When a chin hair is a health flag
There are times when chin hair is a red flag that something may be going on with your health. Excessive chin or facial hair, or suddenly increased growth in hair on any part of the face, may be a sign of a condition called hypertrichosis. The type of hypertrichosis specific to women is called hirsutism.
According to the Cleveland Clinic, hirsutism is common and affects 5 to 10 percent of women of childbearing age. It can cause dark, coarse hair growth on the chin, upper lip, chest, abdomen, and back.
Though the exact cause of hirsutism is not always known, it can also be caused by several medical conditions.
