Interesting facts about body hair. Forehead and hairline Xiang Ming Separately touch the beard hair

And so on) it is important to influence the hair follicle when it is in the stage of anagenesis - that is, it is actively growing and therefore there is access to the hair papilla. In other stages of the hair's life, access to the papilla is absent, and after the physical extraction of the hair shaft, new hair will grow in this place.

Hair Life Cycle, drawing by [Morris] Anagen stage- this is a period of active division of epidermal cells and melanocyte cells that produce melanin. Hair is one of the fastest growing tissues in the human body. Cell division creates pressure inside the hair follicle, pushing the substance into the area of ​​keratinization, or keratinization. Hair nourishment is provided by the blood vessels of the papilla. Hormones also flow to it through the blood: androgens lengthen the phase of active growth, which is why, with hirsutism, the vellus hair begins to lengthen and regenerate.

When cell division is reduced, the hair follicle shrinks - a transition period begins, or stage catagen... During this period, the hair papilla atrophies, so the cells deprived of nutrition stop dividing, and the hair goes into telogen stage- this is the resting phase. The hair follicle separates from the papilla and begins to move to the surface of the skin. At this time, a new hair follicle begins to form around the papilla, and the hair growth process starts anew.

Table 1. Hair life cycle, number of follicles, growth stages and depth [Morris, Richards]

Knowing how many follicles are located on a given part of the body, how many of them are at rest, and how many are actively growing, helps to estimate the time it will take to epilate this area, how often it will be necessary to repeat procedures and how many of them are likely to be required. ... The hair growth program is genetically based and differs from person to person, so the numbers in the table are just a guideline. Hormones can significantly affect the growth rate and the entire life cycle of hair.

Let's take a look at the table using the armpits as an example. Here 30% of the hair is in the anagen stage. This means that with the best outcome, the first time you can get rid of 30% of the hair in this area. The telogen stage for axillary hair lasts 12 weeks, we will add 2 more weeks for the hair to appear on the surface (the product of the growth rate and the depth of occurrence) - in total, at least 14 weeks to treat all the hair in the armpits. The intervals between treatments should not exceed 16 weeks (the time during which the hair is in the anagen stage). Alas, this is an idealized case: in reality, no type of hair removal allows you to remove 100% of anagen hair, therefore, hair removal in the armpits instead of 3.5 months.

Hence, it follows that it is pointless to remove hair from the sleep stage. However, this is not quite true. If we are talking about electrolysis, then during thermolysis, the heat center can touch the incipient new hair (more about that). For laser hair removal, this is also partly true if the hair has already begun to grow, because in this case, this hair already has something to absorb the radiation energy. But all the chemical methods of slowing hair growth on telogen hair will not work at all.

If you understand this material, then imagine the situation: you plucked the hair on the chin and legs, then grew it up to 5 mm and went for electrolysis to get rid of the hair forever. Now answer the following questions, but don't peek at the answers. Just check yourself:

1. Where will hair grow back faster and why?
2. Where will hair need to be removed more often and why?
3. Where will the result come faster and why?

Correct answers in my opinion:

1. On the face, hair will grow back faster, but the growth rate has nothing to do with it. The fact is that the anagen phase here is one of the longest, therefore, the hair in early anagenesis - when the hair grows, but has not yet appeared on the surface of the skin - is much larger than on the legs. So after a week or two, this hair will grow back and it will seem that previously treated hair has grown, but this is not the case. This explains the fact that the person is initially processed at least 2 times a month. After a while, hair growth is synchronized, and you can go to the procedures less often. On the legs, most of the hair is in the sleep stage, so after the first removal it will seem that the hair is "going away" perfectly, but in reality it is just asleep.
2. On the face again. I am sure that you answered this question for sure correctly. Although in reality facial hair has a very long anagen growth phase and pauses between treatments are acceptable for several months, no one wants to grow a bushy beard and walks more often.
3. Most likely, the legs are faster, and here's why: 1) this is a hormone-independent area and the hair below the knee is all terminal, so there will be no gradual degeneration of vellus hair; 2) the full cycle of hair growth on the legs is shorter. Formally, the telogen phase of the hair on the chin is much shorter than on the legs, so the first full cleaning on the face will be twice as fast; if all hair could be removed the first time, then three months would be enough for the face (telogen phase + conditional 2 weeks for hair regrowth from early anagen), and for legs it would take 4-5 months.

