Does Covid-19 cause hair loss?
Temporary hair loss is normal after a fever or illness and fever is a common symptom of Covid-19. A few months after having a high fever or recovering from an illness, many people see noticeable hair loss. While many people think of this as hair loss, it’s actually hair shedding.
The medical name for this type of hair shedding is telogen effluvium. It happens when more hairs than normal enter the shedding (telogen) phase of the hair growth lifecycle at the same time. Fever or illness can force more hairs into the shedding phase.
Most people see noticeable hair shedding two to three months after having a fever or illness. Handfuls of hair can come out when you shower or brush your hair. This hair shedding can last for six to nine months before it stops. Most people then see their hair start to look normal again and stop shedding.
