Central centrifugal cicatricial alopecia (CCCA) is the most common type of primary scarring alopecia affecting women of African ancestry, with an estimated prevalence of 2.7 to 5.6%. It may be triggered by hair-grooming habits; however, familial occurrence has been reported. Mean age at presentation is 36 years. The first sign is often unexplained hair breakage, followed by hair thinning, primarily involving the vertex scalp and progressing centrifugally. Histopathologic examination shows varying degrees of lymphocytic inflammation, follicular degeneration, and fibrosis (Malki et al., 2019). [from OMIM]
