Studies show that regular use of LLLT to help stop hair loss and promote hair regrowth is possible and promising. FDA-cleared LLLT devices, like HairMax's, were safe and effective in treating both men and women who did not respond to standard hair loss treatments.

Treatment with the devices can cause some users to experience shedding during the first few weeks of use, as the laser energy causes the hair follicle to shed damaged hairs and regrow healthy ones. Shedding is actually a positive sign that the HairMax laser device is beginning to work to regrow new, healthy hair.

So while some grey haired people who have reported that the HairMax worked great in stimulating hair follicles and regrowing their hair, some say that the hair that they was regrown, came back dark!
