The side effects of chemotherapy (chemo) depend on the type of chemo and the amount given. Being ready for and managing side effects can help you cope with them.
Many chemo medicines kill fast-growing cells. This means that they affect healthy cells that grow fast, as well as cancer cells. Because cells in hair follicles are fast growing, many chemo medicines cause hair loss, or alopecia. People can lose hair anywhere on the body—the head, eyebrows, eyelashes, and facial and pubic hair. Loss usually occurs 2 to 3 weeks into treatment, depending on the medicines used. Once it starts to fall out, hair may just get thinner, or it may fall out altogether.
Just as each person is different, so is their reaction to treatment. Side effects may be severe or mild. Or you might not have any. Talk with your cancer care team about the possible side effects of your treatment before treatment starts.
People often choose to wear wigs, scarves, or hats while or after losing their hair. If this is what you'd like to do, pick them out ahead of time and start wearing them before your hair is completely gone. Other ways to manage your hair during treatment include:
Wash it less often.
Use a gentle moisturizing shampoo.
Don't use coloring products, perms, or other products with strong chemicals.
Don't use brush rollers, curling irons, or blow dryers on hot settings.
Consider cutting your hair short before you start treatment.
You might want to talk with your treatment team about using a cold cap during your chemo infusions. These devices can be rented or bought online. The cold makes the blood vessels in your scalp tighten up. As a result,less blood carrying the chemo medicine goes through the vessels. That might help prevent damage to your hair follicles and reduce hair loss.
Yes, in almost all cases hair grows back. The color or texture may be different at first. But it usually starts to grow about 6 weeks after you've completed chemo. As your hair grows back, try to limit shampoos to twice a week. Also don't use chemical products like perms or straighteners until the hair has regrown. Permanent or semipermanent hair coloring should not be used for at least 3 months after treatment ends.
