How many hair follicles does a person have? Interesting facts about hair loss and growth
He will try to help you understand this issue so that you can take action in time or, conversely, can calm down and make sure that everything is okay with you.
It will probably not be a revelation to you that hair loses everything, except, of course, for those who have nothing left to lose. This is absolutely a process indicating that the update processes in yours are proceeding as expected. Human body it is designed in such a way that the skin is constantly renewed, old ones die off, and new ones appear in their place. The same applies to, which are part of the protective covers.
This is all clear, but this raises the question: how much hair should fall out normally?, does not become less relevant. A definite answer will probably not satisfy you, because according to experts, the loss of 45 to 170 hairs per day can be considered normal.
This information is likely to confuse you even more, so let's figure out what this figure depends on.
First of all, it is logical to know how many hairs are on your head generally there should be. The question is simple, however, the answer is again ambiguous. The average number, called by experts, is 100,000 hairs. Average doesn't mean right for you. The point is that number of hairs varies depending on many factors. If you take the average European, then, with red hair, he most likely has about 70–80 thousand hairs. If he is dark-haired, then this number rises to 100 thousand. The brown tint adds another 10 thousand hairs to the owner and, finally, blondes are in the lead, for whom the average normal number is considered to be 150 thousand hairs.
It's also worth knowing that not everyone hair follicles function simultaneously. Most of them (about 90%) continue to work honestly and produce hairs, while the rest are “on vacation” - sleeping or preparing to wake up. It is also estimated that approximately 15% of hair is in this stage at any one time, which is where you should start when answering the question of how much hair you personally should lose.
Let's assume that you are a brunette and take the normal number of hairs for you as 100,000 pieces. Let's calculate that 15% of this figure is equal to 15,000. This is exactly how much is in the process of falling out. On average, the duration of this stage lasts a little more than 3 months or 100 days. If we divide all the hair loss by the number of days, we get 150. This will be your hair loss rate per day.
You should also not panic at the sight of a hair follicle that has fallen out along with dead hair. Rest assured, the hair follicle - a cozy nest with a full supply of “food” for a new hair, remains in place. It's probably worth it pay attention to hair, fallen out without a bulb. If, upon closer examination, you see that it is thinning at the ends, then you are most likely dealing not with hair loss, but with hair fragility, and this is a slightly different problem.
The next burning question for most women is whether how long does hair live and grow?. This one is a little easier. Latest Research showed that on average the life of a hair lasts for six months. The growth rate depends on the time of year and even the day. It has been proven that hair grows faster in the warm season, and the same happens at night. If we take the average figure, then hair grows by 0.3–0.5 mm per day, which gives us a maximum of one and a half centimeters per month.
Sometimes it may give the false impression that you have too much hair falling out. In this case, the number of hairs on the comb will be within the normal range, but one look in the mirror will allow you to see that the hair has thinned considerably. This happens if the hair has become thinner. This may also indicate that some hair follicles are “staying late on vacation.” This is quite possible and does not happen very rarely for a number of reasons.
If you notice something like this or the amount of hair falling out does not fit into the given framework, you should seek advice from a specialist and start on time.

