Excessive or unwanted hair that grows on a woman’s body and face is the result of a condition called hirsutism. All women have facial and body hair, but the hair is usually very fine and light in colour.
The main difference between typical hair on a woman’s body and face and hair caused by hirsutism is the texture. Excessive or unwanted hair that grows on the face, arms, back, or chest is usually coarse and dark.
Hirsutism is not the same as hypertrichosis, which refers to excess hair in areas that aren’t dependent on androgens (male hormones). Hirsutism is excess hair in areas where it’s typically seen in men, such as the face and lower abdomen. Hypertrichosis, on the other hand, can increase hair anywhere on the body.
According to the Indian Journal of Dermatology, hirsutism affects between 5 and 10 percent of women. It tends to run in families, so you may be more likely to have unwanted hair growth if your mother, sister, or other female relative also has it.
