Laser treatment for hair loss came onto the market a few years ago and it is a therapy that is promising, but expensive. The lasers used in hair loss therapy are cool lasers, meaning they do not burn the skin the way certain wavelength lasers do that tackle other problems, like aging facial skin.

A researcher showed that shaved mice exposed to cool laser light regrew their hair twice as fast as shaved mice in normal light.
