Why curl hair: 1 main reason

Send

Why does someone have curly hair, and someone has perfectly smooth hair? This is a scientific explanation. It all depends on the shape of the hair in cross section.

Scientists conducted a comprehensive study of the structure of the hair of different people, which allowed to draw conclusions about why hair curls. If you cut the hair and look at its cross section under a microscope, then you can see what it is in the form: ideally round, slightly flattened or distinctly oblong.

Hair with a strict round cross-section, as a rule, very tough and smooth. Usually they are black, dark chestnut, occasionally reddish color. These are peculiar to Asians and residents of the Middle East. The oval (ellipsoid) section makes the hair curly. The more pronounced the "flatness" of a hair, the clearer its curvature. A classic example of the maximum manifestation of this feature - black inhabitants of the Earth. Europeans are more prone to soft cross-section and light-colored hair: from dark blond to blond. Most often, their hair is curled only in childhood.

Also, the presence of curls is determined and hair follicles. If follicles are folded, the hair will be wavy. And if the shape of the bulb is flat - straight.

Usually, if the hair is curled from one of the parents, then this is inherited by the children. The curl hair property is the dominant sign that passes to the firstborn. However, many factors can affect curliness. Everything is determined by the state of human health. To straighten the curls, for example, can lead to illness, exposure to chemicals.

Owners of silky hair can afford less careful care of them. Haircut for straight hair - an excellent solution that will allow them to be easily styled, quickly combed and washed. This is a feature of straight hair - be smooth, do not puff up, do not get out of the hair. If the hair is curled, then you need to monitor them more carefully, so that they are in good condition and look great. So nature has ordered. However, this is not a reason to get upset. After all, she made you a rare gift - to be unique, not like the majority.

Curly hair is fragile. To curls do not turn into tow, you need to follow a few rules.

To wash hair soft warm water not to break their structure. The shampoo should be moisturizing, with natural oils.
Use a large comb with rare teeth and an antistatic coating.
Use special tools for curly hair, after washing, apply a nourishing balm or conditioner.
It is necessary to try to dry hair in the natural way, without abusing the hair dryer.
Never comb wet hair, because it causes damage.
Cut the tips regularly.
Once a week to do a head massage.
It is best to lay curls with a good fixation spray, apply mousse to dry hair. You can use the gel with the effect of wet styling. Naughty hair is easier to "tame" with the help of wax applied on the tips.

Features of the structure of curly hair

Curly hair has loose fitting scales, which makes them more dry than straight. Such strands poorly absorb moisture, they are prone to fragility. Because it is so important to properly care for curls, providing them with full moisturizing.

Curly hair because of the unique structure of the bulbs. The point is that in such strands cell division occurs unevenly. They are formed in different quantities, because in the section the shape of curly hair is oval. Such curls first grow in one direction, then in another.

Differences are present in the follicles. In straight hair, it is perpendicular to the skin, whereas for curly hair, it has a slight or significant bend. When the hair begins to grow, they repeat the shape of the follicle.

Causes of differences in structure

Why hair follicles have a different shape, scientists have not yet been able to answer. Employees of a well-known cosmetics company for some time grown hair follicles. After checking, they found that the owners of straight strands have straight onions, and people with curls - curved.

The nature of these differences has not yet been established by scientists. However, they continue their research, which allows us to hope for a comprehensive answer.

Features care for curls: what to do to stop curling hair on your head

Since the curls have a special structure, the choice of shampoo should be treated very carefully. For girls with dry hair, cosmetics with moisturizing ingredients like coconut extract, jojoba oil or licorice, etc. When split ends appear, products such as papain or sage are helpful.

Girls with curls should not use shampoos for volume, because they harm the structure of the hair. Such means open scales, which provokes the weakening of the protective forces and increased fragility.

After washing, special attention should be paid to the drying of the strands. This should be done with a towel, giving the curls a spiral shape.

To prevent the hair from curling, you can use different oils or special procedures. In addition, pull a strand will help a regular hair dryer or iron.

Fashionable hairstyles with curls: hair curly after keratin straightening

Wavy hair allows you to make different haircuts. It should take into account some features. The ideal option would be the following hairstyles:

cascade,
asymmetry,
multi-cut haircut
bean.

