Abstract

|
Androgenetic alopecia (AGA) is a common form of hair loss that usually occurs in the third or fourth decades of life in men, with later onset in women. AGA does rarely occur, however, in the pediatric population. Adolescent AGA is pattern hair loss occurring in boys and girls between 12 and 18 years of age. We herein report the case of a 16-year-old girl with a 5-year history of diffuse hair loss on the crown. Her father had a history of AGA, and the hair pull test was negative. Sex hormone levels and thyroid function test were within the normal range. Phototrichogram analysis revealed diffuse hair thinning over the frontal and vertex areas, and the percentage of vellus hair was higher on the vertex than the occiput. We diagnosed the patient with adolescent AGA. She was prescribed 3% topical minoxidil, and improvement was visible on the clinical photograph and phototrichogram after 2 years of treatment.
