There are thousands of types of hair, you know! But there must be a more specific way to classify it according to its texture, right? To say that a hair is curly, for example, is too simple and vague, as there are different types of curls!
For this classification it already exists, although it is not well known. In the United States, they have separated each type into categories according to the texture of the hair, what is taken into account is the size of the lock formed: the smaller it is, the more within the classification. Of course, all this taking into account the natural shape of the hairs. It works like this:
What are the sebaceous glands?
They are the glands that are responsible for the production of sebum , and that in the head have the fundamental function of hydrating and lubricating the hair; this production depends on the hormonal activity of androgens that stimulate secretion.
The sebaceous glands play a very important role in the type of hair you have, due to the production of natural sebum that will vary according to the diet you have, blood circulation, stress and medicines in addition to age . And hair products can treat sebum production according to your need. For example, some of the advantages and disadvantages of using a sulfate-free shampoo is that it removes sebum from the scalp and it tends to generate it again, leaving hair oilier the first few uses until it is regulated.

What are the types of hair according to sebum?
Hair is that set of filaments that start from the dermis from the hair follicles, and cover the entire head in order to regulate body temperature and increase the photoreceptor capacity of the skin, which is what produces vitamin D.
In addition to these functions, hair is of great importance especially in women, because it is the key to beauty; Having hydrated and healthy hair is synonymous with well-being, and whether you have a balanced, abundant or low sebum production will determine what type of hair you have, normal, oily or dry.
If you have a perfectly balanced sebum production, neither too much nor too little, then you will have normal hair, the fat produced is distributed throughout the scalp and when touched it will not be oily or dry.
To know if you produce sebum in a balanced way, you must take into account the following:
- If it keeps you combed
- If it looks good.

Whether it is smooth or wavy, if it is normal it will have all these characteristics which will indicate that the sebaceous glands are producing sebum in a balanced way.

You can also use lemon , prepare a lemon juice before you go to shower, after you wash your hair, use the lemon water preparation, spread it all over the scalp, leaving it to act for about five minutes and then remove it with water.

How does the environment affect the sebaceous glands?
The sebaceous glands could be affected by environmental factors such as the sun, wind, sea water, among others.
The sun alters keratin and degrades melanin , makes hair brittle and dull; While the seawater by the small salt crystals increases the friction of the hair because the crystals are deposited in the hair fiber and open the cuticles, which exposes the hair much more to be affected by external agents.
The wind entangles it and fills it with dust and all the environmental pollution such as car smoke would cause damage to your hair that can be repaired, however it is better than after a day away from home when you return, wash and hydrate it.
Do chemicals alter sebum?
The dyes, the perms, the straightening have a beautiful effect on your hair , in the end for something you subject it to all this; However, doing it over and over again could damage it, the sebaceous glands could be affected and stop producing sebum , which would make it dry and that is why it is said that it looks dull and lifeless.
All the chemicals that these products bring end up being aggressive with the health of your hair, for example, the dyes contain chemicals that penetrate the pores, damage the cuticle and greatly damage the sebaceous glands so you should use moisturizing creams to reverse the hurt.
Chemicals in general, be it the dye, the perm, the straightening, all will cause damage and especially if you do it in excess you could obtain instead of a beautiful hair to show off, a hair with a lack of elasticity, fragility and dryness.
Does diet intervene in the production of sebum?
Food is very important for the health of your hair , and poor nutrition affects the sebaceous glands, and your hair will show this when it becomes dry and weak. To have strong and healthy hair you must eat well.
You need proteins that are crucial for hair growth like cystine and arginine found in dairy, meat and eggs; but if you have dry hair then eat foods rich in fat or just eat nuts.

