"Chemotherapy hair cut" refers to a type of haircut that is typically given to people who are undergoing chemotherapy. Chemotherapy is a treatment for cancer that can cause hair loss, so a chemotherapy hair cut is designed to help people manage this side effect.
Losing hair can be a traumatic experience for people, so a chemotherapy hair cut can provide a sense of control and comfort. It can also help people to feel more confident and positive about their appearance during a difficult time.
