Theradome’s 680nm medical grade lasers penetrate deep into the hair follicles in order to regrow and strengthen your hair. Red light therapy (LEDs) are too weak and don’t properly penetrate into the hair follicles.
LEDs are not lasers. Lasers are monochromatic which means they have a single color wavelength. LEDs are inexpensive and easy to make and can be often be seen in electronic equipment as an ON and OFF indicator. Lasers meet scientific standards and achieve results that LEDs could never achieve LED light spreads out and doesn’t have the narrow focus and follicle penetration that lasers do.
