What is the reason for the growth of sweat hair at the corners of the eyes

The growth rate of sweat hair is directly related to the secretion of male hormones in the human body. Generally speaking, people who secrete more male hormones have more body hair growth. Moreover, sweat hair may grow in many parts of the human body, and sweat hair mainly grows in the hair follicles of the human body. Some people find that they have hair growing around the corners of their eyes. So, what is the reason for the growth of sweat hair at the corners of the eyes?

First, let's analyze the reasons for the formation of body hair. Each of us has body hair, some are light and some are heavy. Generally, girls have lighter hair and boys have heavier hair. The density and thickness of hair depends largely on the level of male hormones in the human body and the sensitivity of hair follicles to hormones.

In women, androgens are mainly secreted by the adrenal cortex and in small amounts by the ovaries. During puberty, girls gain body hair, and grow pubic hair and armpit hair, which is the effect of the male hormones secreted by the adrenal cortex and ovaries. It’s just that the testosterone level in women is much lower than that in men. Taking testosterone as an example, men have more than 10 times more than women.

Why do some girls have heavy sweat hair? This question can be roughly summarized as follows:

1. Differences within the normal range. Generally speaking, light hair and fair and delicate skin are one of the characteristics of women, but this is not entirely true. There is a great deal of variation in the distribution of hair among normal women. According to relevant records, some people abroad have made some statistics: among normal women aged 15 to 44, 30% have mustaches, 9% have obvious cheek hair, 6% have thick hair below the temples, and 30% and 70% have darker and thicker hair on their forearms and calves respectively.

2. Skin hair follicles are too sensitive to male hormones.

3. Related to genetics. If the parents have more body hair, their daughter is likely to have more body hair.

4. Certain diseases can cause morbid hirsutism.

5. Long-term and excessive use of hormones such as cortisone and testosterone can also cause hirsutism.
