Since its inception, each follicle passes repeating cycles of active growth and peace. The relative duration of the phase of the cycle varies depending on the age of the individual and the area of \u200b\u200bthe skin.
Active hair growth. In this phase, an active division of the cells of the matrix occurs, a hairpin is formed, an inner hair bag, melanocytes at the base of the papillae begin to produce melanin (therefore, the bulb of the hair in this stage has a darker view during microscopy than the bulb of the telogen hair). The average duration of this phase from 2 to 5 years (1000 days for memorization).
This is a transition phase. The mitotic activity of the matrix is \u200b\u200bgradually stopped and the follicle enters the Cathagen phase ending within a few days. The terminal part of the hair becomes thickened and deprived of the pigment. The lower part of the follicle is shortened, the inner root vagina disappears, so the telogen hair under the microscope is always smooth, it does not hold it. Further, after 10 days, the follicle enters the telogen phase.
It is a phase of resting the hair cycle. The flask of the hair (with a unplanned bulb) is held in the follicle due to the intercellular compounds and can be maintained for several subsequent generations of hair.
Normally, the duration of the anagena phase in each person is genetically determined and takes from 2 to 5 years. The average duration of anagena is easily remembered as 1000 days. The duration of the teleogen phase is approximately 100 days.
Thus, the ratio of anagen hair to telogen is approximately 9: 1 (the hair in the Cathagen phase due to the short-term period is not taken into account.)
In average, the population of the follicles of the scalp is 100,000; Blondes are more, red-haired smaller. Thus, a person loses about 100 hair daily.
Density hair follicles Children of the first year of life accounts for 780 / sq. M., and by 30 years decreased to 615. Between the 30 and 50 years, this number reaches 485.
Methods of microscopic examination, which allows to estimate the ratio of hair in the phase of anagena and telogen.
The execution of the trichogram allows you to identify the type of alopecia, the activity of the process, assess the effectiveness of the treatment carried out.
Normal relations:
In children, the ratio of a / t \u003d 90/8
In men: a / t \u003d 83/15
Women: A / T \u003d 85/11
Dystrophic hair in the anagena phase is 2-3%.
The percentage of hair in the Telogen phase increases with age and the highest in the bobbin area in both sexes.
The growth rate of hair is 0, 35 mm. On a day in the field of patterns and temples, the hair is somewhat faster in these places in women.
The length of each hair depends on the duration of the anagena phase and the rate of hair growth rate, which is due to genetically.
Androgen
(Men's sex hormones) increase the growth rate and diameter of the hair in androgen-dependent areas, such as beard. However, on the head of people predisposed to genetically determined alopecia, androgens reduce the diameter of the hair rod and growth rate, as well as the duration of the anagena phase (polycystic, hyperplasia of the adrenal glands, state after pregnancy).
Estrogen
(female sex hormones) slow down the growth rate of hair in the anagena phase, but lengthen its duration (pregnancy)
Tyroxin
(hormone thyroid gland) Accelerates the beginning of the anagena phase in resting follicles, and cortisone slows down this process.
Contrary to widespread opinion, nor shaving, nor sunlight have no effect on the growth rate of hair (experience in 1970, shaving hair from one foot for 5 months and the subsequent comparison with the hair of the control foot is not marked by any differences in the mass, diameter and hair growth rates.)
Dandruff is characterized by the appearance of a plurality of small loose scheels on the skin of the scalp, more in the occipital-dark area. Most often, it is a companion of seborrhea, but may be associated with violation exchange processes In the body, incorrect hair care. Some scientists consider dandruff as an infectious disease.
Anti dandruff is successfully used by hot infusion of floral baskets Blue vasil on vinegar and water (1 tablespoon of raw materials on 200 ml of table vinegar and 200 ml of water), which rubbed into the skin of the head daily in the evening for 15 20 days.
Remove dandruff and strengthen hair helps shampoos "Seborin", "Sunshine", "Chamomile", "Shampoo with Henna", "Raffil".
Favorable impact on the elimination of dandruff and itching birch tar. 3 5 hours before washing hair in the head of the head rubbed a mixture consisting of 5 10 g of birch tar, 10 20 g castor Oil and 100 ml ethyl alcohol. The people for the treatment of dandruff is widely used by freshly squeezed nasturtium juice, which lubricates hair 1 time per day. Such actions have the leaves of a parsnik sowing.
Bulgarian medicine advises dandruff garlic, onion, pyrzya, cheeritz, freezing plowing, pine(The essential oil of pine needles is included in the preparation of PIT).
