The FDA has cleared the DigniCap scalp cooling system for marketing, according to an announcement from the manufacturer. The cap aims to reduce chemotherapy-induced hair loss among women with breast cancer.

In a trial of over 100 women receiving chemotherapy (mostly taxanes) for stage 1 or 2 breast cancer, just 34% of patients who underwent scalp cooling lost over half of their hair, compared with 100% in the control group. There were no serious adverse events, although three patients discontinued use because of the cold sensation, which does not dip below 32 degrees F (0 degrees C).

During treatment, patients wear a tight-fitting silicone cap through which coolant circulates. When the scalp temperature is lowered, blood vessels constrict, which leads to less chemotherapy being delivered to the area. In addition, the intra-follicular metabolic rate is reduced, leading to less uptake of the chemotherapy drugs, according to the manufacturer.
