The growth of small beards in girls is usually mainly due to the overproduction of androgens in the body. It is usually seen in some adolescent children. After puberty, especially in girls, not only the secretion of estrogen is strong, but also the secretion of androgen is strong, so it may produce androgenic characteristics, such as beard. But this kind of beard generally after puberty, most of them can fade on their own, or gradually fall off, so generally do not need to carry out special treatment. However, some girls who have a beard that does not fade for a long time, even into youth, can undergo some treatment, usually electrolytic therapy.
