Anabolic-androgenic steroids can cause male-pattern hair growth in females.

Medically defined as hirsutism, this condition is characterized by hair growth in androgen-sensitive areas of the body. With hirsutism, coarse black hair (terminal hair) may develop on the face, chest, abdomen, and back—areas typically associated with male hair growth rather than female. Treatment for hirsutism usually involves the immediate discontinuation of anabolic-androgenic steroids and the initiation of methods to minimize the androgenic effects on hair follicles. This may include the use of oral estrogens, anti-androgens (such as spironolactone), or finasteride. Topical ketoconazole, an antifungal agent, has also been used successfully. The response to treatment can be slow, and changes caused by anabolic-androgenic steroid use may persist for a year or more. Regular hair removal treatments may also be necessary for the affected areas.

The severity of hirsutism will depend on the persistence of the drug, the dosage used, the duration of use, and the individual's sensitivity.
