This is the cooling cap that helps relieve common side effects of chemotherapy such as hair loss, neuropathy pain, and inflammation. The cap is lined with individual gel ice cubes that are surrounded by a fluid-like gel and activated by cooling in the refrigerator or freezer. This unique cooling system cools the scalp and constricts the blood vessels, which allows less of the chemotherapy drug to reach the hair follicles. With a ponytail friendly design, hook-and-loop fasteners for a custom fit, and a soft inner lining that’s gentle against sensitive skin. For cold use only; not for use with pacemaker or insulin pump. One size fits most. Blue.
