Treatments like chemotherapy, radiation therapy, and some hormone therapies and biological therapies may cause you to lose your hair. Your hair usually starts to come back four to six weeks after chemotherapy treatment stops and around three to six months after the end of radiation treatment.

Once your hair grows back, keep in mind that it may not be the exact same as it was before. Your hair may be a different texture or colour, or it may not be as strong as it was before. To make sure your hair is as strong as possible, it’s best to avoid hair colouring, perms or extreme heat. Try to wait until you’ve had three haircuts or trims before you start to chemically treat your hair again. To help add body to fine hair, you can also use a protein conditioner.
