TLDR Some people lose a lot of hair after having COVID-19.
The review article by Szendzielorz and Bednarek discusses the observation of excessive hair loss as a complication after infection with the SARS-CoV-2 virus, which causes COVID-19. This hair loss is seen in both asymptomatic and symptomatic patients and is primarily telogen in nature. The issue affects both men and women, regardless of age and coexisting diseases. If left undiagnosed, this excessive hair loss can lead to hair thinning and even baldness.
