Chemotherapy and hair loss: What to expect during treatment

What should you expect?

Hair usually begins falling out two to four weeks after you start treatment.

It could fall out very quickly in clumps or gradually. You'll likely notice accumulations of loose hair on your pillow, in your hairbrush or comb, or in your sink or shower drain. Your scalp may feel tender.

Your hair loss will continue throughout your treatment and up to a few weeks afterward. Whether your hair thins or you become completely bald will depend on your treatment.

People with cancer report hair loss as a distressing side effect of treatment. Each time you catch a glimpse of yourself in a mirror, your changed appearance is a reminder of your illness and everything you've experienced since your diagnosis.
