Chemotherapy-Related Hair Loss (Alopecia) in Children
What is chemotherapy-related hair loss in children?
Hair loss is a common side effect of chemotherapy. It can affect the hair on the head,
and also the eyebrows, eyelashes, and facial and pubic hair. Not all chemotherapy
causes hair loss. And not all children lose hair in the same way. A child may lose
his or her hair with a medicine and another child taking the same medicine may not.
