Red light therapy hair growth is a non-invasive treatment approach that utilizes specific wavelengths of red or near-infrared light to stimulate hair follicles and promote hair regrowth.
Simply put, the red light penetrates the scalp and is absorbed by the cells of the hair follicles. This absorption of light energy then stimulates cellular activity and promotes several beneficial effects that contribute to hair growth.
By dilating blood vessels and increasing microcirculation, red light improves nutrient and oxygen delivery to the hair follicles, supporting their growth and strengthening the existing hair.
