Cooling caps in wider spread use for those undergoing chemotherapy.
More cancer patients may be able to ward off hair loss during chemotherapy treatment.
A cooling cap approved in 2015 for use in breast cancer patients has won expanded approval from the U.S. Food and Drug Administration.
The DigniCap Cooling System can now be used for patients with solid tumors, the FDA announced.
The computer-controlled cap contains liquid that circulates and cools the scalp, narrowing blood vessels. This reduces how much of the chemotherapy drugs reach hair follicle cells, the FDA said.
Cooling also decreases activity of hair follicles and slows cell division. The result: Chemo drugs don’t affect them as much, according to the FDA.
Hair loss is a common side effect of chemotherapy, especially during treatment of most solid tumor cancers. Hair may fall out all at once, little by little or become thin. It’s usually temporary — and upsetting.
