What percentage of hair is on the human body. Interesting facts about hair and haircuts
Hair, according to some experts, is one of the most mysterious human organs. This is probably why so many myths and beliefs are associated with them. Scientists have refuted some of them, others have been confirmed, and others still remain unstudied. During the research process, many surprising discoveries were made.
Hair facts
Scientists have carefully calculated how many hairs there are on the heads of people with different colors hair. It turned out that blondes have the most of them - 120-140 thousand. Brunettes are less fortunate - they have 100-110 thousand. But red-haired people have only 80-90 thousand. However, visually, hairstyles different people are no different, and all because redheads have the thickest hair, and blondes have the thinnest.
The number of follicles on the head depends on heredity. On average, up to 20 hairs appear from one hair, each of which grows from 2 to 5 years, after which it falls out. It is considered normal if a person loses about 100 hairs per day. Compared to the hundreds of thousands that are on the head, this loss seems insignificant.
The first fuzz on a baby's head appears in the womb. It falls out during the first year of life and new, still delicate and thin hairs grow in its place. With age they become tougher. It has been proven that teenagers between 14 and 17 years old have the strongest and thickest hair. Then every year they become thinner. Gradually, the lush hair in youth turns into hairstyles that are quite modest in volume.
It is estimated that on average hair grows 1 cm per month. Interestingly, they grow better in spring and summer, as well as during daylight hours. Scientists cannot yet explain the obvious analogy with plants.
Many people want to have long hair, but not everyone succeeds. No help folk remedies and the most latest developments cosmetologists and chemists. This phenomenon was found scientific explanation. As it turns out, it all depends on the strength of the roots. Typically, hair grows to about 90-100 cm and then falls out under its own weight.
Human hair just seems fragile and thin. In fact, it can support 100 grams of weight (for example, a chocolate bar). However, it can stretch about 1/3 of its length before breaking. If the roots could hold out, an adult could lift two African elephants with his hair.
There are exceptions to every rule
All studies above reflect statistical averages. However, there are cases that go far beyond those indicated by scientists.
For example, Russian woman Tatyana Pismennaya has hair 2.7 meters long and has been growing it for about 40 years. She is not going to stop there and dreams of breaking the record of the Chinese woman Xie Quipingt, who has the most long strand has already reached 5.6 m. To be fair, it is worth noting that 
that the Russian woman’s hair looks simply luxurious along its entire length, but the Chinese woman’s beautiful hair at the roots gradually turns into a thin strand.
The longest hair among men (6.8 m) was from Vietnamese Tran Van Hei. True, he didn’t cut them not out of a desire to break a record or surprise others. He did not care at all about caring for them, twisting them into a rope and wrapping them around his head like a turban. In his case, he had to give up cutting his hair, since even a simple trimming of the ends ended in illness. An explanation for this phenomenon was never found, but they remembered the legend of Samson, who, having lost his hair, lost his strength, that is, his health.
The achievements of Bruce Khlebnikov are no less amazing. He doesn't just have long enough hair for a man. They have amazingly strong roots and are 4 times thicker than ordinary person. He moves multi-ton buses, tram cars, airplanes and pleasure boats by tying them to his hair in a ponytail.
Unusual use
Since hair has always attracted people, it was sometimes used in the most unexpected ways. This is how magicians of all times created damage and the evil eye with the help of a stolen strand. But some peoples kept the first cut lock of hair as a receptacle of primordial power. In ancient times, they found a very practical use for strands - they were used to weave strong strings for bows.
Hair is not left alone even today. Their ability to absorb oily substances was used in 2007 in San Francisco to collect spilled oil. To do this, activists collected cut hair from hair salons in the city, filled nets with it and pulled it across the surface of the water.
Italian designer Maria Lucia Mungo found a more aesthetic use for her curls. She covered her car with them inside and out, making the most unusual car tuning in the world.

Surprisingly, we are born without even knowing that just a couple of weeks before birth we were completely covered with hairs. Hair on a baby's body begins to grow while he is in the womb. Baby fuzz (lanugo) is a thin, weak hair that appears on the fetus around the 12th week of conception and falls out at the 40th week, before the baby is born. These hairs do protective function.
