Beard growth in women may be a normal phenomenon, usually caused by genetic factors; it may also be an abnormal phenomenon, which may be related to premature ovarian failure, adrenal tumors, polycystic ovary syndrome or other factors. 1. Normal phenomenon: it may be caused by genetic factors, parents have vigorous body hair, affected by genes, women are more likely to show vigorous body hair, which may lead to beard growth. 2. Premature ovarian failure: some women suffer from premature ovarian failure, which reduces the function of the ovaries, the body does not have enough estrogen secretion, but the level of androgen is relatively high, a common manifestation of this is that they are prone to grow a beard. 3. Adrenal tumors: when a woman grows a beard, it is possible that androgenic adrenal tumors are developing. Adrenal cortex can secrete androgens, if there are androgenic adrenal tumors, these tumors will also lead to a relative increase in the secretion of androgens, and the phenomenon of women’s beard growth will be more obvious. 4. Polycystic Ovary Syndrome: Polycystic Ovary Syndrome (PCOS) causes high levels of androgens and low levels of estrogen, leading to beard growth in women. 5. Other factors: such as long-term use of glucocorticoid drugs, as well as immunosuppressive drugs, such as cyclosporine drugs, etc., may cause an abnormal increase in hair or aggravation of all parts of the body, including the beard. Therefore, if the situation of female beard growth, it is recommended to go to the hospital in time for examination and treatment under the guidance of the doctor.
