Drug-Induced Hair Loss
How Is Drug-Induced Hair Loss Treated? continued...
One technique may help prevent hair loss during chemotherapy. It's called scalp hypothermia, and it involves placing ice packs on the scalp a few minutes before -- and for about a half-hour after -- chemotherapy treatment. Cooling the scalp reduces blood flow to the hair follicles, making it harder for the chemotherapy drugs to get into the follicular cells. Cooling also reduces biochemical activity, making the hair follicles less susceptible to damage from chemotherapy drugs. One concern with this technique is the risk of cancer recurrence in the scalp.
After chemotherapy treatment, the hair usually grows back in very quickly, but it may change in texture. In rare cases, the hair will stay thin even after treatment has been stopped. Minoxidil can help regrow hair that is slow to return. Some chemotherapy patients wear a wig or hat to hide their hair loss until their hair grows back.
