Excessive or unwanted hair in women Health Article

Definition

The normal amount of body hair varies widely among women. Usually, a woman will only grow fine hair (peach fuzz) on her lips, chin, chest, abdomen, or back. When women grow coarse, dark hairs in these areas, the condition is called hirsutism. This pattern of hair growth is more typical of men.

Alternative Names

Hypertrichosis; Hirsutism; Hair - excessive (women); Excessive hair in women; Hair - women - excessive or unwanted

Common Causes

All women normally produce low levels of male hormones (androgens). Unwanted hair growth (hirsutism) in women may occur when the body makes too much male hormone.

In most cases, the exact cause is never identified. It tends to run in families. In general, hirsutism is a harmless condition. But many women find it bothersome, or even embarrassing.

A common cause is polycystic ovarian syndrome (PCOS). Women with PCOS and other hormone conditions that cause unwanted hair growth may also have acne, problems with menstrual periods, trouble losing weight, a deeper voice similar to that of men, and diabetes. If these symptoms start suddenly, there may be a tumor that releases male hormones.

The following other causes of unwanted hair growth are rare:

• Tumor or cancer of the adrenal gland
• Tumor or cancer of the ovary
• Cushing's syndrome
• Congenital adrenal hyperplasia
• Hyperthecosis (a condition in which the ovaries produce too much male hormones)
• Medications (testosterone, danazol, anabolic steroids, glucocorticoids, cyclosporine, minoxidil, phenytoin)

Rarely a woman with hirsutism will have normal levels of male hormones, and the specific cause of the unwanted hair growth cannot be identified.

Home Care

Hirsutism is generally a long-term problem. There are a number of ways to remove or treat unwanted hair. Some treatment effects last longer than others.

Weight loss in overweight women can reduce hair growth. Bleaching or lightening hair may make it less noticeable.

Temporary hair removal options include:

• Shaving does not cause more hair to grow, but the hair may look thicker.
• Plucking and waxing are fairly safe and are not expensive. However, they can be painful and there is a risk for scarring, swelling, and skin darkening.
• Chemicals may be used, but most have a bad odor.

Laser hair removal (electrolysis) uses electrical current to permanently damage individual hair follicles so they do not grow back. This method is expensive and multiple treatments are needed. Swelling, scarring, and redness of the skin may occur.
