TLDR Many severe COVID-19 patients experienced temporary hair loss, but most regrew hair within six months.
This prospective cohort study assessed the prevalence of telogen effluvium (TE) in 77 patients hospitalized for severe COVID-19. Results showed that 68.8% of patients experienced TE, with 52.8% reporting early onset and 50.9% reporting moderate hair loss. Complete hair regrowth occurred in 20.7% of patients within three months and in 60.3% within six months, while 7.5% had chronic TE. Female sex, anemia, hypoproteinemia, and severe pneumonia were significantly associated with TE. The study highlights a high prevalence of COVID-19-associated TE, which generally has a good prognosis but can lead to chronic TE in a minority of cases.
