I've been experimenting with a laser to see if it will help my hair. At the moment I'm just testing out an old laser pointer that I bought before I step up and get a laser comb or the likes. I noticed when I use the laser pointer I can feel a distinct tingle especially if my hair is wet. I don't know if it's accomplishing anything, but it's got my attention. However, I read the laser are used for hair removal which didn't really bother me because those are much higher power, but one of my friend's who works at a checkout in a super market claims the part of his forearm is bald because of the scanning laser. I don't know how powerful it is but I'm kind of hesitant with lasers. Any experiences with lasers?
