With panels that emit 650 nanometers of red light—a wavelength shown in research to support circulation, healthy hair follicles, and scalp rejuvenation—this ingenious cap is designed to stimulate hair growth. Wear it for 10 minutes every day to see results; consistency is key but easy to accomplish. The hat is both cordless and strangely cute—its marriage of tech and athleisure is seriously impressive.
