COVID Related Shedding Occurs Earlier than Typical TE
Telogen effluvium occurs via a number of mechanisms but often occurs 2-3 months after a trigger. Common triggers of telogen effluvium include stess, low iron levels, thyroid problems, medications, weight loss and infection.
Studies have shown that COVID shedding can sometimes occur sooner than the typical 2-3 months. A new study from Thailand interviewed 43 patients with hair loss after COVID. Shedding occurred on average around 1 month after infection. Females had more severe shedding than males.
