Quick question on usage. I purchased the original 9 Hairmax laser comb a few years ago but have never used it on a regular basis. I have decided to stop using chemicals and pills and was going to just use the laser comb. Some local salons state that the comb can't be as effective as their laser hoods based on the fact that it is one laser bounced of a mirror 9 times; and if I wanted to equal the lasers 20 minute session at the salon I would have to use the comb for over 400 minutes. My question is have you change the tech since the original?
