To strengthen and accelerate the growth of new hair and prevent existing hair from falling out, LED light therapy can be used to treat almost all types of hair loss problems. The LED light that shines on the hair and scalp consists of red light and yellow light. The red light (wavelength 660 nm) improves blood circulation under the skin in that area and stimulates metabolic processes, while the yellow light (wavelength 830 nm) stimulates collagen production, tightens the skin, and strengthens the nervous system in scalp cells. Each session takes approximately 20 minutes, but continuous treatments are necessary to see clearer and faster results.
