Why hair falls out a few weeks after being ill and how you can support it.
Hair loss after illness or COVID is a temporary reaction, in which stress on the body and a high fever push more hairs into the shedding phase. It usually appears 2 to 3 months after the illness and fades within a few months. Gentle scalp care supports the hair during this period.
Why hair falls out after illness
When the body goes through an illness with a high fever, it redirects its resources towards recovery. As a result, many hair follicles enter the resting phase at the same time, and after a few weeks these hairs begin to fall out. This is how hair loss after illness occurs.
This is a temporary stress reaction of the body, not a lasting hair problem.

Telogen effluvium: hair loss after fever and stress
The phenomenon in which a large number of hairs enter the shedding phase at the same time after significant stress on the body is known as telogen effluvium. It can occur after a high fever, an infection, surgery, or intense emotional strain.
It is characteristic that the hair falls more evenly across the whole head, rather than in patches, and that the process is reversible over time.
Hair loss after COVID: what to expect
Hair loss after COVID follows the same mechanism: the illness and the high fever are a stress on the body, which temporarily shifts the hair cycle. Many people notice a more noticeable hair loss a few weeks to months after having the infection.
The good news is that in most cases this is a temporary state, and the hair gradually regains its density.
How long hair loss after illness lasts
Usually hair loss after illness appears 2 to 3 months after the acute period and lasts a few months. For most people, hair density recovers within six months to a year.