Inside it is recommended to take vitamins A and groups B. Preventive activities should be aimed at eliminating the causes that contribute to the appearance of dandruff, the use of individual comb, brushes and headdresses, correct care Haired.

Hair for many people is an important element affecting the correct perception of self, good health and self-esteem.
For some, their loss is the cause of depression due to violations in relations between people and problems with the adoption of their own appearance. In most cases, the baldness concerns people aged, but sometimes it happens that young people also affect this disease.
Anaged baldness It is an example of hair loss, occurring in young people.
Density, thickness and amount of hair are an individual feature of each person, which is subject to significant fluctuations and depends on many factors:
Hair growth asynchronous, which prevents the simultaneous loss of all hair.
Hair growth cycle is divided into several phases:
Baldness occurs when day loss of hair It is more than 100 and persists within a few weeks. Hair can fall out on the entire surface of the head or only with limited places, sometimes it also concerns other parts of the body (for example, armpits, eyebrows, eyelashes, beard in men).
Anaged hair loss does not cause, as a rule, sustainable baldness, and the hair is growing independently after termination harmful factor. However, there are medicines that can be useful to treat baldness through acceleration of hair rustling. For example, minoxidil.
The hair on the human body grows throughout life, but everyone is different. Someone quickly, "as on yeast," and someone has to unsuccessfully grow spit to the belt for many years. The speed of the process depends on many factors: heredity, health, lifestyle, environment. It depends even on age and gender. Thinking over how the hair on the head grows, many mistakenly believe that every hair is drawn continuously until it falls. Meanwhile, 3 phases of development are spent on its entire life cycle.
Beautiful, well-groomed hairstyle helps to create a pleasant first impression when meeting. But the hair is important not only by its aesthetic function. They protect the body from the harmful effects of the environment, maintain the optimal temperature balance. The hairproke begins to form in the womb. Then this gun is deprived of pigments. The coloring agents occur in the structure later, before the appearance of the baby.
By the way. Folk sign Approves: heartburn during pregnancy - a sign of the birth of a child with a thick, abundant chapel. Scientists refute the speculation, explaining: the amount, color and structure of the hair are laid at the genetic level.
Problems with strands violate the optimal balance.Healthy, shiny hair is often called "alive." However, the paradox lies here: just the outer part (rod), for which the man and women are so carefully followed, consists of dead cells. Live - the one that is hidden under the skin and is responsible for the structure, the rate of reflection of the curls. It is called a bulb or root.
The hair rod is formed from three layers:
Interesting fact:a person has about 100-150 thousand hairs on the head. The most thick chapelurs boasts natural blondes and blondes.
Follicle gets food from blood system Through the dermal papilla - an important element of the entire structure. If he dies, the entire hair rod dies.
The form of the follicle depends on the appearance of the curls:
With the functioning of the follicle associated phases of hair growth on the head.These are the stages of the life cycle, repeating for each hair from the moment of birth to natural dropping.
Important for hair beauty have sebaceous glandspassing next to the follicle. Their incorrect work makes a normal dry lap or, on the contrary, fat.
The cyclical growth of strands is often compared with the development of plants planted in the ground.In the spring there is a layout of the base, the formation of roots. In the summer, the time of active growing is possible due to proper nutrition. Autumn - a period of slow, gradual dieting. A similar situation with the chapel.
Scientists allocate such repetitive hair growth stages:
After that, everything starts with the anagena phase again, when in the same follicle first forms, and then the new hair grows. The cycle is repeated about 25 times.According to other estimates, from one bag of a person in a whole life grows from 20 to 30-40 hair rods that replace each other.
By the way. The look of the whole hairstyles depends on the growth stages. Get a braid below the belt is easiest in just young age, because with each new cycle, the strands are in short. After 30 years, the speed of their rustling slows down.
The first hairs are formed on the head of a non-born baby about 4-5 months of pregnancy.After the appearance of the crumbs on the light of the gun, 1-2 months falls out, new strands are growing instead. Often phenomenon among children of the first year of life - rolling when they are formed on the head.
Most often - from the bottom of the nape, because most of the time the newborn spends lying on the back. Prevent the process will help regular baby turning on side, tummy.
If the hair in the newborn grows badly, the parents are worth:
There is a long tradition of shaving a child to sleep to the first birthday. It is believed that this contributes to the appearance of a more thick hair cover. However, pediatricians, trichologists, hairdressers are unanimous: Shaving does not bring the desired effect, because the number of follicles does not increase.
But this procedure helps to remove the first cannon, it is better to make crusts from the scalp. The hair after that will grow more evenly on all areas. Actually, if a child has never been cutting to a year.
