Alopecia: diagnosis and management.

Abstract

Hair loss is a common problem that may affect both males and females in all age groups. Although androgenetic alopecia (common baldness) is the most frequently occurring type of hair loss, hair loss can result from a variety of local and systemic conditions. A detailed history, complete physical examination and directed use of laboratory tests are indicated in making the diagnosis. Specialized tests such as "hair pluck" and scalp biopsy may also be required. Treatment is focused on removing the cause of secondary hair loss, patient education and specific interventions for individual types of alopecia. All treatment strategies should address the significant cosmetic and psychologic impact of hair loss.
