An impressive case of alopecia universalis after COVID-19 vaccination: a coincidental finding or a consequence?

BACKGROUND: Several cutaneous manifestations in patients undergoing COVID-19 vaccination have been described in literature. CASE REPORT: Herein, we present a case of alopecia universalis that occurred after the first and second dose of Comirnaty vaccine. A bibliographic search was conducted and a total of 14 studies concerning the association were reviewed. CONCLUSIONS: Given the autoimmune pathogenesis of the disease, we discussed the potential role of SARS-CoV-2 infection and vaccination as a trigger for the development of hair loss. Physicians should be aware of SARS-CoV-2 vaccine-related hair loss and properly treat this undesirable effect.
