Developed by NASA and backed by studies in Japan, Finland, Western Europe and the United States, low level light and laser technology actually promotes the appearance of new hair follicles with new hair growth. This technology has been introduced in an amazing device — the Power Grow Comb. This breakthrough has been discussed in major scientific conferences and associations around the world. Low Level Light and Laser Therapy doesn’t involve normal light. It is at a very specific wavelength, 660 nanometers, which can actually penetrate into the human skin. It increases capillary circulation in the scalp, bringing nutrients to the hair follicles. Plus, it actually energizes the cells, producing a bio-stimulating effect. Baldness occurs due to DHT attacking the hair follicles and making them shrink in size, eventually causing atrophia, alopecia and, unfortunately, baldness. Because this light phototherapy and it consequently increases capillary blood flow, it eliminates the DHT, as well as other wastes, allowing the hair follicle to expand and revitalize. This produces the appearance of hair follicles with new hair.
