Here at Giz we test a lot of gadgets, but it's not often we get to test them out on ourselves. Enter the HairMax laser comb. Thanks to my
dad's mom's genes and my soon-to-be-bald noggin', I'm the perfect guy to test it. So, what was it like? Well, it didn't burn, smoke, or sear my scalp (it's FDA-approved afterall). To be honest, I didn't feel a thing (not that you're supposed to). Though this I will say: My arm got tired very fast after holding it up for 15 minutes. We'll keep you updated on any, uh, growths. Otherwise, Gillette razor it is.
