaction will also occur.

Some people believe that the method of anesthesia could play an important role in these cases, especially if it is general anesthesia . In theory, only the fundamental processes of the body could be kept at work, and others (such as hair production) could be left on stand-by . This temporary “closure” could cause the follicles to prematurely enter the telogen phase, causing severe hair loss.

Whether or not this is the case, the truth is that hair loss after surgery usually tends to heal in the following months, when the body recovers. A possible exception to this rule is surgery of the digestive system (such as stomach reduction or removal of part of the intestine). Some of these procedures can cause malabsorption syndrome and endanger hair growth . In such cases, you will need to speak with your doctor to evaluate dietary supplementation or adjustments that may be necessary.

The scar left by surgery can also be a cause of hair loss. In some of these cases, it is possible to do a hair transplant to restore the affected area.

45- Seborrheic dermatitis (dandruff)

The seborrheic dermatitis is a problem that causes the skin is extremely flaking (which causes dandruff), and cause redness, itching, irritation , and in some cases, hair loss. Its presence seems to be related to genetic, climatic factors (it is more common in cold climates) and emotional factors ( stressful situations can trigger a crisis) . Other events apparently related to seborrheic dermatitis are excess oil and an increase in the amount of a type of fungus that normally lives on the skin (as in the case of pityriasis versicolor).

The treatment is carried out usually with antifungals, special shampoos (such as ketoconazole ) and corticosteroids . It is believed that poor diet and smoking can worsen seborrheic dermatitis, as well as baths with very hot water and the use of accessories that “drown” the head a lot (such as hats and scarves, for example).

46- Diabetes

The occurrence of hair loss in people with diabetes (related to the disease in blood sugar levels) is common, but the reasons can be many :

• Blood flow can be affected, compromising the supply of nutrients to the hair follicles and causing them to reduce their activity.
• Other diseases such as Cushing’s syndrome, hypertension, hyperthyroidism, and polycystic ovary syndrome can be related to the onset of diabetes and hair loss.
• Some medications, such as corticosteroids, beta-blockers, and antihypertensive drugs can interfere with the onset of the disease. Also, several diabetic medications are used to regulate cholesterol. These may be related to hair loss, including some of the drugs designed to treat diabetes itself.
• Low levels of some vitamins are common in diabetics (and also in people with hair loss).
• Some women develop what is called gestational diabetes, which can be the cause of hair loss during pregnancy. The condition requires treatment, but it is usually only temporary.
• Sometimes your own emotional stress related to the disease can be a trigger for hair loss.

With so many elements that can influence the problem, it can seem very difficult to determine exactly which (or which) of them is the real culprit . The most important thing is, first keep the disease under control, then start the treatment, follow the recommendations of your doctor and see what happens.

If normalizing blood sugar levels doesn’t solve the problem, you can start investigating other “suspects.” Talk to your doctor about possible adjustments to medications, diet changes, supplements, and nutritional alternatives.

It is worth noting that treatment for diabetes may need to be intensified with the onset of menopause. Another warning: smoking in diabetics, in addition to increased hair loss, can cause serious health problems.

47- Acute diseases

It may sound like a lie, but even a cold can make us lose our hair! Any serious episode of an acute illness, such as an infection caused by viruses or bacteria, can put your body on alert and recovery later . As we have seen, one of the ways that the body has to react to these situations is by focusing all its resources on curing the disease, leaving less important functions, such as hair growth, in the background.

It is good that you pay attention since in most cases, the hair begins to fall only a few months after the episode. Perhaps the tonsillitis that you had a while ago may be the culprit that you are now losing hair.

It is a classic case of telogen effluvium , which usually tends to resolve after the body recovers. So there is not much to do but wait. It is normal for the body to take up to six months to stabilize, but if your hair loss persists for much longer, the cause may be something else.

48- High fever

Among the various types of illnesses and infections that can trigger an episode of telogen effluvium , cases of high fever are some of the most common culprits.

Fever is a natural self-defense mechanism of the body, which identifies the presence of intruders and increases the temperature to try to eliminate them. One of the techniques that the body uses for this is to decrease the blood flow to the skin, to keep it in a place away from the surface (where it loses heat more easily).

It may be that this reduction in blood supply affects the hair, or that the very effort of recovering from the infection requires a great deal of attention from the body. The problem can also be the medications used during the infection: ibuprofen, for example, is an antipyretic (fights fever) that can cause hair loss in some cases.

