Some people may have hair loss during their Afinitor treatment. But in studies, hair loss was only reported in people taking Afinitor along with exemestane (Aromasin) to treat breast cancer. Hair loss was not reported in people taking Afinitor to treat other conditions.If you experience hair loss from Afinitor that bothers you, talk with your doctor. They may be able to help determine the cause of your hair loss. In some cases, they may recommend treatment options, such as minoxidil (Rogaine) to help prevent hair loss from getting worse.
