Background: Central centrifugal cicatricial alopecia (CCCA) is a type of scarring alopecia exclusively seen in women of African descent. The etiology is unknown and epidemiologic studies including data on comorbidities in patients with CCCA are limited. Our primary objective was to identify possible etiologic and lifestyle associations in patients with CCCA. Materials and Methods: A retrospective chart review was conducted for patients diagnosed with CCCA between January 1, 2013, and January 1, 2018, at a university dermatology outpatient clinic. Controls consisted of age-, sex-, and race-matched African–American women diagnosed with other hair loss conditions. Data from 74 cases and 96 controls were collected and analyzed via logistic regression. In addition, a phone survey was conducted in the CCCA cohort asking specific questions related to their condition and quality of life. Results: A significant relationship was found between CCCA and previous pregnancies as well as the use of chemical relaxers: patients with CCCA were 11.71 times more likely to have had a previous pregnancy (P < 0.001) and 12.37 times more likely to have used chemical relaxers in the past (P < 0.001). Association with uterine fibroids was found not statistically significant (P > 0.05). Conclusion: We identified an association between previous pregnancies and use of chemical relaxers in patients diagnosed with CCCA when compared to controls. These findings may help to plan prospective studies aiming at establishing a more concrete link between hormones and CCCA.
