We report an unusual case of verrucal alopecia occurring on the vertex scalp of a black woman, which was presumed to be secondary to use of a thioglycolate permanent wave preparation. We describe the clinical and histologic features of this chemical and traumatic alopecia as well as that of frontotemporal chronic traction alopecia resulting from use of sponge rollers. Common hair care practices are a frequent cause of alopecia in black women. Familiarity with these hair practices will aid in the accurate diagnosis, prevention, and proper management of this problem. The evaluation, causes, and differential diagnosis of alopecia in a black woman are discussed.
