Alopecia areata and subsequent Marie Antoinette syndrome following COVID-19 infection and vaccination: A case report.

Numerous cutaneous manifestations related to the COVID-19 (severe acute respiratory syndrome coronavirus 2) viral infection have been reported in literature. In this case report, we describe two acute hair-associated manifestations-the first being alopecia areata and the second is a case of Marie Antoinette syndrome or Canities subita where all the scalp hair has become white almost overnight. Both entities of hair changes were seen in the same patient.