Type 1: Smooth
Type 1 hair is completely straight , without any waviness , from root to tip, in general, both the silkiness and natural oiliness of the hair can reach the ends without obstacles.
Even so, you can’t do without thermal protection when modeling, remember that! Frequent use of a curling iron and flat iron can turn this type of hair, which is generally healthy, dry and damaged.
- Smooth 1A (Fine) – with little body, very luminous and with a tendency to be oily and stick to the head. It is the famous straight hair, which has nothing, not even a basic element! Always use light products for their care, you will not regret it! If necessary, use specific lines for oily hair, especially when washing it: it is essential that the root area is very clean. Products that add volume are also a good option. Do not use silicones, because they can make the hairs become heavier.
- Straight 1B (Medium) – has more hair, full body and enough volume. It can contain curls made with a curling iron, at the time of conditioning, the ideal is that you use light products and switch to a moisturizer from time to time to keep the shine and the hair in order . Always apply conditioner to the tip only, just like any other hydrating product!
- Smooth 1C (Thick) – straight, heavy and very difficult to model. The hairs are so thick that you can almost see one by one when looking at the heads of people who have this type of hair. Many people from the East fall into this category (but this is not a rule, there are several with fine hair as well). To maintain the beautiful appearance, it is recommended that you wash it frequently with special products and remove excess fat from the root. The air from the dryer should not be too dense or heavy and use it only on the tips. Finally, don’t forget products to repair split ends .
Here you have information for the care of straight hair .
Type 2: Wavy
Type 2 hair is one that is not straight, but not curly enough to form spirals, the locks have a standard S shape , the actual waves. They are generally softer rooted and more susceptible to frizz / frizz .
Versatility is one of the advantages of this type of hair, which is generally easy to style, with pliers you can form more defined curls and with brushing, smooth ones with little effort.
- 2A (Fine) – almost flat, it has smoother S- shaped hair and is easy to style (both with the brush and with the BaByliss – although because it is thin it tends to return to a format close to office quickly). It does not have a lot of volume, so the ideal is that you use light products and in small quantities to style it like mousses, gels and lotions, instead of creams and ointments, otherwise it can get heavy and dull.
- 2B (Medium) – tends to be a bit frizzy and is not as easy to model, as it has a strong memory from the root. The locks have a perfect S. Ideally, you should use gel-based products or mousses to maintain the beautiful waves and anti- frizz finishers .
- 2C (Thick) – waves are intensely spaced and are starting to form loose curls. The hair is not as close to the roots as in the previous categories, they move a bit away from the head. It is difficult to model and this kind of voluminous hair, it is advisable to use mousses and anti frizz finishers / frizz . The use of activating creams for soft curls is contemplated, because that way they take shape easily (it is even possible to model a 2C to look like a curly 3A: you just massage it well and let it air dry).
Here you have information for wavy hair care .
Type 3: Curly
Type 3 hair is curly hair, although the texture of types 2B and 2C is sometimes found in this classification.
Styling hair 3 is actually shaping well-defined and symmetrical curls, which look like “spirals.” When well maintained, it is soft and full of life! Therefore, you should always be careful about hydration.
- 3A (Loose Curls) – has that kind of natural bunching that seems to have been done with a curling iron on long, wide, regular hair . It usually has enough shine and handles well with a brush. To maintain defined curls and natural beauty, the best products are cream gels, leave-ins and curl activators, as long as they are not too heavy. Choose sulfate-free shampoos .
- 3B (Tight Curls) – is more tangled than type 3A, with tight, defined and regular curls and spirals. Straightening this type usually takes a lot of work! To keep your curls beautiful, you should use good curl activating moisturizers and a powerful frizz / frizz control product . As hair tends to be drier, wash it with a hydrating shampoo , with dry hair, rehydrate the curls with a leave-in conditioner when you feel the need.
- 3C (Super Hard Curls) – the bunches are super narrow, like the tip of a corkscrew. Grouped together they look like a “vine”, but with a well-defined pattern of shape. Hair is thin and fragile and hydration is mandatory to keep this style always beautiful, not only with a mask and conditioner , but also with shampoo . Lastly, go for good, slightly heavier moisturizers like creams, butters, and oils.
The curls are always beautiful, the ideal is only to do a hairstyle after bathing, with wet hair and protected by a cream to facilitate the specific hairstyle for this type of hair. Once dry, forget about the brush or comb, as this will only break the curls and disarm the hair! If you wake up with faded and undefined curls, you can use a styling spray specifically for curly hair and reshape the curls, they will be perfect, as if the hair was freshly washed!
Here you have information for curly hair care .
Type 4: Curled
Type 4 hair is generally known as African hair . The reality is that they are dry and brittle because excess oil cannot pass through the hair, due to the texture. Therefore, it takes enough moisture to reveal its full beauty and not to break down as it grows.
One fact that distinguishes frizzy hair (like 3C) from frizzy is that it remains fully frizzy when wet (curly hair tends to curl in this condition).
- 4A (soft) – has hyper narrow curls that look like swirling, crochet hook width, well defined. It is not recommended to remove excess natural oil from the hair, so you should avoid washing every day or even adhere to the co- washing method (wash only using a conditioner – suitable for your hair type -, with the power to gently cleanse and hydrate, without stripping natural oils). If you think that the idea of not using the shampoo is very radical, then choose those that are sulfate-free, with moisturizing properties. In fact, hydration is never too much, abuse the power of the products!
- 4B (dry) – the wicks have a Z (zig-zag) shape, less defined than the 4A type. When choosing your shampoo, opt for a thicker cream that allows your hair to look healthy and hydrated. Always comb back with a wide bristle comb (and avoid using a blow dryer with a very powerful blow, of course!). Seal with some type of natural oil (such as coconut, jojoba oil, argan oil, etc., but never have mineral oil) so that moisture cannot escape. For styling, use specific conditioners and masks for this type of hair. And avoid manipulating the hair as much as possible, to minimize possible breakage and help it grow.
- 4C (no shape) – has the same zigzag pattern structure as 4B, but alternating with areas with almost no definition. It is recommended that you avoid washing it very often and if possible adopt the co-washing method (explained in type 4A) or sulfate-free shampoos . After washing, be sure to seal the hairs with some type of natural oil to retain moisture. Lastly, use super hydrating products like conditioning creams and masks. Heavy creams also help give this type of hair a longer appearance. It is recommended that you use a powerful moisturizer every 3 days.