2. There are three types of body hair.
Lanugo or baby fuzz, discussed above, is the first type of body hair. These hairs are very thin, colorless and similar to the hairs that we see on the skin of a peach. Baby fuzz covers the skin and is not attached to the skin by roots and follicles. The hairs that appear on a child’s body from birth to puberty are light, thin and weak. These hairs belong to the second, intermediate type. They are not attached to the sebaceous glands and are easily and painlessly removed from the roots. The third type is the terminal stage of body hair formation. During puberty, hairs (especially in boys) become darker and stiffer, and their roots are firmly attached to the hair follicle and sebaceous glands.
3. Body hair is protected by microscopic glands
The sebaceous glands, which are connected to the hair follicle, perform a protective function: they produce sebum, which protects the skin and hair follicle from the penetration of bacteria. If the hair is removed from the root, work sebaceous glands does not stop, and they continue to perform their protective function. Moreover, removing body hair has certain benefits: the hairs accumulate sebum along their entire length, which can cause unpleasant odor bodies. By removing hairs, you solve this problem.
4. Evolution deprived us of hair, but rewarded us with subcutaneous fat in return.
On initial stages evolution, the human body, like the body of most primates, was covered with thick hair. However, according to one scientific hypothesis, thanks to the fact that humans learned to swim and often came into contact with water, nature decided to “make it easier”: in order to have a more streamlined body, we began to lose hair. However, in order to prevent the body from becoming hypothermic, nature has provided us with a layer subcutaneous fat, which is very thin in non-water-exposed primates, but can be very thick in humans. Thus, the function of protecting the body from hypothermia, which was previously performed by dense vegetation on the body, is now performed by subcutaneous fat.
5. Body hair has two main functions.
Body hair serves for thermoregulation. In cold weather, they stand on end to protect us from the cold, and in hot weather, they absorb sweat, like a moisture-absorbing napkin. However, as noted earlier, during the process of evolution we have lost most of the vegetation on our bodies. Now it is not so thick to fully perform the functions of thermoregulation. The hair on our body is not enough to fully protect us from the cold, nor to absorb sweat in hot weather.
6. The hairier a person is, the more intelligent he is.
According to research by American psychiatrists, people whose bodies are covered with dense dense vegetation have more high performance mental development compared to those who have virtually no body hair. Research has shown: than more hair on a person's body, the higher his IQ. Surely the people discussed in our article 10 hairiest people in the world had/have not only the most unusual appearance, but are also very smart.
7. Body hair contains muscle cells.
Surprisingly, the hair root consists of several types of cells, including even cells muscle tissue. It is these cells that are responsible for the phenomenon when your hair stands on end, when you are cold, or when you are afraid. By the way, goosebumps (a consequence of the hairs on the skin standing on end) can also appear on a dead body.
8. Body hair grows faster in summer
Body and scalp hair grows a little faster in spring-summer season than in autumn or winter. This is due to the fact that in warm time year, metabolism in the human body occurs faster than during the cold period. The rate of hair growth is also determined by the level of hormones in the body. The more in the body male hormones, the thicker, denser and darker the hair on your body will be. Sometimes in women's bodies there can be hormonal disorders, as a result of which a woman’s body may be covered with dense vegetation. This disorder is called hirsutism, and simple hair removal sessions may not be enough to cope with this problem. Hormone therapy may be required.
9. Body hair attracts the opposite sex
Although few people find the appearance of body hair aesthetic, body hair can accumulate a special, subtle odor that, on a subconscious level, attracts and excites members of the opposite sex. sexual desire. In this regard, scientists have found that most often victims of rape are women who do not remove hair in the bikini area, because it is in this area of the body that pheromones (substances that have this very special smell) accumulate the most. What is noteworthy is that the “chance” of being raped for a woman who does not remove hair from her bikini area increases in windy weather, especially if she is wearing Casual clothes or not wearing underwear.
