TLDR COVID-19 can cause different types of hair loss, with telogen effluvium being the most common.
The study investigated hair loss in 25 patients following COVID-19 infection, identifying various types of alopecia, with telogen effluvium (TE) being the most common. Five patients experienced acute TE, with hair loss starting a median of 2 months post-infection and lasting a median of 4 months. Fifteen patients had chronic TE, beginning a median of 6 months post-infection and lasting a median of 9 months. Additionally, five patients developed patchy alopecia areata (AA) 2-3 weeks after infection, with hair loss lasting a median of 10 months. The study highlighted that post-COVID hair loss could manifest in different alopecia types, with TE being the most prevalent.
