COVID 19, androgens, and androgenic alopecia
The severity of severe acute respiratory syndrome coronavirus 2 (SARS CoV 2) in males may be due to the higher androgen expression. It is also known that androgen sensitivity is correlated with androgenic alopecia. The "Gabrin sign" identifies those with severe androgen alopecia (Hamilton Norwood scale 3 7) who are at a higher risk for developing severe coronavirus disease 2019 (COVID 19) symptoms. The aim of this review article is to examine the current scientific evidence of the link between androgenic alopecia, androgens, and the severity of COVID 19 and also, to review possible therapeutic targets to impact COVID 19 outcomes.
