Which of the following can cause hirsutism?

• A. Genetics
• B. All of the above
• C. Constant rubbing of the skin
• D. Drugs for seizures

Answer: (B)

Hirsutism can arise from a variety of influences, not just one simple trigger. Genetics can set a person up with a pattern of hair growth and a tendency for follicles to respond to androgens more strongly. Friction or constant rubbing of the skin can stimulate hair growth in the treated area through local effects on the hair follicles. Some medications, including drugs used to treat seizures, are known to cause increased hair growth as a side effect. Because each of these factors can contribute to hirsutism, “All of the above” is the best choice.