In this case, the cascade form is important, because haircuts without graduation will not work. Such strands do not fit well. Fans of long hairstyles suit stepped haircuts.

Variants of the cascade

This is the most successful haircut for curls. Moreover, there are several options for its implementation:

For girls with a round face fit a uniform hairstyle. Strands should slightly open cheekbones. If you need to visually stretch your face, you should lift the curls at the crown.
The cascade is similar to steps, so the curls are sheared depending on the characteristics of growth. Hard curls make the steps clear and level.
To visually increase the volume, you can lighten some strands.

To put the cascade, it will take literally 15 minutes. For this it is enough to put mousse on the strands, curl them, put and fix with varnish.

Men's hairstyles

Owners of curly hair suit the following solutions:

short hairstyles with expressive curls,
hairstyles with extended strands with a careless effect,
Korean style solutions.

Curly hair looks very stylish and unusual. To look attractive and fashionable, you need to choose the right hairstyle and learn how to care for your locks.

Why do blacks have curly hair? ↑

My study of curly hair showed that the difference between curls and straight hair is in the structure of the hair follicle (pouch) and the hair itself. For this structure of the hair meets the curl gene. It turns out the root of curly hair grows in the skin not perpendicularly, as a straight line, but under an inclination, it can be said even with a bend. With a slight tilt hair does not curl much.

If you look at the hair section, the straight hair has the shape of a circle, wavy have the shape of an oval, and curly - the shape of a human kidney. There is also a difference in the speed and uniformity of cell division. In straight hair, division occurs evenly, and in wavy division occurs unevenly from different sides, therefore the shape on the incision is kidney-shaped. Having such a shape, the hair is easier to twist into a spiral. And black people have more hair and very thin, so they have very curly.

Curly hair gene ↑

There is a simple classification of curly hair:

cool curls
Botticelli curls
just wavy hair

Naturally, we are rewarded with a certain type of hair from birth and the genes of man, which he in turn received from his biological parents, are responsible for curvature. The “curly-headedness” gene is dominant and this means that if one of the parents has steep curls, then with a 50% chance, and maybe more, the child will be born with curly or wavy hair.

However, no matter how dominant the curly hair gene is, people with very curly hair are only 15% among Caucasians, but at the same time 40% of people with wavy hair. Total is obtained by people with curly hair 55%, and people with straight hair is only 45%.

Cool curls are very naughty in a short haircut, they are easy to push, electrify and hairstyle resembles a poodle hairstyle. Wavy hair is already better styled and more obedient. However, for curly hair there is still a special care. In my next article, I will publish tips from hairdressers for curly hair, so do not miss subscribe to blog updates .

Hair curls from moisture: causes and what to do? ↑

Many women with straight or light wavy hair complain that as the humidity increases indoors or outdoors, their hair begins to curl. And apparently they are very annoying, so they ask the question "What to do when the hair curls from moisture?".

This is the fault of the structure of the hair. As I told above, the structure of the wavy hair is not uniform and different parts of the cuticle can absorb moisture in different ways, so the hair begins to curl. Unfortunately, to fully cope with this problem is problematic, because you can not remove the cause - a special structure of the hair cuticle.

However, you can try to apply styling tools, as well as some other tips that will help keep a beautiful hairstyle in a humid climate.

Cut it right. Haircuts that provide layers often promote curling hair than straight haircuts. Also, long hair less push than short.
Use a hair straightener, but do not forget to protect it from heat before it, so as not to damage the hair.
Properly dry with a hairdryer, straightening and pulling hair.
Look for professional products designed to straighten curly hair.
In order not to be disappointed in advance, think over your hairstyle, focusing on the weather forecast.

Why did the hair suddenly stop curling? ↑

And there is a reverse situation when the beautiful curls disappear, and instead of them remain dull light waves. For many women, this seems like happiness, but often it speaks of hormonal changes. Many girls are constantly wondering "How to straighten curly hair?" , but when it happens by itself, it is alarming.

Also, hair may stop curling due to length. When a woman grows her hair, she may notice that her curls gradually become not so cool.

This is due to gravity with which the hair is pulled down and the curls naturally unwind. Therefore, if you want to return the curls, then first cut your hair. Perhaps this is the case. And also important special care for curly hair read about it in the article.

