Theradome’s 680 nm medical grade lasers penetrate deep into the hair follicles in order to regrow and strengthen your hair. Red light therapy (LEDs) are 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. Electronic equipment use LED lights as ON and OFF indicators. 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.
Many laser devices unfortunately add LEDs mixed with medical grade lasers to be able to claim more overall lights, however, the quality of lasers are more important than the quantity of them.
