How does photobiomodulation work?
Photobiomodulation consists in applying low level laser light to the scalp for 20 minutes, at least 4 times a week, in order to stimulate follicular unit cells and blood microcirculation that nourishes them. As a consequence of circulation activation, more nutrients and oxygen reach hair follicles. So the main benefit of low level laser is hair rejuvenation and scalp nutrition.
