Androgenetic Alopecia in COVID-19: Comparison to Age-Matched Epidemiologic Studies and Hospital Outcomes With or Without the Gabrin Sign

This document discusses the correlation between androgenetic alopecia (AGA) and COVID-19 outcomes. Several studies have found that AGA is more prevalent in COVID-19 patients than in the general population, and that the presence of the Gabrin sign (a skin manifestation of COVID-19) is associated with a higher prevalence of AGA. The severity of AGA, as measured by the Hamilton-Norwood scale, is also associated with worse outcomes in hospitalized men. The document suggests that AGA may be a risk factor for severe COVID-19 outcomes in men, and encourages further research on the topic.
