Central centrifugal cicatricial alopecia
Its cause is likely multifactorial. The hair-grooming factors that are often attributed to CCCA are cornrow and braiding with and without extensions and weaves with sewn-in or glued-on hair, use of hot combs, and frequent use of hair relaxers. However, there are conflicting reports on the potential associations.
Clinical features include a round alopecic patch of the vertex, with symmetrical centrifugal expansion, demonstrating early disease at the periphery, where scarring may be subtle. It is slowly progressive, culminating in shiny, flesh-colored scarring alopecia. Some residual hairs may be found throughout the involved area.
CCCA was formerly referred to as hot comb alopecia and may also be known as follicular degeneration syndrome, pseudopelade in African Americans, and scarring alopecia in African Americans.
