DHT also known as Dihydrotestosterone is a biologically active metabolite of testosterone found in hair follicles. DHT is the cause of 95% of all hair loss. It reduces the hair follicle by shortening the growth (anagen) phase and lengthening the resting (telogen) phase. As hair follicles rest they begin to shrink and die. With Laser Hair Loss Control, there is no surgery involved. We simply offer a product line to use at home and a treatment program involving a series of sessions of therapeutic low light level lasers that cover your scalp in a non-invasive routine. You will see a reduction or slowing of your hair loss over weeks.
