Androgens have the effect of stimulating the growth of hair mother cells. For boys, because There are more androgens secreted in the body, so boys will grow beards. Compared with boys, girls will not grow beards because of the higher content of estrogen and less androgen content in their bodies.

It makes girls appear male second sex and grow beard. For this situation, women can supplement natural estrogen, such as drinking soy milk. Soy milk is rich in soy isoflavones, which can regulate endocrine and promote hormone secretion. .
