Informed consent was obtained from all participants registered with the UK Biobank. 3 Options included the following text: pattern 1 "no hair loss," pattern 2 "slight hair loss," pattern 3 "moderate hair loss," pattern 4 "severe hair loss." 4 COVID-19 testing was carried out on symptomatic patients per National Health Service guidelines 5 .

Descriptive frequencies for COVID-19 results, balding patterns, age, and BMI are reported in Our study compared a large sample of hospitalized COVID-19 positive patients to a control group of hospitalized COVID-19 negative patients and thus builds upon and supports the observations of Wambier 1 and coauthors. A notable limitation of our work is that balding data was self-reported. While the exact mechanism remains unknown, severe androgenic alopecia seems to be associated with hospitalization for COVID-19. The large effect of baldness on the risk of COVID-19 suggests that the presence of severe baldness may help clinicians and public health authorities identify and protect those at greatest risk.
