Cicatricial alopecias tend to cause permanent hair loss. These disorders destroy hair follicles without regrowth and follow an irreversible course.21 It is likely that they involve stem-cell failure at the base of the follicles, which inhibits follicular recovery from the telogen phase.21 Inflammatory processes, including repetitive trauma as in trichotillomania, also may lead to stem-cell failure. Other processes may be caused by autoimmune, neoplastic, developmental, and hereditary disorders. Among these are discoid lupus, pseudopelade in whites, and follicular degeneration syndrome in blacks. Dissecting cellulitis, lichen planopilaris, and folliculitis decalvans also may cause scarring alopecia. Some disorders respond to treatment with intralesional steroids or antimalarial agents.21 Patients with these conditions should be referred to a physician who specializes in hair loss disorders.
