It is true that hair loss caused by chemotherapy:

Question

Quizplus · Accepted Answer

Chemotherapy works by killing cells that divide rapidly, such as cancer cells. Unfortunately, some types of normal cells in the body also divide rapidly, such as the cells in the hair follicles. Therefore, people who are receiving chemotherapy often lose their hair. Cancer is not the cause of the hair loss. When the therapy is finished, the hair will usually grow back. The medication causes the hair loss and so it is not an indication of the treatment's success or failure.
