Everyone has hair on their body, but everyone's hair is different.
Some hairs and bodies coexist peacefully, no more, no less.
And some hairs are very "naughty", focusing on a conspicuous growth.
For example, some girls find that thick and black hairs suddenly appear on their stomachs.
Although it can be covered, it is uncomfortable to look at yourself.
I want to figure out the principle, but I'm too embarrassed to ask around.
Then let's give girls a special science popularization today! Clause.

3 reasons for belly hair.
There are two types of hair follicles on our body: terminal hair follicles and vellus hair follicles (i.e., hair hairs).
The hairs they grow are slightly different: the terminal hairs are coarse and long; The vesicle hairs are short and thin.
If there is a slender and lightly dyed, shaggy vellus hair on the belly, it is a normal physiological phenomenon.
But if the fur here is dark and coarse, it could be the following:
The hair follicles on the stomach are more sensitive.
Androgens are known to make fur darker and thicker.
But there are about 2 million hair follicles in each person's body, and we can't guarantee that every hair follicle "feels" androgens.
As a result, the hairs that grow out of these hair follicles can be divided into non-sexual hair, hermaphroditic hair, and sexual hair according to their sensitivity to androgens.
Non-sexual hair: As the name suggests, it is hair that has no gender, both men and women, such as eyebrows and eyelashes. Maverick does not rely on androgens to stimulate development.
Hermaphroditic hair: such as **, armpit hair. I feel a little bit about androgens but not much, and other sex hormones can also stimulate their development, and it is more common in girls.
Sexual hair: such as beard, belly hair, chest hair. Very dependent on androgens, it is necessary to thrive.
The hair on the small belly is a type of sexual hair.
Under normal circumstances, boys secrete more androgens, and the hair on the small belly will only appear on boys.
However, due to the lack of androgens, the hair follicles are not stimulated enough and rarely grow thick and black belly hair.
However, some hair follicles just don't follow the usual path, with a genetic mutation, double their sensitivity, and only need a little androgen to stimulate them to grow wildly.
After all, there are millions of hair follicles, and how many mutations are allowed?
Hair follicles are messed up with hormones.
If the hair on your belly is not born thick and dark, but grows slowly over a period of time.
So please recall, have you often stayed up late to watch dramas, had an unhealthy diet, and had a lot of mood swings recently......
These bad habits can raise the level of androgens in your body, making not only the hair on your belly grow thick and dark, but also the hair on your arms, fingers, and lips.
In addition, pregnancy can also increase hormone levels.
Androgens, estrogen, and thyroxine, which affect hair growth, are all elevated, so many pregnant women find a sudden outbreak of belly hair after the second to fourth month of pregnancy.
However, fortunately, after giving birth, the hair will fall off on its own as the hormones fall back.
There is a special illness on the stall.
There is a special disease, both men and women, once they encounter it, they will grow crazy hair, it is hirsutism!
The most common cause of hirsutism in girls is polycystic ovary syndrome, which accounts for 70% to 80% of cases.
If left unattended, it will lead to menstrual disorders, obesity and ugliness, and even infertility. Clause.

Can the hair on the belly be shaved.
If the hairs on the small belly do not affect life, it is not recommended to shave them.
* The bacteria on the surface are mainly located at the root of the hair, and simply shaving the hair on the surface will not only not be clean, but the hair will grow back and will cause different degrees of damage and bacterial migration.
In addition to this, the hair of the small belly also has its own use:
It acts as a "cushion" between clothing and stomach to reduce friction and itching discomfort, and also has a built-in sun protection effect to prevent mosquito bites.
Those sisters who don't have any diseases and are pure sisters with a lot of body hair can also try to reconcile with these little hairies, after all, the role of others is not small.
There is no definition of beauty, you don't have to care about the eyes of others, as long as you are healthy!
