What are the functions of a human hair? Help

Modern women have come to grips with the extra hair on their body. Particular attention is paid to the legs. Have you ever wondered why a person has hair on his legs, and what functions do they perform? Not? Then rather read further, and you learn the improbable facts about which did not even suspect.

Everything in nature is not by chance

Are you wondering why hair grows on the legs? Many scientists explain this by the connection of ancestors with monkeys. And in fact, everything is much more banal. Surprisingly, in a man, it turns out, there is nothing superfluous. Every organ, every cell, every hair is designed to perform an exceptional function.

Initially, the hairline on the legs should help a person to keep warm in the cold season. And in the heat, when the skin is open, the hair protects the feet from overheating and burns. In connection with this, people in antiquity had a more dense hair covering all over the body. However, in the course of evolution, with the advent of clothing, close to modern, people began to actively lose hair through the body.

The second and important reason why a person needs hair on his legs is a reliable protection from insects. Ants, ticks and other insects are not at all easy to get to human skin, if it is securely covered with hair. In this way, the thicker your hair grows on your legs, the less risk that dangerous insects will bite your legs.

Are you wondering how much hair grows on the legs? You are now surprised: the hair on the legs grow very quickly, at 0.2-0.8 mm per day. And if you shave your legs, then their growth rate is even higher.
It is worth noting that men's hair growth on their legs is directly related to the hormone testosterone: the more actively the male hormone is produced, the tighter the hairline.

Shaving or not shaving, that is the question

As you can see, the hairline on the legs performs quite useful functions. Therefore, you may reasonably be interested in, is it worth it to get rid of hair on his legs? Especially this issue bothers girls who want to always have beautiful legs.

To date, the function of hair is perfectly capable of performing a variety of functional clothing. It is easy to warm up with the help of tight tights or underpants. And you can also protect yourself from insects during a picnic with pants on tight cuffs. Therefore, if you like smooth legs, you can safely get rid of unwanted hair in any way convenient for you.

Useful information

Mother Nature showed her wisdom here too. The question of why a person has hair on his legs confuses many people, especially girls, since it is this problem that causes them a lot of inconvenience. You should never forget that everything is laid for a reason by nature. Our task is only to understand why and for what this is given to us. Getting knowledge is the main prerogative of a person. Take any phenomenon in nature, any fact, and you can understand what is happening and give a lot of explanation. In this matter, which at first glance may make you smile, there is also a "truth of life." “In nature, it’s not just that,” the words of a youth song come to mind. To accept this fact is worth every person.

What are the types of hair

Indeed, two types of hair can be distinguished on a person's legs. The first ones are downy hairs, short, soft, colorless. The latter are terminal, longer and thicker. Both those and others have nerve endings. The difference between the first and second type is that the terminal grows and lives for two years, whereas the soft hair is only two months. No less interesting is the fact that the growth rate of hair, which (we know about it again thanks to scientific research) is 0.2-0.8 millimeters per day. Yes, of course, girls will not be surprised with this information. For them, hair on the legs is extremely undesirable, so the appearance of wax, epilation, and shugaring is logical. If the last word causes confusion among the male audience, then you should know that this is a process of sugar hair removal. In other words: “Sweet and smooth!”

Scientific explanation

Scientists have found the answer to the phenomenal question: "Why does a man have hair on his legs?" So, firstly, the hair not only on the legs, but also on the arms, and other parts of the body - these are sensory receptors. By itself, the skin is not so sensitive, but due to the presence of the hairline, a person can feel in the area removed from the field of view, finding a parasite or a blood-sucking insect. The last representatives, especially some of their species, are considered mortally dangerous to human life.

Secondly, the hairs on the legs warm, do not let the heat go away, and on sunny days they retain moisture. Notice how the degree of hair vegetation of southern nations differs from that of northerners.

Thirdly, the degree of hairline on the legs depends directly on the amount of the male hormone testosterone. So men with copious hair on instinct cause greater preference for the weaker sex. But, as they say, the taste and color of comrades is not. But in women there should be a small amount of testosterone, so the amount of vegetation on women's legs is strikingly different compared to men, again we are talking about physiological norms.

So the scientists answered the question: "What is the function of hair on the legs?"


Americans conducted experiments in which men and women took part. The essence of these experiments was as follows: the subjects were shaved with one leg and one hand, then placed on the skin of the smooth and hair-covered limbs of insects (parasites, leeches, etc.). The results of this experiment were predictable: it was the hairs covering the skin of people that helped to quickly respond to the presence of an insect. Moreover, the presence of hair on the arms and legs during this experiment made insect bites difficult. It took the insect more time to prepare for the bite itself, and for a person this period of time was enough to protect himself. This once again confirms the wisdom and favor of mother nature for the benefit of man.

