Disorders of the hair and scalp in blacks.

The hair follicle and shaft in blacks have unique configurations. The occurrence of certain disorders such as hot-comb and traction alopecia, proximal trichorrhexis nodosa, trichonodoses, and pseudofolliculitis predominantly among blacks is related to the morphology as well as methods of caring for black hair. In addition, there are several disorders of unknown etiology such as dissecting cellulitis that also occur primarily in blacks. Familiarity with all of the structural differences that distinguish black hair and the disorders that affect the black patient's hair and scalp will enable dermatologists to provide proper diagnoses, treatment, and counselling for their black patients.
