Why do people s armpits grow hair?

The history of human evolution is recognized as the evolution of human beings from apes to humans. The original full body hair was gradually replaced by clothing, but a lot of it has been retained. If Darwin's theory of evolution is not wrong, then according to the principle of natural selection and survival of the fittest, all parts of human body have their own necessity and function.

Let's just say that the hair on the person, the hair knows the sweat cooling and protection when you look at the name, and the hair is the same, and there is an extra beauty, and some people even ridiculed: the head can be broken, and the hairstyle should not be messed up. The nose hair acts as a filter, blocking the dust in the air from inhalation.

But the armpits belong to the hidden parts, what is the hair in it? It's not aesthetically pleasing and doesn't seem to have any other purpose. Driven by curiosity, I looked it up on the Internet, and I didn't think that there were many people who were bored enough to study this.

Now I have seen it, and the armpit is also called the armpit (bird's nest?). Natural hair is called axillary hair. How did it come about?

It turned out to be the result of androgens secreted by the adrenal glands. This androgen is not exclusive to men, but also to female compatriots, so both men and women have armpit hair. Since it is hormone-induced and belongs to secondary sexual characteristics, it is just a sign and has no substantive effect, anyway, I didn't find it on the Internet, hehe.

But if you think about it, it should also play a protective role, at least when the arm swings, it avoids direct friction. Armpit hair is dispensable, even if it is shaved by women who love beauty, men who need it can also shave off, hahaha.

Hair is evolved by humans, and if the arm moves, it can generate friction and generate heat. There is hair under the armpits, which can reduce friction and avoid direct friction, and at the same time is conducive to heat dissipation.

The claim that armpit hair can prevent bacteria is a bit far-fetched.

Main function: anti-friction, ventilation and moisture dissipation.

It's just a hair that hasn't degenerated in the process of evolution, and it doesn't have any effect.

It's a natural physiological phenomenon and there's no why.

1 Shave off, buy a lady's razor, shave it off when you come back to take a shower, make some soap foam under your armpits, shave, and finally rinse it with water, and come out to apply some lotion.

If you have a lot of Mido, go buy an electric shaver for Philips women, shave, it is better to use, and you can go for leg hair or something.

If you have money, or don't want to spend too much money on hair removal, you can buy a Gillette men's razor, the supermarket has it, there is a 10 fast money, super cheap, very easy to use, shaved well and clean, recommended by my classmates in high school, hehe.

2 Beeswax, buy a bottle of beeswax, remove the hair yourself, or take it to the beauty salon and ask someone else to help you get it, apply the beeswax evenly and thinly on the **, and then stick the distributed paper on the beeswax, paste it, follow the direction of the hair, tear off the paper quickly, the hair will fall off, it hurts, so the sooner the better.

Ice can reduce pain, so it is recommended to apply ice before doing beeswax hair removal**, the paper can be washed with water and can be used repeatedly.

Generally, when you buy it, you will be equipped with a bottle of hair suppression lotion, which is to repair and soothe ** after you have finished hair, and at the same time can inhibit hair growth.

After using beeswax, you must clean it**, the residue of beeswax will cause folliculitis, so wash it clean and then apply lotion.

3 Plucking, thinking that I have a classmate with less armpit hair, she took the kind of clip that plucked the eyebrows, and plucked it herself in the mirror, it was a little painful at first, but it didn't hurt to pull it out a few times, and after pulling it out for a while, she didn't grow hair under her armpits, and recommended us to do this, but I was really afraid of the pain, so I didn't dare to try it.

4 Hair removal cream, apply it and wait for a period of time to wipe it off with paper, the hair will fall off, and you can clean it**.

But this thing is not recommended, because I have tried a lot, it doesn't work, the hair is not clean at all, and the razor is not easy to use, and there is a very strong chemical smell, it smells very uncomfortable, and it is too long to wait, and it is not cleaned in the end, and it is not easy to use at all.

I also have it, but I can't use a knife to scrape, I can only use depilatory cream or go to the hospital, it's necessary to get more, it's okay to be rare, it's normal.

It's normal, don't shave it, or it will grow longer and more, darker and harder, unless you shave it whenever you have time, or it will be ugly.

It is normal and does hair removal when I do not want it

Normal. You can use a depilatory cream or go to the hospital.

Let it grow, normal, you're growing! Congratulations.

The most effective way is to use a plucking one, and it will hurt if you don't give it. It can be managed for about a month. The second is the depilatory cream, which does not feel anything, but new hairs will grow within a week. If possible, you can go to a cosmetic hospital for hair removal surgery.

Shave it, if you're a man, it's better to keep it masculine, and for girls, shave it, look good, clean, and tidy.