49- Hypertension

Hypertension (high blood pressure) can trigger hair loss for a number of reasons. In addition to the impact that the disease itself has on the body , several types of hypertension are associated with low levels of zinc in the body, and some antihypertensive drugs (eg, beta-blockers) can also be to blame.

The first step in these cases is to make sure that the hypertension has been treated. If hair loss persists even at normal blood pressure, it’s worth checking with your doctor to see if you’re zinc deficient or if you might change your medications (or lower your dosage).

50- Hyperthyroidism

When the hormone produced by the thyroid gland is at higher than normal levels, it creates a picture of hyperthyroidism. The body’s metabolism speeds up and this change is believed to occur in hair follicles as well, causing the hair growth cycle to speed up . This can cause hair to fall out faster than the body takes to replace it.

Hyperthyroidism can cause high blood pressure, insomnia, restlessness, anxiety, weight loss, and increased appetite. The most common treatment is with medications that lower thyroid hormone levels (some cases are treated with beta-blockers, which can also cause hair loss).

In some cases, the gland can be surgically removed or destroyed with the use of radioactive iodine, and the patient begins taking medications that contain the hormones produced by the thyroid.

In all cases the dose of the drugs should be regularly monitored by the doctor to avoid the risk of developing hypothyroidism (which also causes hair loss) .

51- Hypothyroidism

Hypothyroidism is a disease in which the hormone produced by the thyroid gland is at lower than normal levels. The disease affects the body’s metabolism, and it is believed that it can reduce the activity of the hair follicles , causing the hair to not grow with it and to come out thinner, drier and more fragile.

Other symptoms of hypothyroidism include fatigue, drowsiness, lack of energy, weight gain, constipation, muscle weakness, and dry skin . If you suspect that you may be experiencing this disease, consult your doctor to confirm the diagnosis and begin treatment. Also check that the zinc levels in your body are normal, as it is common for them to be decreased by hypothyroidism.

Once thyroid activity returns to normal, hair grows back normally . However, it is important to maintain medical surveillance to evaluate the need to adjust the doses of the drug over time (a very high dose can lead to the opposite disease, hyperthyroidism, which can also cause hair loss).

52- Lupus

Lupus is a disease that causes the body’s defense system to attack the organs. Its manifestation can be systemic (involving various parts of the body) or restricted to the skin. Several cases of lupus are associated with hair loss, but it is necessary to investigate carefully, as there are many variables that can intervene.

One possibility is that the inflammation caused by episodes of lupus activity cause hair loss, in these cases, once the crisis is controlled, the hair returns to normal. However, it must be remembered that some NSAIDs, corticosteroids, anticoagulants and other medications used can be to blame for hair loss. Some medications can even cause lupus-like symptoms, which disappear when treatment is finished.

It’s also possible that other events related to the onset of lupus, such as fever, anemia, and poor appetite (leading to poor nutrition) and even the stress of dealing with the disease, may be causing hair loss . Therefore, the investigation of the case must be done with prudence and patience, eliminating suspicions to arrive at the true cause.

In the case of discoid lupus (a form of the disease that generates circular marks on the skin), if the lesions of the scalp are aggressive and are not treated properly, they can cause a type of baldness classified as scarring alopecia with permanent damage to the hair follicles in the affected area. In some cases it is possible to regain bald spots with a hair transplant , but ideally you should wait for the inflammation to be dormant and stable for a long time (one to two years) before considering this alternative.

53- He had

Ringworm of the head (or tinea capitis) is a fungal infection that occurs most often in children, but it can also affect adults. It usually begins with reddened areas of the skin, which progress to form rounded bald regions. They can be accompanied by itching, inflammation, and scabbing. The contagion is carried out by contact with infected people, animals or objects (such as hairbrushes, hats or pillows, for example).

Pityriasis versicolor is caused by fungi that normally inhabit our skin, but they can multiply too much and begin to cause problems. It forms yellowish spots (they can appear whitish in contrast to the color of the skin) that can imply hair loss in the affected areas and itching. Some genetic, environmental factors (heat and humidity), and some health problems (nutritional deficiencies, immune problems, seborrheic dermatitis, and Cushing’s syndrome) are believed to increase the chances of the problem occurring.

In both cases, treatment is usually done with systemic antifungal drugs (given in tablet form) and topical drugs (such as ketoconazole shampoos , which are common in the treatment of hair loss). In the case of ringworm of the head, it is important that you start treatment as soon as possible , as it can cause permanent damage to the hair follicles, causing scarring alopecia .

54- Psoriasis

Psoriasis is a chronic disease (with a genetic and autoimmune history) that usually causes reddish, scaly lesions on the skin and can affect various parts of the body (including the scalp). Several episodes usually occur in the course of a person’s life.

