Is it normal for men not to have armpit hair?

Armpit hair is the hair that grows under the armpits. Normally, in China, armpit hair begins to grow gradually between the ages of 12 and 15. The growth of armpit hair is the same for both men and women. In most cases, boys have thicker armpit hair than girls. But there are exceptions to everything. There may be some boys around us who do not grow armpit hair. In theory, armpit hair is the result of the secretion of androgen by the gonads. So for boys who have armpit hair, is this physiological phenomenon normal?

Human hair is divided into two categories. One category is not affected by sex hormones, including hair, eyebrows and eyelashes; the other category grows gradually under the influence of sex hormones, such as pubic hair and armpit hair. Human pubic hair and armpit hair grow under the stimulation of the androgen testosterone. Armpit hair usually appears around the age of 14. If pubic hair and armpit hair have not appeared by the age of 18, it is called pubic hairlessness and armpit hairlessness.

The reasons can be roughly divided into two categories: one is that the hair follicles in the armpit skin are insensitive or unresponsive to testosterone, so even if there is a high concentration of testosterone in the body, pubic hair and armpit hair will not grow. This kind of people generally will not affect their sex life after marriage, and they can still have children. Growth and development have basically been completed, and male sexual characteristics exist, which means that there is no big problem with androgen in your body. The reason why armpit hair does not grow is that the number of hair-growing receptors is small, so there is no excessive hair growth. This is not a big problem as long as the androgen level is normal.

The other type is caused by congenital diseases. In addition to the lack of pubic and armpit hair, the patient often has other secondary sexual characteristics that are underdeveloped, such as short stature, no menstruation, and childish appearance. In this case, you should go to the hospital for examination and treatment.

Lack of armpit hair is also related to genetics. It is normal for men to have no armpit hair. Many people will have a series of conditions such as sparse armpit hair or no armpit hair. No special treatment is needed. It is normal and don't worry. Of course, if you feel that you have less hair, you can also go to the hospital for transplantation. Don't worry.

Finally, you can also use ginger to wipe the area for a longer time. Go to the gym to make yourself stronger and have more hormones. Eat more fruits and vegetables, and eat more foods such as pork loin. A Daqi: Massaging the area where armpit hair grows can promote the secondary development of hair follicle cells and the secretion of male hormones.
