Treatment

Treatment of hirsutism with no sign of endocrine disorder is not necessary. For women who do need or seek treatment, it may involve treating any underlying disorder, developing a self-care routine for unwanted hair, and trying various therapies and medications.

Medications

If cosmetic or self-care methods of hair removal haven't worked for you, talk with your doctor about drugs that treat hirsutism. With these medications it usually takes up to six months, the average life cycle of a hair follicle, before you see a significant difference in hair growth. Options include:

• Oral contraceptives. Birth control pills or other hormonal contraceptives, which contain estrogen and progestin, treat hirsutism caused by androgen production. Oral contraceptives are a common treatment for hirsutism in women who don't want to become pregnant. Possible side effects include nausea and headache.

• Anti-androgens. These types of drugs block androgens from attaching to their receptors in your body. They're sometimes prescribed after six months on oral contraceptives if the oral contraceptives aren't effective enough.

  The most commonly used anti-androgen for treating hirsutism is spironolactone (Aldactone, CaroSpir). The results are modest and take at least six months to be noticeable. Possible side effects include menstrual irregularity. Because these drugs can cause birth defects, it's important to use contraception while taking them.

• Topical cream. Eflornithine (Vaniqa) is a prescription cream specifically for excessive facial hair in women. It's applied directly to the affected area of your face twice a day. It helps slow new hair growth but doesn't get rid of existing hair. It can be used with laser therapy to enhance the response.

Procedures

Hair removal methods whose results may last longer than self-care methods — and which may be combined with medical therapy — include:

• Laser therapy. A beam of highly concentrated light (laser) is passed over your skin to damage hair follicles and prevent hair from growing (photoepilation). You might need multiple treatments. For people whose unwanted hair is black, brown or auburn, photoepilation is usually a better option than electrolysis.

  Talk with your doctor about the risks and benefits of the various lasers used for this hair removal method. People with tanned or darkly pigmented skin are at increased risk of side effects from certain lasers, including a darkening or lightening of their usual skin tones, blistering, and inflammation.

• Electrolysis. This treatment involves inserting a tiny needle into each hair follicle. The needle emits a pulse of electric current to damage and eventually destroy the follicle. You might need multiple treatments. For people with naturally blond or white hair, electrolysis is a better option than laser therapy.

  Electrolysis is effective but can be painful. A numbing cream spread on your skin before treatment might reduce discomfort.