The hair loss associated with this disease is usually attributed to the physical trauma generated by itching, the impact of inflammation, the medications used to control it (as well as some retinoids) or even the stress of having to deal with the problem. However, in severe cases the disease can cause permanent damage to the hair follicles and trigger scarring alopecia .

Psoriasis is often confused with some mycoses, which can delay early diagnosis and treatment. It is known that patients with autoimmune diseases may be more likely to express similar conditions , such as some types of hypothyroidism, hyperthyroidism, diabetes, and lupus (diseases that can also cause hair loss). One of them is alopecia areata , which also causes recurring episodes of baldness in limited areas. In addition, those who suffer from psoriasis also have a higher risk of developing hypertension.

Therefore, it is important to carefully investigate the symptoms and identify the real cause of the problem . Consult your doctor, observe the pattern in which hair loss occurs, and investigate if there are other health problems that may be causing or worsening symptoms.

55- Pituitary problems

Many of the causes of hair loss are related to different hormones. So if there is a problem with the pituitary gland, the master gland that regulates the functioning of other glands in the body, hormonal imbalances are expected to lead to several drawbacks, including exaggerated hair loss.

The thyroid and adrenal glands, for example, depend on commands from the pituitary to produce their hormones. Problems in these glands can lead to hypothyroidism, hyperthyroidism, and Cushing’s syndrome. All of these conditions can have hair loss as a symptom.

The gland also participates in the production of male and female hormones, which when unbalanced can cause changes in menstruation or interfere with the development of androgenic alopecia.

Diagnosis of pituitary gland problems is quite rare, and is usually made through blood tests and by looking at symptoms. Your doctor must investigate the case and determine the best type of treatment.

56- Problems in the adrenal glands

The adrenal glands are responsible for the production of several key hormones, such as cortisol, adrenaline, and testosterone, and they regulate the transformation of fats, proteins, and salt levels in the body.

Since these functions affect many aspects of our body, it can be difficult to obtain an accurate diagnosis. For example, some of the symptoms of underactive adrenal glands, such as tiredness, fatigue, and drowsiness, may be associated with hypothyroidism or anemia. The excessive production of hormones can cause some irregularities and the development of facial hair, symptoms that can also raise menstrual suspicions such as polycystic ovary syndrome. All of these cases can cause hair loss.

If there is an excess of cortisol in the body, either through an adrenal problem or too much corticosteroid medication, Cushing’s syndrome can develop, which can also make hair loss more intense. The already exacerbated production of androgenic hormones can accentuate the settings of androgenic alopecia.

Only a careful evaluation by your doctor, by comparing the symptoms and the indication of tests to check the functioning of the adrenal glands, is able to unravel what may actually be behind the hair loss in these cases.

57- Burns

Burns can cause hair loss in two different ways. A severe burn, especially when it reaches large areas of the body, can trigger the appearance of telogen effluvium . But if it affects the scalp, the hair follicles can suffer permanent damage, generating a picture of scarring alopecia .

The choice of treatment in this case must take into account the extent and depth of the damage caused by the burn. In some cases it is possible to recover the bald spots through a hair transplant , taking advantage of the follicles in the areas that were not compromised.

If the skin has been severely damaged and the transplanted follicles do not have a good chance of survival, or if the patient is unwilling or unable to undergo a surgical procedure for any other reason, a hair replacement may be a good solution to the problem.

58- Syphilis

This is one case where hair loss research can literally save your life.

Syphilis is a sexually transmitted disease caused by bacteria that develop in different stages in the body. In the first, starting a few days after the body is infected, there are small lesions in the genital area and buboes (swollen areas) in the groin, which usually do not cause pain, itching or other symptoms, and may disappear by themselves and without leaving scars.

In the second stage, reddish spots form on the skin, which may be accompanied by fever and hair loss. The symptoms also disappear spontaneously, but the disease may not be cured. When it reaches the third stage, syphilis can affect the nervous and cardiovascular systems , causing very serious complications if left untreated. It can even lead to death.

Because milder symptoms can go away on their own, many people overlook them, increasing the chances that the disease will get worse and cause more serious problems. So if you notice any similar symptoms, you should seek a doctor as soon as possible to confirm the diagnosis.

The good news is that syphilis can be treated and cured with antibiotics . The bad news is that you can become infected again in the future if you have unprotected sex.

59- Cushing’s syndrome

Associated with the excess of the hormone cortisol in the body, Cushing’s syndrome can be caused both by the excessive consumption of corticosteroid medications and by problems in the production of cortisol in the adrenal glands.

