1. Causes of Chin Hair on Women:
The amount of hair on women’s chins varies and appears thicker or longer for a variety of reasons. When thick, coarse hairs appear on a woman’s chest, lips, back or chin, the condition is called hirsutism. The unwanted hair grows similarly to men’s beards on the chin. A number of reasons include Androgens, PCOS, Cushing Syndrome or Adrenal Hyperplasia.
