I have been asked by many clients about my professional opinion regarding the use and effectiveness of the Hairmax Laser Comb and its effectiveness in hair regrowth. My observations over the past two years have been very positive with its effectiveness when used as directed. I have personally observed slight to moderate regrowth on over 90% of the clients who have purchased the comb, who come to our salon on a regular basis for hair services. Clients themselves are the biggest advocates, stating their hair is not only growing in, but has also become more manageable, with added sheen. The laser comb works well in preventing further hair loss, and the sooner one gets started with the laser therapy the better. The Hairmax laser comb is the only hand held laser device that is cleared by the FDA for safety. All laser combs are not created equal and should be scrutinized before a purchase is made. The laser device must be cleared by the FDA so you know that it meets the guidelines for safety and effectiveness. The device utilizes cold laser that increases blood flow to the hair follicles, and stimulates hair re growth of the dormant hair follicles. There have been no known side effects from using cold laser for hair growth when used according to the manufacturers instructions. Laser therapy was developed by a physician in Australia over 20 years ago and has been proven to be a safe way to stimulate new hair growth.
