What is the reason for having a lot of pubic hair? What are the benefits of having a lot of pubic hair?

We know that after people reach adulthood, due to the development of secondary sexual characteristics, many parts of their bodies begin to change, the most obvious of which is the growth of pubic hair. So what is the reason for the growth of pubic hair?

Causes of excessive pubic hair

Human hair is divided into two parts: the hair shaft and the hair root. The hair shaft is the part exposed outside the skin, that is, the visible part of the hair; while the hair root is the part buried in the skin, which is the root of the hair and is wrapped by the hair follicle. At the same time, the hair follicle plays a role in protecting and nourishing the hair. When people treat the hair on the surface of the skin, it will not affect the hair follicles hidden deep in the skin, and thus will not have any effect on the condition of the hair.

In fact, the amount, thickness and density of a person's hair are mostly determined by their genes and hormone levels. A person's genes determine the color of their hair and the growth of their hair. In a family, the growth of hair is generally the same, which also shows that male baldness is closely related to family genetics.

The effect of pubic hair

In the primitive times when humans did not wear pants, pubic hair played a protective role in protecting the vagina, preventing the invasion of foreign objects and germs, and maintaining hygiene. In sexual life, the main function of pubic hair is to reduce mutual friction during sexual intercourse and prevent the raised mons pubis from being damaged. In fact, during sexual intercourse between men and women, the male's pubic hair is enough to reduce mutual friction during sexual intercourse and prevent damage to the mons pubis. In modern society, the dense pubic hair covering the vulva keeps the vulva in a warm and humid environment, making it a breeding ground for mold, trichomonas, pubic lice and various pathogens, which is not conducive to the hygiene of the vulva.
