There are physiological and pathological areola hair growths. Physiological hair growth in the areola is common in men and is caused by excessive secretion of androgens. The areola skin structure is different from the general skin, it is the junction of normal skin and nipple skin, this part of the growth of hair follicle cells. The developmental period of puberty may have different degrees of hair growth, some grow very fine down hair, some grow longer, thicker sweat hair. Physiological ones do not require treatment, pathological ones may be caused by overgrowth of hair follicles in the body if a few or two or a few are present. If the number is high, polycystic ovary syndrome should be ruled out, which is caused by excessive androgen production. If a woman has hairy areola, it is recommended to visit a hospital as soon as possible to clarify whether it is physiological or pathological.