Hair growth phases include active, intermediate and final stages.

Hair can be renewed several times during its life.

The cyclicality of hair growth is often compared to the development of plants throughout the year: in the spring, roots are formed, goes in summer active growth, fueled by nutrients from the earth, in the fall comes a period of extinction and gradual withering away.

Hair has two parts: living and dead. The first is located under the epidermis and is responsible for growth and structure, the second is the outer cover on the head, oh external appearance which people care so thoroughly.

Hair that is visually attractive with good shine is often referred to as "bouncy" hair. However, the outer part, called the core, is made up mostly of dead cells.

It has three layers:

• cuticle, which performs a protective function and is important for the appearance;
• cortex, which is responsible for strength, elasticity and color;
• medulla - the central trunk, through which nutrients are supposedly supplied to the outer layers.

The appearance of the curls on the head largely depends on the condition of the cuticle, which includes many keratin scales.

In the normal state, they fit tightly to each other, if damaged, they separate, forming voids.

Such processes begin if the hair is exposed to intense physical and chemical stress.

In this case, the hair loses its shine and elasticity, becomes brittle and unattractive.

On the appearance strands are primarily influenced by the condition of the bulb (root) located under the epidermis and surrounded by the follicle.

An interesting fact is that the shape of the hair follicle determines the type of hair: curly ones grow from a kidney-shaped follicle, straight ones - from a round one, and curly ones - from an oval one.

The hair follicle and the surrounding pouch are placed in the dermis and feed from the subcutaneous fat base and the circulatory system through the papilla (papilla).

Also, under the epidermis, adjacent to the follicle, there is a sebaceous gland, which is responsible for grease and antiseptic protection.

The intensity of the functioning of the cells of the papilla and follicle determines the stages of hair growth.

Three main phases of growth

About 85% of the hair on the scalp is in a growth stage called anagen. The duration of this phase can be several years - from two to five.

On average, the hair grows by 12-15 mm within a month. The growth rate depends on the time of day and season; it is more active at night, in spring and autumn.

The hair follicle is formed in the dermis, it feeds on nutrients through the nipple. In the anagen phase, the processes of cell division are as intensive as possible.

The root thickens and stimulates the growth of the derivatives of the epidermis - the rods. As life progresses, the root moves closer to the epidermis, moving away from the nipple - the source of nutrition.

The papilla functions during the entire active phase, however, the distance of the bulb from the papilla contributes to the disruption of normal metabolic processes.

During this period, growth slows down and gradually stops altogether. This stage is called catagen or the intermediate phase before the stage of shedding, it lasts up to three weeks.

The follicle contracts and stops performing its functions. The nipple also gradually slows down activity.

The third, final stage is called telogen or resting phase. During this period, the hair does not grow, but continues to remain on the head.

The hair follicle is no longer nourished from the follicle and gradually atrophies. The rods lose their elasticity and fade away.

This stage can last up to three months, then natural loss occurs.

It was found that every day a person loses about 100 rods, which include mainly hair in the telogen phase.

Such losses are not critical, since the number of rods on the cranial vault can reach 150 thousand.

If the loss is more intense and the process progresses, then this indicates a disturbance in the body or the presence of a disease - alopecia.

The problem of falling out is quite common, therefore, among consumers, there is a high demand for cosmetics that counteract this phenomenon.

In most cases, prolapse is a natural physiological process.

The nipple resumes its activity after a certain period of time and contributes to the formation of a new hair follicle from mother cells.

The developing root pushes out the keratinized parts of the predecessor.

Removal of rods from atrophied hair follicles can also occur during combing or other physical impact on the hair.

The intensity of hair growth changes throughout life, this process is most active at the age of 16-24.

In older people, hair becomes thinner and grows more slowly - up to 11 mm within a month.

