Partial or complete loss of hair or alopecia may result from genetic factors, aging, or local or systemic disease. (Seborrheic dermatitis and psoriasis, the dermatoses that most commonly affect the scalp, very rarely produce alopecia.)Therapeutic options for alopecia are limited and include,topical minoxidil, oral finasteride 1 mg/day, and surgical intervention (hair transplantation). These treatments may be used alone or in combination.