Girls up to 3 years old should not be braid tight pigtails: they may arise for stars in the field of the temples.For this reason, many parents prefer to make short haircuts. Children's curls require more tender care than adults. Fully hair cover will be formed in a child by 11 years.
The rate of rustling depends on different factors: heredity, health status, the number of years of lived and even sex. Scientists came to the conclusion that in women this process is slower. The duration of the "life" of the hair rod is different. On the head of men, the strands are updated every 2 years, the ladies - in 4-5 years.
Interesting fact:it has been proven that the inhabitants of Asia, the lambers of the chapels are faster. Europeans on this indicator ranked second.
Beautiful sexes need to carefully monitor the hormonal background.Pregnancy leads to violation, even menstruation, climax. As a result, the growth of hairs can be braked.
Also, the process of rustling worsen:
Rides on the head in men grow at the same speed as a beard. After 40 years, vegetation on the face increases more actively, but scientists have not yet managed to explain this fact.
Also men and women it should be remembered for other reasons that stop natural reflection:
Attention! If a person is not inclined to baldness, each new hair coincides with the previous over the thickness, length, other parameters. Snacks may notice that over time, the strands become thinner, light, worse grow. With each next generation, healthy curls are degraded, turning into a colorless gun. Natural process becomes older.
The hair on the head is growing continuously, but at different speeds.
Additionally, this is due to such factors:
The greatest chances of growing the most long braid comes to age from 14-17 to 30 years.
If the hair grow slowly than you want, review the lifestyle, food. Refuse bad habits, adjust the day. There is a lot of proven ways to influence the growth of the chapels, using professional funds, folk recipes.
The action of many cosmetics reduces the teleogen phase, awakens the "sleeping" roots or provides additional nutrition to follicles. Using similar preparations, do not be lazy to learn about efficiency, contraindications from instructions, reviews, training videos. Beautiful hair is not only a gift given from birth, but also wealth entered over the years with competent care.
Trichologist about hair growth. Is it possible?
As far as the hair is growing per day.
Well-groomed hair is a dream of any weak floor representative. Watching a lot of time and effort to different styling, curling and painting, many girls forget that the key to the beautiful hairstyle is a healthy chapel. To make it such, you need to learn, hair, what is the cause of pathological changes and ways to eliminate them.
Each hairs includes several elements. Its visible part is a rod, which consists of non-living cells filled with keratin. In the thicker of the scalp (at a depth of about 2.5 mm) there is the part of the hair, which determines its appearance - the root. It consists of a variety of living cells that are continuously divided. This process provides a hair growth. It is impossible without the participation of fabrics located near the root. All together they form the hair follicle, from which the nervous end is moving. The structure of the hair on the head is such that damage to this end leads to a complete dying of the root without the possibility of its further recovery. The work of the sebaceous glands next to the follicles also has a great influence on beauty. If they are excessively large, then the skin of the head becomes fat. The underdevelopment of the sebaceous glands leads to its dryness. Also in near each hair is located muscle, providing its rise.
Good follicles provide fast growth Hair and a significant duration of their lives. However, the appearance of the chapels is also determined by the status of the rod. The structure of the hair in the context shows that its visible part includes the following layers:
The structure of the hair determines the various phases of his life. They cyclically replace each other and depend on the degree of fission of root cells. The lifespan of hair can be divided into the following phases.
Most hair falls out during the period in the televisional stage. Some, however, are preserved until the very beginning of the outcast phase. At the same time, they fall out at the moment when the newly appearing hair rod pushes the old one.
Growth phases in the same way as a human hair structure, determine the appearance of the hairstyle. Long curls, for example, the easiest way to grow at a young age. This is due to the fact that each hair has about 25 cycles of life, with each of which it grows less and becomes more subtle. In addition, after 30 years, hair growth is gradually slowed down. Up to this age, they grow about 1.5 cm per month.
There are a number of reasons that can cause a slowdown in growth, hair loss, negatively affecting them. appearance. These include:
In this way, beautiful hair - a sign of a healthy and workable organism. Dull and brown curls are often reflected from different chronic diseases and pathological conditions with which it is necessary to fight first.
Very often, the human hair structure and the duration of the outline phase change in the worse Due to the lack of vitamins and trace elements. The hair becomes dry, brilliantly deprived of a shine. In this case, it is worth reconsider the diet or try to fill the lack of vitamins with special additives. When they choose, it is necessary to pay attention to the presence of the following components.
Improving hair structure is possible and subject to some simple care rules.