Causes of premature loss

The structure and appearance of the hair depends on the processes occurring in the subcutaneous part: inside the bulb, follicle and nipple.

With a deficiency of nutrients, the root can prematurely atrophy, and the shaft can lose its elasticity and shine.

Special cosmetics help to normalize these processes in case of imbalance or other disorders.

For example, hair can become dry if the secretion secreted by the sebaceous gland is not supplied in sufficient quantities, and, conversely, oily if increased secretion occurs.

Improper coloration can destroy the hair follicle under the influence of deeply penetrating chemical elements, which will lead to a premature transition to the catagen stage.

Loss or growth retardation is mainly caused by dysfunction of the follicle and nipple. Timely therapy contributes to their recovery.

Medicines are focused on reducing the resting phase and stimulating the activity of the follicles. Weakening and thinning are also signs of root disturbance.

Therefore, all treatment methods are aimed at strengthening the hair follicle, follicle and the resumption of the functioning of the nipple.

Hair care presupposes, first of all, respect for the roots - the sources of life for the hair.

The hair follicle consists of undifferentiated epithelial cells. In them, mitosis is constantly carried out and cells are formed, due to which hair growth and the renewal of cells of the internal epithelial vagina take place. In this case, individual areas are determined that give cells for certain hair formations.

The medulla of the hair is formed from cylindrical, slightly pigmented, with keratohyalin grains in the protoplasm of cells located opposite the apex of the papilla. On the sides of this area there are cylindrical cells with a large amount of pigment and tonofibrils in the protoplasm, from which the cortex is formed. Pigmented cells located on the periphery of the bulb give rise to the internal epithelial sheath. There are branched Langerhans pigment cells between the cells of the bulb.

Hair change in humans is a normal physiological phenomenon. It occurs gradually, which can be associated with their non-simultaneous laying in the mother's womb.

The keratinized bulb, together with the internal epithelial sheath, exfoliates from the hair papilla and resembles a panicle (hair bulb). The papilla atrophies, the hair follicle separates from it, and the dead hair rises up the follicle. The internal epithelial sheath surrounds the flask, shortens, and in place of the former, somewhat elevated, papilla and bulb, a connective tissue cord is formed.

Under the influence of the vital activity of the external root sheath, the hair follicle is squeezed upward. At the narrow neck of the funnel, the follicle gets stuck due to bulbous swelling and lingers for some time (up to 3 months), then falls out.

As a rule, hair growth resumes while its predecessor is still in the follicle. Due to the multiplication of cells, the papilla thickens and begins to descend into its place, while it is located slightly higher. The epithelial cells of the papilla and the epithelial cord, which connect the bulb of the shedding hair, also multiply. Epithelial cells form three layers: the inner epithelial sheath is formed from the outer two, and the hair is formed from the middle one. A new hair is making its way, at the same time there are two more hairs in the follicle.

In the process of physiological hair change, the neuroreceptor apparatus of the skin undergoes a kind of cyclical changes. First of all, the nerves of the hair papilla change. Before the loss of the old, non-fleshy nerve fibers grow in the papilla, at the same time dystrophy begins in the bulb, it separates from its papilla, and the non-fleshy nerve fibers cease to perceive the paint and are not detected. The papilla of the new hair is re-filled with non-fleshy nerve fibers.

In addition to the usual, physiological, there is a change in hair in the form of cone formation, which develop from protrusions of the cells of the outer epithelial sheath. The development of cone hair is almost indistinguishable from embryonic evolution. The grown vellus open into the hair follicles of old hair, and therefore 2 or more hairs grow in one follicle. The process of change begins in the intrauterine life of the fetus and occurs throughout a person's life.

Scientists distinguish the following phases in the life of a hair:

• growth stage (anagen);
• transitional (catagenic);
• resting stage (telogen).

