Hormone related hair loss (genetic hair loss in men and women) and other types of hair loss cause the hair follicle to produce thinner hair shafts. Why -- because of a hormone called DHT. DHT will attack the follicle by choking it out. As a result, the blood supply to the follicle is decreased – eventually causing the hair follicle to atrophy (unable to produce new growth).
During laser treatment, cells in the follicle absorb the low level light and become more active, this is known as photo-bio-stimulation. It’s like giving your cells vitamins for a healthy metabolism. By increasing the blood flow, cells then begin to repair themselves, jump-starting the growth process that leads to thicker, fuller, healthier hair.