The structure of the hair is to some extent an indicator of the state of the body as a whole. Therefore, if, subject to the diet that admits the necessary vitamins and trace elements into the body, and they continue to fall out and look lifeless, it is worth contacting the trichologist. You should not try to cope with the problem yourself, because it can be a symptom of any chronic disease. Trichologist will help to deal with the causes of pathology and, if necessary, will send to other doctors for consultation.
There are 3 phases of hair growth on the body: anagen, catagen and telogen. After shugaring, as well as after any other way of epilation, the hairs can grow unevenly. When one hairs grows, others are at this time under the skin.
Before starting the process of sugar depilation, this moment must be voiced by the Client. You can even show him "black dots" - it is a hairs that are selected on the surface are the first.
If a client, waiting for the ideal result from shugaring, will not be aware of hair growth features in different phases, it will be disappointed. Therefore, the master must simple language Explain to him the process of hairs activity.
There are three phases of hair growth: anagen (stage of active hair growth), Catagen (regression stage) and telogen (recreation stage).
The hairs grow out of living follicles, which are located under the skin. The follicle includes more than 10 varieties of tissues and cells involved in the formation of a future hair.
Important! In total, a person has about 50,000,000 hair follicles. Up to 40,000,000 of them are on the body.
At first, the follicle grows, then regnets, then it "falls asleep." Life cycles of follicles located on the body may not coincide. Depending on the growing stage, from different parts Bodies grow hairs of different lengths.
The phase of active hair growth is called angen. It is a stage of active division of hairs cells. The average duration of an agenic stage is 2-6 years old (on the head) and several weeks - on the body.
In this phase, there is from 81 to 91% of the follicle. The growth of hairs is 0.7-1.2 cm / 30 days: it all depends on which ethnic group owns a person. Individual features of the body are also important. As the person agrees, the duration of the antenage phase is reduced.
The stage of growing hair follicle on the body varies from several weeks to several months. Those hairs that grow up after Shugaring, until a certain point, simply "slept".
The effectiveness of shugaring depends on what state was at that time the hair cover was at that time. Considering varying life cycles Hair follicles, some people find enough depilation no more than 1 time / 30 days.
The phase of the regression of the hair is called Catagen. This is an intermediate phase of hair growth. It begins when the hairs gradually disconnects from the hairpad and ceases to fed - That is, it stops obtaining the necessary nutrients.
For the catagena phase, it is characterized to stop the production of pigments and division of follicle cells.
The follicle itself becomes shorter, and its base begins to shift to the surface of the skin. The duration of this phase is 14-20 days.
The recreation phase is called telogen. At this time, the hairs do not grow, and hold in the skin. The duration of the phase is about 90 days. Normally, in this period, it is at the same time from 6 to 21% of the follicle.
When the telogen stage is completed, the actively division of the stem cell cluster is observed. After that, in the new antenna stage (the more accurate name of the stage - the early antensen) forms a new hairs.

Depending on the body part, the hair growth stage varies. On one part of the body, the hair is faster than the degree of activity, to another - slower.
The activity of the hairproof, depending on the body part, looks like this:
Shugaring affects the hair growth stage as follows:
If depilation was conducted in the stage of rest, the following hairs will be thinner. If during the shugaring, it is removed that the new hairs has been removed, the new follicle is not formed for about 2 months.
Sometimes the client detects the abnormal hairs a few days after sugar epilation.
If the shugaring procedure was carried out qualitatively, the appearance of new hairs is determined by the fact that at the time of depilation, some of them were in the Telogen phase. This is explained by the fact that at the time of shugaring under the skin, new hairs can start growing. It is he who goes to the surface a few days later.
In the antenage stage of the hair is powered by blood vessels Pack. Therefore, when the hairs are removed in the anagena stage, blood dews appear. Its appearance is due to the fact that during the depilation of the hairs, drunk from the papilla. It is for this reason that a small amount of blood is distinguished.
Important! If the shugaring procedures become regular, then over time the blood dew will not appear anymore.
Sugar hair removal cannot remove the hair for one growth stage. The main task of a sugar epilation specialist is the removal of "young" hairs.
Further goal is "Capturing" and the removal of the same hairs. Only in this case can be ensured as high quality and long effect. The time between sessions is extended.
Hair removal into one stage - the task is impossible.
A person has three phases of growth in the body of the hair: Anagen, Kathagen and telogen. First, the hair is actively powered by, there is an arrangement of its "trunk" and developing melanin.
Then he dies and falls out. Then the time of rest is coming, which is characterized by the fact that nothing happens to the hail. Then there is a new hairs.
From the first video, you will learn how the hair growth phases can affect the result after Shugaring. In the second video, the Depilation Master explains why the hair is not even evenly.