The scalp contains about 100 thousand follicles, producing hair at a rate of 0.35 mm per day. Per day long hair heads grow at a rate of 0.1 to 0.5 mm. Thus, in 1 month they can lengthen by 3-15 mm. According to observations, in persons from 25 to 34 years old, head hair grows by an average of 0.4 mm per day. They grow fastest between the ages of 15 and 30. In the region of the crown, they grow by 0.35-0.4 mm, in other areas of the head they grow more slowly. Growth occurs cyclically, the cycle lasts for years, then a rest period begins for several months, after which the old hair falls out and a new growth cycle begins. Each follicle has its own cycle, independent of adjacent follicles.

The anagenic phase lasts from 2 to 3 years, sometimes up to 20 years. On the scalp of an adult, the duration of the anagen phase is from 2 to 6 years, the catagen phase is from 2 to 3 weeks, and the telogen phase is from 3 to 4 months. Normally, 85-90% of hairs are in the anagen stage, 9-14% are in the telogen stage, and only 1% are in the catagen stage. In the telogen phase, 25 to 100 hairs fall out of the follicles every day. In adolescence and adulthood, they are in a state of physiological change. The duration of existence of each hair is from 50 to 150 days, long female hairs grow for several years. The average size of long scalp hair reaches 60-75 cm when changing after 5-7 years. Longer (1-1.5 m) are rare - usually in girls under 15 years old. Hair grows faster in women than in men. The period of changing long hair in men is usually shorter (from 6 months to 2 years) than in women, and due to pathological processes they lose them earlier and in greater quantity than women. But in men they regenerate faster (90-100 days) than in women (144-147 days). Their growth rate depends on age.

With age, the development cycle is shortened: they become thinner, thinner, lose strength. The number of hairs in the catagen phase gradually increases. Their growth rate decreases significantly between 50-60 years. In older people, their length is shortened and long hair is very rare.

The anagenic phase of hair growth in different places of their location varies with respect to the resting phase: in the eyebrows, the anagen phase lasts 4-8 days, and in the ear canals - 7 weeks. Their growth cycle on the cheeks and chin lasts about 12 months, while the anagen phase lasts 7-10 months and the telogen phase lasts 25 months. Hair on the extremities, excluding the hands and feet, remains longer in the telogen phase than in the anagen phase, and in the axillary cavities and pubis, the telogen phase is shorter than the anagen phase.

Hair of the head is more prone to loss than in other parts of the body due to its frequent presence in the anagen phase and more dense location (up to 600 follicles per 1 cm 2). If every day about 70 hairs are normally shed, the same amount is included in the 2nd and 3rd phases. According to American dermatologists, the fastest growing hairs are eyebrows (64 days after plucking until hair appears above the skin surface) and beards (92 days). There is no definite data on the mechanism that controls the duration of individual phases of hair growth in humans. It is believed that this mechanism is genetically determined. Hair loss begins in resting follicles. This fact is explained by the hypothesis that the mitotic inhibitor, which accumulates during the active anagen phase, is used or disappears during the resting phase.

Scientists believe that the intensity of hair growth in healthy men of various ages at the crown of the head, that is, where bald spots usually appear, is weaker, apparently due to the fact that in this place the anagen phase is shorter. The growth rate slows down at night, and increases in summer.

In the growth stage, a high content of glycogen is found in the cytoplasm of the epithelial cells of the upper third of the hair follicle, while in the transitional and resting stages, the level of glycogen decreases. In the resting stage, the amount of lipids in the hair papillae increases. As follicles and papillae grow, they are enriched with amino acids. They are initially rich in nucleic acids. In the course of keratinization, the amount of ribonucleic acid (RNA) in all cells, except for embryonic ones, decreases; relatively much RNA remains in the cortex of the cortex. Acid phosphatases are histochemically found in the external and internal epithelial sheath, in the keratogenic zone of the hair follicle. Alkaline phosphatases are found in the papilla of the connective tissue membrane of the hair follicle.

Hair growth is regulated by the nervous and endocrine systems, it is influenced by vitamins, the general condition of the body and even the composition of food. The relationship between hair growth and the state of the nervous system confirms the fact that after removal of the stellate ganglion, the hair on the side of the operation grows longer.

