Why do some people have no armpit hair?

One of the reasons why women don't have armpit hair is the low level of androgen in their bodies. The second reason is that the receptors that accept androgens in axillary hair follicles are insensitive to androgens or have other defects, and some of them have no such receptors at all. Men without armpit hair are likely to have hypoplasia.

The endocrine, menstrual cycle, sexual development, sexual function and fertility of most women with alopecia are normal, so alopecia is physiological and will not affect their health.

Extended data:

The function of armpit hair is to increase friction and help sweat. However, armpit hair does not detoxify at the same time, and the decomposition of human toxins is mainly completed in the liver and excreted with urine and intestines.

For people who shave armpit hair by physical means, if the skin is damaged due to improper shaving, it is really easy to cause infection and pore blockage, which may have a certain impact on perspiration. Therefore, it is best to use clean and sharp shaving tools, fully moisten them before shaving, and properly use lubricating products. At the same time, remember not to use shaving tools with others.