People have different types hair. Some people have straight hair, some have curly hair, there are thick and thin, dark and light. Most people dream of one thing: for them to be thick. Therefore, the question arose, how much hair is on the head.
Quantity
The amount of hair is completely individual. If we talk about the average, scientists have found that 1 sq. cm contains from 30 to 310 hair follicles. Most are in the growth stage.
Through mathematical calculations, taking as a basis the area of the head and the amount contained in 1 cm, it was concluded that on average the hairline includes from one hundred to one hundred and fifty thousand hairs.
Anyone can find out the approximate quantitative composition of their hair. To do this, you need to consult a trichologist. He is using special methods will establish the approximate number of hairs that grow per 1 square meter. cm of the head in a particular patient.
It is impossible to name a norm or identify any standard. Doesn't allow you to do this huge amount factors influencing this indicator.
Hair loss test.
Determining factors
There are a huge number of factors that determine how much hair there is on the head, ranging from how correctly it is washed, to genetic disposition and race. The most common factors considered are hair color, gender and age.
Color
The color of the hair is determined by the shape of the pigment granule and the amount of air contained in the hair. There are five main types: blondes, fair-haired, red-haired, brown-haired and brunettes. Gray hair cannot be called in a separate color, since this is simply their loss of pigment.
Blondes and fair-haired people have the highest density of hair per 1 cm. More than 150 thousand hairs grow on their head. Next in descending order are brunettes: they have about 110 thousand, brown-haired people have 90 thousand. Those with red hair have the least amount of hair – about 70 thousand.
This variation is due to different hair thicknesses. In redheads it is maximum: the cross-section is almost 0.08 mm. For brunettes, this figure does not exceed 0.05 mm. For blondes and fair-haired people, the hair cross-section is minimal - no more than 0.04 mm.
Age
A person’s hair grows before the moment of birth, and begins to form in the third month. intrauterine development. 1 cm skin The head of newborns contains about 600 follicles. Gradually this figure decreases due to the increase in hair thickness. By the age of 1 year for each square centimeter There are no more than 400 hair follicles, by the age of 12 there are 320. At the age of 13, a person has the thickest hair, by the age of 30 it has already thinned by about 15%.
Floor
The number of hairs on the head is determined by the gender of the person. The nature of a woman is such that she has more thin skin. Therefore, the weaker sex has almost 10% more quantitative hairstyles. In men, daily hair loss is almost 30% higher. In everyday life, as well as when washing, this is less noticeable due to the difference in the length of the hair.
Height
The structure of human hair is unique. Their living part is hidden under the top layer of skin - the epidermis. On the surface you can only see a part consisting of dead tissue.
There are three main stages of growth. During the first stage, hair grows most actively. In the second stage, growth stops, but nutrition continues. At the last stage, growth stops completely. As a result old hair falls out, is replaced by a new one, and the cycle repeats. Genetic code programmed to repeat it about 25 times during a person’s life.
Scientists have determined that the first stage lasts up to 4 years, the second – no more than 15 days, the third – approximately 3-4 months. Some hairs live up to 7 years. IN percentage more than 90% of the scalp is in the first stage, 1% in the second and about 6-7% in the third. Hair grows most actively in at a young age– from 15 to 25 years.
The growth rate is influenced by many factors: in spring and summer it is higher, short hair grow faster. Proper care, washing your hair in accordance with the rules helps to enhance growth. Scientists have found that during sleep, hair length changes more actively. Normally, hair grows approximately 1 cm every month.

- The record length of hair was recorded for an Indian man; it was about 8 meters.
- Every day, normal hair loss is 90-100 pieces, and new ones begin to grow in place of the lost ones. As men age, hair loss may accelerate under the influence of hormones.

There are people in the world who periodically complain that their hair is falling out. However, they probably don’t know that on average a person loses about a hundred hairs every day and this is considered normal. However, they are sure that they will soon go bald, they begin to worry and wonder how much hair there is on their head? Let's look for the answer together.
To answer this question, you need to find out the color of your hair. So, if he is red, then you can count about 80 thousand hairs on your head. Brunettes have a little more of them - about one hundred thousand, and the leaders are blondes, who can boast of a much larger figure - up to 140 thousand. Why nature ordered it this way, alas, is not known.
The outer part of the hair that we see is called the shaft, and the inner part, which is located under the skin, is called the bulb. Next to the bulb is a follicle - a hair follicle. Based on the shape of the follicle, you can determine what kind of hair a person has: curly hair grows from an oval follicle, and straight hair grows from a round one.
The hair has three layers. The first of them, the outer one, is called the cuticle. It is formed from scaly cells that cover each other. Then, under the cuticle, there is a second layer - the cortex. It consists of dead cells. Also in its composition you can find melanin - a substance that is responsible for hair color. In the center you can see the soft medulla (third layer), which presumably carries necessary elements to the two layers above.
By the way, do you know why your hair is so shiny? It turns out that the natural fatty lubricant secreted by sebaceous glands located in the skin. It is worth noting that lubricant also performs protective function. However, if there is too much lubricant, which happens, for example, when hormonal disorders, then the hair becomes too oily. If the secretion is not enough, then, accordingly, dry.

