Racial Disparities in Hair Loss Episodes in Patients With Alopecia Areata: A Retrospective Cohort Study

This retrospective cohort study examined racial disparities in hair loss episodes among 482 patients with alopecia areata at Brown Dermatology from 2016 to 2020. It found that African American adults had a significantly higher incidence rate of hair loss episodes compared to White patients, with an incidence rate ratio of 2.23. In pediatric patients, those of other races, including Asians, also experienced higher rates of hair loss episodes than their White counterparts. The study underscores the need for further research into the mechanisms behind these racial and ethnic disparities in alopecia areata disease activity and highlights the importance of considering racial and age-related factors in managing the condition.