In addition to hair loss, other symptoms are the accumulation of fat in the body, the formation of stretch marks on the skin, healing difficulties, menstrual irregularities, fatigue and an increase in blood pressure. Some women may develop more facial hair (hirsutism).

If you suspect Cushing syndrome, it is essential that you see your doctor to measure cortisol levels, confirm the diagnosis, and determine treatment.

60- Malabsorption syndrome

What we call malabsorption syndrome is actually a set of problems that can cause the body to not absorb nutrients properly, which can cause nutritional deficiencies (which as we have already seen, can be the starting point for hair loss ).

Some of the possible causes of malabsorption are:

• Celiac disease (gluten intolerance)
• Crohn’s disease
• Ulcerative Rectocolitis
• Bile duct obstruction
• Pancreatitis
• Cystic fibrosis
• Lactose intolerance
• Parasites
• Bariatric surgery
• Surgery to remove part of the small intestine

Weight loss while maintaining a normal diet, diarrhea, and frequent nutritional deficiencies may suggest malabsorption. Your doctor should perform the necessary tests to confirm the diagnosis and determine the best treatment options.

61- Smoking

Smokers are already tired of hearing about how this is bad for their health and all the serious illnesses that can arise as a result, including some that can lead to death. But let’s add one more argument to your list of reasons to quit smoking: it can cause hair loss.

Smoking is already known to cause premature aging of the skin (including hair follicles), in addition to damaging the circulatory system (including the small vessels that hold hair down). It can also cause damage to the DNA of cells (affecting the reproduction of the cells that make up the hair) and weaken the immune system (leaving the body more vulnerable to various diseases that can make your hair fall out faster).

In addition, studies have shown that smoking can accelerate the onset of androgenic alopecia in people who already have the predisposition. That is, if you are a smoker and have a genetic predisposition, you will go bald sooner.

Psychological disorders

62- Emotional stress

Severe psychological stress situations can be as debilitating to the body as physical trauma. A change of city, overwork, worry about a serious problem, ending a relationship, the loss of a loved one or other events can cause the body to react in the same way as to an illness, focusing on the recovery of available resources and leaving out secondary functions (such as hair growth).

This problem is classified as telogen effluvium , and it can appear months after the event that caused it. Once the body recovers from stress, the situation tends to resolve itself. Do not hesitate to seek psychological help if necessary, especially if you notice that the hair continues to fall after six months.

63- Eating disorders

Anorexia and bulimia are psychological disorders that create incorrect behaviors in relation to eating. Out of an exaggerated fear of gaining weight, anorexics avoid much of their food and ingest a quantity of nutrients far below what is considered normal (often only in the form of small servings of fluids and bland vegetables, completing the fast for several days in most severe cases). Bulimics alternate periods of binge eating (binge eating) and elimination (guilt-induced vomiting after binge eating).

In both cases the appearance of hair loss and excessive weight loss (especially in anorexics), weakness and lack of energy is very common . The lack of nutrients can reach extreme levels, which pose a risk of death.

The treatment of these cases is psychological and psychiatric, and should involve long-term follow-up because they can generate other commonly associated problems such as depression, panic disorder, and compulsive behaviors such as trichotillomania (hair-pulling mania), which should also be treated. .

64- Trichotillomania

The name sounds complicated, but basically it is a compulsive behavior that leads the person to pull out their own hair. The problem is often associated with anxiety and stress management and can occur at any time in life . Some people also develop a habit of eating broken hair (a condition called trichophagia), which can cause serious health problems.

Treatment options include both the psychological to manage the compulsion, as well as the recovery of the bald areas generated by the removal of hair. Click here to learn more about trichotillomania treatments.

Natural causes

65- Aging

Age-related hair loss should not be confused with androgenic alopecia, which causes traditional baldness (and which also progresses with age). The effects that the aging tends to be more diffuse hair are : hairs begin to turn white, tend to be thinner and dry (likely to break more easily) and growth phases are each shorter time.

Not everyone sees these changes as a problem. With proper care to replenish the oils that the follicles no longer produce in the same amount (through the use of hair oils), keeping the hair color beautiful and uniform (leaving them white or dyeing them in other shades) and adopting products and hairstyles that create more volume, you can easily avoid the changes.

Of course, other factors such as nutritional aspects, medications and health problems can accentuate hair loss. So ideally, you should keep your attention on time, get regular check-ups, and talk to your doctor if there is any suspicion that some other factor may be causing your hair to fall out more than normal.
