What is red light hair therapy?
Red light hair therapy refers to low-level laser and LED caps and combs marketed for hair regrowth, such as iRestore, Capillus and Kiierr, searched by people with thinning hair. The devices are FDA-cleared for some claims and expensive. It signals demand for at-home hair-loss devices and the telehealth and supplement products sold alongside.