Shave or not shave

The aesthetic side of this issue is very interesting in view of today. For men, if we rely on the centuries-old experience of our ancestors, the increased hairiness of the legs is a sign of masculinity, aggressiveness, in other words, wears signs of some kind of “alpha male”. However, given the fact that man is not a wild animal, a modern man does not want to look like a savage, for whom the word “civilization” is an empty sound. Especially worth noting is the fact that the hairline at the age of fourteen or eighteen years especially increases. Mostly this concerns young men. Begins the process of puberty, maturation, which indicates an increase in the hormone testosterone. This process is natural and quite normal, so do not be afraid of such rapid changes on your body.

As for the beautiful half of humanity, here the answer of modern society is unequivocal: women should not have hair on their legs. Girls are in a constant struggle with excess body hair, especially for hair on their legs. Again, evolution is to blame: it just so happens that men prefer lovely, kind, caring and well-groomed women, and the presence of dense vegetation causes them to be at a subconscious level of bewilderment. Why should a man protect and feed a male female? She herself can stand up for herself. Female legs without vegetation - a sign of femininity. That is why lovely ladies do not spare forces, means, suffer pain during depilatory manipulations. "Beauty requires sacrifice," the statement is very fair. Again, it should be recalled that people have long moved from caves with insects and parasites into comfortable houses, evolution continues, that is, it gives a new round.


Summarizing the above, I would like to emphasize why a person has hair on his legs. This is our evolutionary heritage, the hairs give our skin extra sensitivity, which helps to protect itself against insects and parasites in time and protect against overheating and overcooling, and also indicates a sign of the masculinity of the stronger sex.

Why does a person need hair on his legs, how and how much they grow

Few people know that hair performs several very important functions for a person. In ancient times, the human body was covered with dense vegetation, because it protected from cold, frost, insects. In the process of evolution, hair became imperceptible, but often on the legs the hair still grows thick, causing girls a lot of problems.

The hair on the head performs an aesthetic function. In addition, they protect the head from possible overheating, thermal shock, hypothermia, minor injuries.

Not everyone knows that hair on the body and on the legs helps a person to neutralize itself from insects and parasites.

Scientists have conducted several experiments, in which it was proved that the nerve endings of the bullet and terminal hair allow a person to feel the movement of an insect on the skin in time. The immediate reaction of a person allows him to find a harmful insect, preventing this bite.

Hair cover performs the function of thermoregulation:

  1. in cold frosty weather it protects from heat loss (as another additional layer of clothing),
  2. in the heat saves from overheating, as well as from sunburn.

The hair also helps the sweat glands by taking part in regulating the sweating process.

There is also a theory that a huge charge of energy accumulates in human hair, which simply disappears when they are removed or cut off.

How to get rid of vegetation

Androgen (the male hormone) is responsible for hair growth. For men, the presence of abundant hair is considered the norm. Many even believe that a man’s hairy legs are direct evidence of his masculinity and strength.

The question arises: do you need hair on the legs of a woman? It is clear that hairline has its own functions and is not a useless phenomenon. But the modern world absolutely does not accept the presence of abundant vegetation on women's legs. At the same time, dense vegetation on a woman’s body may indicate a malfunction of the endocrine system. In this case, the best options would be a visit to the doctor, testing and taking the necessary drugs. But often abundant hair on the arms and legs are a sign of the eastern nationality of the woman.

Human hair on the legs are needed, they are not useless. But at the same time they do not carry vital functions, so they can be safely removed.

Legs without hair or how to clean with shaving

The modern beauty industry offers various devices, creams, foams and gels for a comfortable shave. The disadvantage of this method is that the hair begins to quickly grow back. Therefore, this procedure is carried out regularly.

Shave legs

Depilatory cream for removing and slowing the growth of long black hair

Before use, you need to test the tool on a small area of ​​the skin in the absence of allergic reactions.

Depilatory cream

The cream is applied to the legs, richly covered with hair, and leave for 10 minutes. The chemical components that make up the cream, destroy the structure of the hairs, so that it disappears. The remains of cream with lost hair are scraped off with a special spatula.

Use wax strips

This way is painful, but effective. Heated strips are glued to the skin and sharply torn off against the growth of hairs. After the procedure, the skin remains smooth and tender for a long time. After some time, the hairs grow back, but already weak and thin.

In beauty salons offer expensive procedures for laser, electric, photo and elos-epilation. Regular use of such procedures for several months guarantees the complete disappearance of hair forever.
