What about girls with beards? hungry
First of all, you should find out why women don't have beards.

Both animal and human hair can protect the body and attract the opposite sex. In terms of protection, it can keep warm and block the sun. Special hair can also defend against enemies, for example, mane can protect the neck of animals. When attracting the opposite sex, male peacocks show off their beautiful feathers with screens to attract female peacocks. Human hair also has the function of attracting the opposite sex.

Judging from the changes of human growth hair, when a baby is born, there is a layer of fluff on his body. After a while, the fluff falls off and is replaced by soft wool. In adolescence, soft hair will become the first mature hair. Hair development is controlled by gonads. Androgen can promote the full growth of beard and body hair, but inhibit hair growth; Female hormones can promote hair growth, but inhibit beard growth. That's why girls don't have beards.

To sum up, women's long beard is caused by insufficient secretion of female hormones. It is recommended to go to the hospital to see estrogen.

Sometimes we can see that some women have beards on their upper lips, cheeks and jaws, even as thick as men, which affects their beauty and brings great mental burden and pain to these lesbians. What's going on here? To understand this problem, we must first understand the growth regulation mechanism of hair.

Hair growth is controlled and regulated by nervous and endocrine systems, among which endocrine androgen metabolism has the most obvious influence. Androgen can stimulate the growth of hair mother cells. Testosterone can promote the growth of trunk, limbs, beard, armpit and pubic hair. Therefore, local injection of testosterone can regenerate people with axillary hair or pubic hair loss. Therefore, when androgen metabolism is abnormal and hair growth is abnormal, women can see beards. Most women can see different degrees of facial hirsutism during pregnancy, which usually disappears 6 months after delivery. This is also because of the change of androgen during pregnancy, which is a physiological change. Some beards of women after menopause also belong to physiological changes.

Female beards are mainly seen in some syndromes. The most common female beards are diabetes syndrome and bilateral polycystic ovary syndrome. Female beard diabetes syndrome is seen in menopausal women. Its main clinical manifestations are female beard, hairy body and obvious obesity, often accompanied by diabetes and hypertension, but there are no other male characteristics except hairy body. This disease is mainly due to the increase of androgen level caused by pituitary adenoma or adrenal cortical tumor.
