The HairMax LaserComb is a medical breakthrough in hair loss and regrowth. In clinical studies, the HairMax treated hair loss and regrew hair for 93% of those who used it. Since 2001, the HairMax has helped hundreds of thousands of individuals regrow their hair safely and naturally. Laser phototherapy provided by the HairMax Professional 12 stimulates hair follicles, giving them the energy needed to promote hair growth and give you thicker, fuller, healthier hair. HairMax LaserComb Works for Both Men and Women. For many years, leading hair clinics and salons in Europe, Asia and around the world have been using "cold-beam" laser technology also known as "Low-Level Laser Therapy" (LLLT) to treat thousands of customers suffering from thinning hair. This is a chronic problem, requiring laser (or any other) treatment to be ongoing in order to maintain its effectiveness, so you"re constantly visiting a hair clinic or salon, and facing ongoing, often exorbitant, costs. Finally, there is a clinically proven solution and FDA approved (U.S. Food And Drug Administration). After rigorous clinical testing, the HairMax LaserComb® has been proven effective in over 90% of users. It is also safe, having been shown to cause no unwanted side effects and is free from on-going costs. The end result: medically significant clinical data and recent FDA clearance to market for the laser hair treatment solidifies the HairMax as a true revolution in the hair care industry.The HairMax LaserComb is the only Laser Phototherapy Device to be given clearance to market by the FDA for the regrowth of hair in males with certain classes of androgenetic alopecia.
