The amount of hair on woman chin varies and appear thicker or longer for a variety of reasons, report the National Institutes of Health. When thick, coarse hair appears on a woman chest, lips, back or chin, the condition is called hirsutism. The unwanted hair grows similarly to men’s beards on the chin.
All women produce small amounts of the male hormones called androgens, hair begins to grow on the chin when a woman has an overabundance of the male hormones. The condition is not life-threatening or medically harmful. Most women with hormonal imbalances find the hair growth to be embarrassing, however, and seek ways to remove it.
Polycystic ovarian syndrome, or PCOS, is a common medical condition that causes an overabundance of chin hair. PCOS results from an imbalance of hormones and often causes additional symptoms as well as unwanted hair growth. Women with PCOS usually have trouble with their menstrual cycles, have a deeper voice and have difficulty losing weight.
The pituitary gland just produces too much ACTH hormones and causes the adrenal glands to excrete additional cortisol in the system. A tumour in the pituitary or adrenal gland also can cause the disorder.
Congenital adrenal hyperplasia can cause women to grow heavy coarse hair on their chins. In those born with the condition, the adrenal glands fail to produce enough cortisol, which causes strong male characteristics to from. Girls born with the birth defect also will have deep voices and early growth of pubic and underarm hair.
