Anagen Effluvium (Chemo-Therapy Drugs)

Anagen Effluvium

Anagen effluvium is hair loss that occurs during the anagen phase of the hair cycle, when the hairs are actively growing. It prevents the matrix cells, which produce new hairs, from dividing normally. This type of hair loss usually occurs within a few days to weeks after taking the medication.

It’s most common in people who are taking chemotherapy drugs and is often severe, causing people to lose most or all of the hair on their head, as well as their eyebrows, eyelashes, and other body hairs. After the treatment ends, the hair typically begins to regrow.