There are so many things our hair can’t stand, and haircuts, and dyeing, and curling, and straightening, and braiding, and extensions, and exposure to cosmetics... And with all this, we want our hair to grow well and not fall out.
There are many interesting questions and answers, facts about hair loss and growth and this once again emphasizes that this problem very relevant and of interest to many.
Interesting facts about hair growth and development
Some people think that the hair on the head grows continuously and should fall out very rarely. Without going deeply into the structure of the hair, we can say that it consists of a bulb or hair follicle with a papilla, which is located under the skin, and the hair itself or the hair shaft.
Three stages of hair development
Scientists note 3 stages of development in the life of hair:
Anagen – stage of intensive hair growth. The older a person is, the shorter this period becomes. During the anagen stage, the hair follicle grows, melanin cells are actively formed, which produce hair coloring melanin pigment.
Hair in this stage grows at a rate of 0.4-0.5 mm per day, and the duration of the anagen stage lasts from 2 to 10 years, according to research by the German scientist Trotter.
Catagen - an intermediate stage of hair development, between its growth and the resting phase. At this stage, gradual atrophy of the papilla on the hair follicle occurs, and nutrients enter the hair through the papilla.
As nutrition stops, follicle cells stop dividing and growing and eventually become hard and keratinized. The catagen stage lasts only a few weeks.
Telogen - the resting stage of the hair, when the hair follicle is freed from the old hair and it falls out. When washing our hair, when we actively massage the scalp and when combing, telogen hair falls out faster. The resting stage of the hair follicle lasts up to 3 months.
During a person’s life, hair falls out and grows again, that is, these stages of hair development are repeated up to 25 times.
Does hair loss depend on frequent washing?
Sometimes we notice with horror that when we wash our hair, a sizable bunch of lost hair is collected. And a suspicion immediately arises: maybe this is due to frequent washing of your hair? Of course not.
When you wash your hair, it is no longer living hair that falls out, but telogen hair. Healthy hair Washing your hair doesn't hurt. Absolutely normal occurrence A daily loss of 50 to 100 hairs is considered. Frequent contact with a comb, shampoo, or water does not cause hair loss.
There is an opinion that bald men are loving, is this true?
Once upon a time, about a hundred years ago, Dr. James Hamelton theoretically proved that baldness in men early age involved male hormone testosterone, on which it depends increased activity men.
Modern medicine has proven that baldness (alopecia) is associated not with the level of testosterone in the blood itself, but with the sensitivity of the receptors located in the hair follicles to a testosterone derivative - dehydrotestosterone.
And if the amount of testosterone in the blood is below the level established norm, hair loss may still develop. And the development of this process depends on the degree of sensitivity of the hair follicle receptors to the testosterone derivative - dehydrotestosterone.
And the sensitivity of these receptors is determined by hereditary factors. It turns out that it is not testosterone that is to blame for early baldness in men and their androgenetic alopecia, but heredity.
Does hair really get thicker with frequent haircuts?
There is a lot of talk about the fact that haircuts affect hair thickness. What's really going on? Hair grows from follicles (hair follicles), and how many of these follicles nature has placed on your head, no haircut will increase their number.
After a haircut, if the haircut is short, it seems that the hair has become thicker. This appearance of density. After all, during cutting, the tip of the hair is flattened, thereby creating the appearance of increased volume at the ends of the hair.

You've probably heard the opinion yourself that frequent use of a hair dryer leads to increased hair loss. With frequent drying of hair on a hot mode, the hair becomes dry, its external beauty, shine, silkiness are lost, it becomes brittle and splits.
Proper use of a hair dryer cannot cause hair loss. First you need to dry your hair with a towel and then use a hairdryer. Do not bring the hair dryer close to your head, a distance of 15-25 cm is considered optimal, it is better to guide your hair with your hand rather than with a comb, read: causes of hair loss.
Is baldness hereditary?
With early hair loss in men, the cause of androgenetic alopecia is often heredity. Statistics say that in only 15% of cases, alopecia is transmitted on the paternal side, and in 70-75%, the predisposition to alopecia is transmitted on the maternal side.
How long does the hair on your head last?
How long will hair grow if you don't cut it? At the beginning of the article, 3 stages of hair development and life are described. Hair cannot grow indefinitely; it all depends on the stage of hair development.
The lifespan of hair depends on many reasons, including hereditary factors, health status of the body, nutritional balance and other factors.
Over the course of a person’s entire life, hair manages to “go through” about 25 complete cycles of growth and development. It was noted that the thickest and long hair in a person at a young age from 15 to 18-19 years.
After, every next life cycle the hair becomes shorter, and the hair itself changes, also becoming shorter and thinner.
The average duration of one hair growth cycle is approximately 5-7 years, although it has already been noted that they live up to 10 years (this depends on many reasons).
Constantly wearing a hat on your head will increase hair loss.
If a cap or hat does not compress the head, if it is made from natural materials and does not interfere with the air exchange of the head, then hats can be worn without danger to the health of the hair.
It is important that the headgear does not put pressure on the head and does not disrupt the normal blood supply to the head.
