What is 620 nm wavelength?
620 nm wavelength is a specific wavelength of light linked to DHT inhibition.
DHT is a hormone that can cause hair follicles to shrink and eventually lead to hair loss. The 620 nm light stimulated the release of nitric oxide, a molecule that plays a role in blood vessel dilation and hair growth.
