The role of black hair in girls' private parts

People say that girls change a lot when they grow up, and there is some truth to this. When a woman has her first menarche, it means that her ovaries have begun to develop. The ovaries secrete three major hormones, among which estrogen receptors are the most widespread in the human body and have the greatest impact. Black hair also starts to grow in the private parts, which is also called pubic hair. The amount of pubic hair is also affected by hormones. Some girls may feel shy and uncomfortable, but this is normal. There are many benefits to pubic hair.

Female pubic hair growth stages: Pubic hair is a woman's secondary sexual characteristic. During female puberty, there are two more prominent developmental characteristics: one is breasts, and the other is the growth of pubic hair. The growth of female pubic hair is divided into six stages:

In the first stage, before the age of 10, there is no visible pubic hair.

The second stage, around 10-11 years old, is when long, soft pubic hair grows sparsely and is slightly curly.

The third stage, 12-13 years old, the pubic hair increases and gradually becomes curly, coarse and black.

Stage 4, 14-15 years old, pubic hair expands to cover the labia.

The fifth stage, 16-17 years old, the pubic hair expands to the pubic area and becomes adult type.

Stage 6: At the age of 18, the pubic hair is distributed in a typical inverted triangle shape to the inner thighs.

The function of pubic hair: It is not useless, but grows to protect our body. Pubic hair can absorb the sweat and mucus secreted from these parts and dissipate them around, which is beneficial to health. During sexual intercourse, it can also increase the pleasure caused by friction on the external genitalia. In addition, pubic hair also has the function of keeping warm, protecting the normal survival temperature of sperm and eggs! In addition to being a sexual characteristic, pubic hair can also reduce friction and pain caused by rapid movements during sexual intercourse. In addition, the sweat gland ducts in the human pubic area are relatively large and abundant, and the amount of sweat is high. In addition, the hidden area is prone to poor ventilation. The presence of pubic hair can play a role in "ventilation".

Pubic hair hygiene: Among the diseases related to pubic hair, pubic lice is one of the more common ones. Generally speaking, pubic lice can be contracted through contact, whether it is sharing underwear or using a quilt. Therefore, if you want to avoid pubic lice infection, you must pay more attention to basic personal hygiene. If you are unfortunately infected with pubic lice, the best way is to shave your pubic hair to cut off the space for pubic lice to grow. In addition, if the underwear is not chosen properly, it will cause unnecessary pulling on the pubic hair, which may cause symptoms of inflammation of the hair follicles and the growth of small nodules. Tip: Although pubic hair is located in a private area and not many people usually do special trimming or care for it, its importance cannot be ignored. While we usually pay attention to hair, eyebrows and other hair, please do not ignore the hygiene and health of pubic hair.