Impact on nervous system leads to a reduction in the number of mitoses, and this is manifested in the narrowing of the hair. By the number of constrictions on the hair shaft, one can calculate the number of mental trauma or serious nervous experiences in patients.

In all likelihood, genetic factors act on the follicles through hormones. Observation of patients with endocrine disorders suggests that androgens and glucocorticoids prolong the hair growth phase. Cortisone and estrogens accelerate the onset of the anagen phase after the telogen phase. Administration of ACTH to animals slows down hair growth. Moderate and short-term hyperthyroidism promotes increased growth, and if hyperthyroidism was prolonged, hair began to grow more slowly.

Sex hormones do not affect the vellus hair of eyebrows, eyelashes, nose, and ear canal. Meanwhile, the hair of the beard and mustache, armpits and pubis are dependent on sex hormones.

Experiments have shown that after neutering, hair grows more slowly in dogs, guinea pigs and rabbits and, as a result of lengthening the shift period (in dogs), becomes longer than before neutering. It is known that in animals the administration of testosterone propionate promotes the growth of a deeper hairline, and estrogens retard growth, the hair becomes thin and thinner.

Affects hair growth and food composition. The chemical composition of the hair includes 5% sulfur and pure ash, 20% silicon and 10% iron and manganese. Therefore, an increase in the content of these substances in food in some cases will somewhat improve growth. The systematic introduction of adhesives into the diet in the form of decoctions of bones and meat is a good adjuvant for poor hair growth.

Surprisingly, we are born without even knowing that literally a couple of weeks before birth we were completely covered with hairs. Hair on the baby's body begins to grow even when he is in the womb. Infant fluff (lanugo) is a thin, weak hair that appears in the fetus around 12 weeks after conception and falls out at 40 weeks before the baby is born. These hairs have a protective function.

2. There are three types of body hair

Lanugo or infant fluff, mentioned above, is the first type of body hair. These hairs are very fine, colorless and similar to the hairs we see on the peel. Infant fluff 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 root. The third type is the terminal stage of body hair formation. During puberty, hairs (especially in boys) become darker and harder, 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, have a protective function: they produce sebum, which protects the skin and hair follicle from bacteria. If the hair is removed from the root, the work of the sebaceous glands does not stop, and they continue to perform their protective function. What's more, removing body hair has a definite benefit: the hairs accumulate sebum along their entire length, which can lead to unpleasant body odor. By removing hairs, you solve this problem.

4. Evolution stripped us of our hair, but rewarded us with subcutaneous fat in return

At the initial stages of evolution, the human body, like the body of most primates, was covered with thick hair. However, according to one of the scientific hypotheses, due to the fact that man 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 overcooling, nature has provided us with a layer of subcutaneous fat, which is very thin in primates that are not in contact with water, 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 our subcutaneous fat.

5. Body hair has two main functions.

Body hair is used for thermoregulation. In cold weather, they stand on end to protect us from the cold, and in hot weather, they absorb sweat, like a desiccant napkin. However, as noted earlier, in the process of evolution, we have lost most of the vegetation on the body. Now it is not so thick as 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 they are.

According to research by American psychiatrists, people whose bodies are covered with dense dense vegetation have higher indicators of mental development compared to those who have practically no body hair. Studies have shown that the more hair a person has, the higher their IQ. Surely the people we are talking about in our article 10 most hairy 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 root of a hair is made up of several types of cells, including even muscle cells. These cells are the "culprits" of 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 fact that the hairs on the skin stand on end) can also appear on a dead body.

8. In summer, body hair grows faster

Body and scalp hair grows slightly faster in the spring and summer than in autumn or winter. This is due to the fact that in the warm season, the metabolism in the human body is faster than during cold weather. The rate of hair growth is also determined by the level of hormones in the body. The more male hormones in the body, the thicker, denser and darker the hair on the body will be. Sometimes hormonal disorders can occur in the body of women, as a result of which the body of a woman can 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 aesthetically pleasing, body hair can accumulate a special, subtle odor that subconsciously attracts members of the opposite sex and arouses their sexual desire. In this regard, scientists have established: most often women who do not remove hair in the bikini area become victims of rape, because it is in this part of the body that pheromones (substances that have this very special smell) accumulate most of all. Remarkably, the “chance” of being raped by a woman who does not remove her hair in the bikini area increases in windy weather, especially if she is wearing loose clothing or not wearing underwear.

