(Excess Male-Pattern Hair Growth)


Hirsutism is excess male-pattern hair growth in women. The coarse, dark hair can grow in areas such as the face, chest, and back.


Hirsutism is often due to an increased level of a male sex hormone called androgen. Some common causes are:

Sometimes the cause is not known.

Risk Factors

This problem is more common in women of reproductive age.


The most common problem is excess hair growth on the face, arms, back, armpits, groin, or chest. Severe problems may be:

  • A deep voice
  • Male-pattern baldness
  • Acne
  • Decreased breast size
  • Increased muscle mass
  • Increased size of clitoris
  • Abnormal or absent menstrual periods


The doctor will ask about symptoms and past health. A physical exam will be done. It will focus on areas of hair growth. This is often enough to make the diagnosis.

Blood tests may be done to check hormone levels.

Other tests may be done to look for a cause.


Any underlying causes will need to be treated. This may stop hair growth in some women.

The hair does not need to be removed, but some women may choose to do so. Options are:

  • Hair removal with:
    • Shaving
    • Bleaching
    • Chemical treatment (depilatories)
    • Waxing
    • Electrolysis
    • Laser treatment
    • Intense pulsed light (IPL)

Medicine may be given to lower the level of male hormones. Some examples are:

  • Oral contraceptives
  • Spironolactone
  • Finasteride
  • Flutamide
  • Metformin

Eflornithine may also be given. It blocks a substance needed for hair growth.


There are no current guidelines to prevent this health problem.
