Materials and Methods: A case series study was done from October 1st2020 to March 31st2021 at Neumology consultation of a private medical center at Chiapas, Mexico, including patients that had recurrently reported hair loss of unexplained cause after the SARS-CoV-2 infection. Results: Information was collected from 28 patients, 16 men and 12 women, the hair loss began one month after the infection and in 5/28 it persisted for more than 6 months. Conclusions: Having a series of cases where all have in common having been infected by SARS-CoV-2, the association is impossible, so these alterations of the hair follicle can be caused by SARS-CoV-2 and should be included to the long list of symptoms that occur in this entity.