In addition to these reasons, maybe this. After dyeing the hair in the salon, the hair can lose its curvature, since during these procedures the hair is artificially weighted. And also look what shampoo and hair balm you use. Perhaps you use by mistake those that straighten hair.

Straight hair began to curl: reasons ↑

Quite an interesting situation, when from birth straight hair suddenly begins to form wavy curls. Can the hair start curling themselves? This happens rarely and professionals explain this by age-related changes that occur in the hair, as well as this is often observed in gray hair.

Pregnancy and hormonal changes can also promote the growth of curly hair. In addition, moving to another place with a different climatic situation may cause waviness of curls.

How to make hair curl? ↑

Unfortunately, it is only possible to force the hair to curl by means of salon procedures. No natural and folk techniques exist. In order for the hair to be curly day and night, simply make a permanent perm. The one that was so popular in the 80s-90s of the 20th century.

But hairs that grow back will have the same direct structure, because, as I said, the structure of the hair is set genetically.

If you talk about other procedures that make your hair curly, then I will talk about them the next time the time comes for the topic "How to make curly hair?"

And, on this I have everything, now you know more about the structure of hair and genetics and can show off your knowledge in public)) Finally, I want to say that women with curls are incredibly lucky, because such hair has always been valued and appreciated. Women with wavy hair look more feminine, light, tender and subtle. They always attract a lot of attention not only men but also women. So be proud that you are the owner of such a luxurious head of hair. And finally, the funny song "Curls"

Curly Hair Care Cosmetics

If you are the owner of curls, you should choose special products for the care of curls that will moisten them and nourish the roots.

Medium curly hair should be washed with shampoo, which includes aloe extract and coconut oil. Also for curls very useful jojoba oil. Try to choose a shampoo that can prevent hair statics, but at the same time will give them volume.

Balms and masks for curly locks are best used with special serums. They make the effect of shine and volume longer. Serums perfectly look after hair. It is necessary to apply them 1-2 times a week. The use of balms and masks will help soften the effect of shampoo.

Dyeing curly hair should be exclusively ammonia-free paint, because ammonia is very bad for curls and makes them dry, and curly curls in no case can not overdry.

If your hair is curled, you need to wash and dry it in a special way:

Use only soft water.
Keep wet hair in a towel for a long time.
Do not dry the curls with a towel and, if possible, let them dry naturally.

Salon straightening procedures and homemade masks

If your hair is frizzy, and it causes discomfort, or you want to change your image, you can straighten it for a sufficiently long period of time with the help of salon procedures. The most effective method is keratin straightening hair structure. Even the most curly curls can be weighted and aligned. The procedure is absolutely safe and is aimed at hair care and nutrition. The effect lasts up to two months, depending on the length.

Another salon treatment is Brazilian straightening. It uses keratin and natural oils. To consolidate the procedure, hair straightened with an iron. It is not entirely useful for curls, but it helps to achieve a stunning effect.

At home, you can prepare masks that straighten curly hair (photos of the final result are just amazing). The effect of straight strands will last a maximum until the next shampooing, so if you need only a lasting effect, you should contact the beauty salon.

Gelatinous mask weights the hair and aligns it to the maximum. Dilute five tablespoons of gelatin in water, add any balsam and mix to a slurry. Apply to hair and be like that for one hour.

Egg mask with the addition of peach oil. For cooking, you need to mix into a homogeneous mass two eggs and five to seven drops of oil. Apply to hair and rinse after 30 minutes or one hour, depending on how much curls curl.

Curly hair has its own characteristics, so for owners of curls medium and long, slightly sloppy loose hair or a neat tail are perfect. Now the most ordinary braid is very relevant. On curly hair, she looks pretty cute and attractive.

If you want to give a special shape to your hair, you should use foam or styling powder, they will make the curls more docile.

Short curly hair. What to do with them?

Owners of short curls fit neat caret. It should be noted that you need to visit the master every two or three weeks, because curly locks begin to grow, and the shape of the haircut changes dramatically. Protect your hair from the environment: apply mousses and balsams daily. Try as little as possible to align or blow-dry short curls.

If you want to remove the curls from the face, you can make a magnificent bundle and decorate it with various hairpins and rubber bands.

Curly Features

But, surprisingly, it sounds, scientists still have not managed to explain why some people are born curly, while others are not. The most common explanation for the phenomenon is genetic predisposition.

