Previously only available to women, the LH80 PRO Laser Helmet uses laser phototherapy to stimulate weak hair follicles and provide them with targeted laser energy. The laser energy improves the cellular metabolism and protein synthesis required to grow and maintain a healthy head of hair. Therapy protocol with the LH80 PRO is two 20-minute treatments each week. It uses 80 red lasers to generate over 440 J of energy and treat the full scalp area. The lasers deliver the optimum wavelength of light for hair growth — 678 nm. Theradome is a medical therapy company located in Silicon Valley focused on developing advanced laser phototherapy devices and complementary scalp products.
