It’s important to note that there was no control group in the study.
A July 2020 study compared balding patterns in 336 men hospitalised for COVID-19 and 1,605 men hospitalised without COVID-19.
It found that men with the most pronounced pattern of baldness were more likely to test positive for COVID-19.
What’s more, a November 2020 population study surveyed 43,565 people on topics like amount of hair loss, underlying health conditions, and COVID-19 status or outcome.