To have beautiful and well-groomed hair, first of all, you need to know its type. Men, unfortunately, do not pay enough attention to this fact, which is why they part with their hair early.

The following types are distinguished male hair: normal, dry, oily and mixed.

In accordance with this, it is necessary to select shampoo and balm for hair, which will ensure their health and prevent hair loss.

How to determine

Each person can independently determine their own hair type by examining them more closely. If you have problems with this issue, you can always seek help from a trichologist or dermatologist. Male hair types are defined according to several criteria and can have the following properties:

• Dry and oily, mixed and normal;
• Soft or hard;
• Thin and dense;
• Curly or straight;
• Healthy or damaged.

Depending on a variety of factors (climatic conditions, human health, nutrition, and others), men's hair types can vary, becoming drier or oily, weakened or coarse.

Normal hair type

Each type of hair has its own advantages and disadvantages. But the most optimal among all the others is the normal type of male hair. They are quite dense and elastic, have a shiny and healthy look... Normal hair, after washing, retains its fresh appearance for more than 1-2 days. As a rule, owners of this type of hair do not have problems with a lack of volume or electrification. Hair lends itself well to styling and lies well even without the use of styling products;

Greasy hair

This is one of the most common types of hair for men. Already 1 day after washing, the hair becomes unattractive: the curls stick together and lose volume, dandruff appears at the roots. The causes of oily hair in men can be:

• Increased activity of the sebaceous glands, acquired by inheritance;
• Excessive passion for smoked, fried and fatty foods;
• Improper care oily hair: Application of masks based on oils, frequent brushing.

Meanwhile, this type of male hair has two significant advantages: curls are very rarely sectioned and not electrified.

Dry hair

Perhaps this type of male hair can be attributed to the most problematic, but at the same time rarely found among the representatives of the strong half of humanity. Dullness, brittleness, the appearance of split ends - all this can fully be attributed to dry hair type. The reasons for this problem are simple:

• Low sebum production;
• Frequent staining using highly concentrated oxidants;
• Exposure to wind and sun on hair;
• Frequent styling using a hair dryer / tongs, as well as styling products (gel, varnish, hair foam);
• Incorrect brushing or inappropriate comb.

Women are more likely to encounter dry hair, since it is mainly the fairer sex who are prone to frequent dyeing and styling of their hair.

Mixed hair type

Curls, oily at the roots and dry at the tips, are quite common among the stronger sex. This type of male hair is called blended hair. Typically, such hair becomes due to the following factors:

• Frequent washing of hair with shampoo or soap;
• Seborrhea;
• Rare combing.

For people with mixed hair types, it is difficult to find care products, as the curls quickly become dirty at the roots, but the ends remain dry. The ends of the hair can frizz and also have a problem with electrification.

Men's hair care

Men are not fewer women want to look beautiful and well-groomed. Regardless of the type of male hair, any head of hair requires proper care... This is not difficult to do at home. By adhering to the following recommendations, you can give your hair a healthier and more well-groomed look, despite the existing problems:

For normal type

Shampoo your hair 2-3 times a week. Also choose a conditioner balm that is suitable for this type of hair;

For the bold type

Wash your curls daily with a gentle shampoo and once a week with a deep cleanser. Do silicone-free masks 1-2 times a week. Normalize food and drink more water;

For dry type

Wash your hair about once every 7 days mild shampoo with moisturizing ingredients. Refrain from staining, discoloration and perm hair. Regularly apply indelible serums or oils to your hair, and cut split ends once a month;

For mixed type

Wash your hair with shampoo for mixed or normal hair 2-3 times a week, remembering to use conditioners and masks for additional care. If your hair has not been dyed or permed, silicone-containing products are not suitable for you. For dry ends, use moisturizing sprays and serums that don't need to be rinsed off.
