What is unwanted hair in women?

Hirsutism (say "HER-suh-tiz-um") is extra hair on a woman's face or body. This hair is dark and coarse. It grows in a male pattern: on the face, like a man's facial hair, or on the body, especially the chest and back.

What causes it?

Usually extra hair growth (hirsutism) is not a medical problem. It can run in families or be a part of a woman's ancestry. In some women, hirsutism may be the result of higher-than-normal levels of certain hormones called androgens. These hormones are found in everyone, although men have a lot more of them. In women, androgens are produced by the ovaries or the adrenal glands.

Women with polycystic ovary syndrome (PCOS) often have hirsutism, along with acne and irregular menstrual cycles.

But some women with hirsutism don't have PCOS or any other cause that can be identified. Their hormone levels are normal, and so are their menstrual cycles. These women had a gradual increase in coarse hair growth. It may be that they inherited hair follicles that are more sensitive to androgens.

Hirsutism may also occur in some people who have diabetes or are living with obesity. In rare cases, the ovaries or adrenal glands may have a problem that can cause this hair growth.

How is it treated?

Your doctor may want to do blood tests or other tests to find out if a medical problem is causing your extra hair growth (hirsutism). If the cause is not a medical problem, treating it is often a matter of choice. That's because hirsutism usually isn't a sign of a health problem. Treatments include:

• Birth control pills. This is the most common treatment. Birth control pills contain hormones, so they help balance your body's hormone level.
• Antiandrogens. These are prescription medicines that lower the amount of male sex hormones in your body.
• Topical cream. Your doctor may prescribe a cream that you rub into affected areas to slow hair growth.
• Electrolysis. This method uses a very thin probe in the hair follicle. An electric current through the probe destroys the ability of that follicle to grow hair.
• Laser hair removal. This is a medical procedure that uses light treatments to heat and destroy hair follicles.

Women who have polycystic ovary syndrome (PCOS) and who are overweight may be able to reduce unwanted hair growth by reaching a weight that's healthy for them.

Some women prefer to use various home treatments for unwanted hair. These include shaving, waxing, and other methods to remove the hair.