In this case, under a microscope, a section of curly hair has an oval, slightly flattened section, as well as a folded hair follicle and dry scales. That is why wavy hair absorbs moisture worse, loses it faster and is the most capricious in the care, requiring more attention from their owners.

Each hair is 90% of the special protein keratin. The principle of permanent perm is based on changing the bonds inside the protein, which is why hair modifies the structure. The strength of the impact, perm is considered the most aggressive and more spoils the hair. Therefore, curling hair is more harmful than straightening it for a while.

Why does hair change

It happens that the hair starts to curl unexpectedly, even for those who always wore a straight hair (see How to straighten hair). Why the hair suddenly began to curl or, on the contrary, lost their curly perky look.

There can be several explanations:

Climate change. Warm air along with high humidity often leads to the fact that the curls become wavy or straighten.
Diet The lack of individual trace elements, or their surplus, change the composition of keratin. To establish an accurate picture, it is better to keep a food diary and consult a doctor with him.
Hormonal changes in the body. Pregnancy, puberty, menopause, can lead to changes in the structure of the hair up to the most cardinal: curly, they can be straight, or vice versa.
Acceptance of some drugs.
It happens that the reason why the hair began to curl (or they suddenly lost their curliness) is an age-related change: over the years, the strands become thinner, turn gray, irreversibly changing the structure.

You should know it! Remember that frequent staining makes the hair shaft heavier: the coloring pigments penetrate it rather deeply and under their “weight” it gradually straightens.

The secrets of the wavy styling

How to make hair curl, to ensure that the waves lie beautifully longer? Modern care products, as well as tricks of the stylist, will help your strands to look not only attractively wavy, but also heal the follicles from the inside.

Curl beautiful curls will help the following techniques:

It is necessary to wash the head with special shampoos for hair straightening: they do not weigh down strands, and also moisturize them additionally.
You need to dry with a diffuser, which raises the roots, gives them volume, and also slightly twists the strands.
On the eve, you can turn to the stylist, so that he slightly curls the profile: this removes the extra weight, makes the volume easier, it becomes easier to curl the curls.
Sometimes this trick helps: pigtails are woven the night before, and in the morning they bloom and are moistened with gel or foam, only slightly combing it with your fingers or a comb with sparse teeth. This hairstyle gives a fashionable slightly sloppy look.

Fashion advice! You can dry your head, taking the hair in the palm of your hand, and then slightly squeezing it. The effect will increase if you apply a little gel with strong or medium fixation to the strands. And one more trick - if you press small and rare strands in your fist, then the curls turn out to be smaller. If you immediately grab large - curls come out wavy.

Want to know everything

Scientists have long wondered why some people have their hair curled and others not or in some places on the body their hair curled, and in others straight. At this point there are two reasons for answering the question: why hair curls - this is the shape of the hair and the shape of the bulb.

Let's find out more about this ...

As we know, even from the school course of biology, hair grows through the formation of new cells. The capillaries, which are located in the hair papilla, “fit” to the hair bulb from below. Above it actually occurs cell division. In straight hair, this process occurs evenly, as shown in the photo below.

In wavy hair, however, the division is uneven - the cells are formed from different sides in an unequal amount, therefore in the section wavy hair has an oval shape.

Curly curls tend to grow first in one direction, then in another. This is due to the fact that the formation of cells occurs alternately on different sides of the hair. In the hair cut, which curls is a reniform shape.

Interestingly, the shape of the hair can be a sign of race. For example, Indian hair is completely straight, because the hair is cylindrical, but the hair on the heads of black people, on the contrary, curls strongly, because in section they have the shape of an ellipse.

Having studied the laboratory conditions of hair follicles (bulbs), French scientists have noticed that in people with curly hair, the follicles have a curved shape, while in people with straight hair - even. This is due to the bulb itself, which directs hair growth. The follicle of the straight hair is perpendicular to the skin, the wavy has a slight tilt, but the curly has a significant bend.

As the hair grows, they begin to repeat the shape of their follicle. This is the answer to the question why the hair is curled.

This fact was determined by French scientists many years ago, when trying to create an effective tool that can change the structure of the hair. Until now, experts are trying to derive the formula of shampoo, which would easily make the hair straight or curly.

However, scientists are still puzzled by the influence of which element of the hair from birth in the human body take a certain form.
