What Are the Causes of Female Facial Hair Growth?

Excessive hair growth, also known as hirsutism, is a common problem that women can experience at any time in life. Hirsutism consists of dark coarse hair growing on a woman’s face or body in similar placement to that of male hair growth. Hirsutism is the result of too many androgens (male hormones) being present in the female body, resulting in a hormonal imbalance. An estimated 1 in 20 women in the United States is affected by hirsutism, according to the American Academy of Dermatology.

Pregnancy

Pregnancy is one of the most common causes of female facial hair growth. As a fetus grows and matures in the body, a mother’s hormones begin to change in response to what is needed for development and growth to continue.

Androgen hormones are one type that can be affected during pregnancy. As androgens increase, secondary side effects of their presence such as dark hair growth on the upper lip and chin, can occur.

Medications

Certain hormone medications can also cause problems with female facial hair growth. For example, norgestrel, which is found in some oral contraceptives may increase androgen levels in the body, resulting in facial hair growth. Other medications that can cause this to occur include steroid medications, including the corticosteroid prednisone.

Genetics

Genetics can also play a role in facial hair growth. Your genes determine how sensitive your skin and hair follicles are to androgen hormones in your body. If past female family members have had problems with facial hair, there is an increased chance that you may as well have problems with facial hair.

Disease

Disease or disorders of the ovaries and adrenal glands can also cause abnormal facial hair growth. The most common of these is Polycystic ovarian syndrome (PCOS), according to the American Society for Reproductive Medicine.

During PCOS the ovaries produce excess amounts of androgens, resulting in facial and body hair growth. Other disorders and diseases that could cause facial hair growth include tumors of the ovaries or adrenal glands, Cushing’s disease and onset adrenal hyperplasia.

Menopause

Menopause may also increase androgen presence in the body resulting in facial hair growth. This occurs as estrogen production decreases, and testosterone production from the ovaries or adrenal glands increase. Hormone therapy can restore balances back to normal, but comes with varying side effects such as breast soreness and nausea.
