Telogen Effluvium in Patients Recovering from COVID-19

The observational study conducted by the Icahn School of Medicine at Mount Sinai Hospital involved 10 patients who reported symptoms of Telogen Effluvium (TE), a type of hair loss, following COVID-19 symptoms. The study found that 9 out of 10 patients had mild COVID-19 symptoms with an average onset of hair shedding 73 days after infection. None of these patients had a previous history of hair loss. In comparison, a literature review identified 28 patients, 50% of whom were hospitalized for severe COVID-19 infection with an average onset of TE 87 days after infection, and 12% had pre-existing androgenic alopecia. The study concluded that TE can occur following both mild and severe COVID-19 infection, and dermatologists should expect an increase in TE in areas heavily affected by COVID-19.
