Facial hair growth in women may be a completely normal physiological second sign, or in some cases there is a genetic component. Most women have facial hair due to high levels of androgens, which stimulate hair growth in the body. The cause of high androgen levels may be related to genetic factors or may be due to polycystic ovary syndrome. The complex relationship between sex hormone levels and the genotype/expression of the race makes the areas where facial hair appears greater in women.
