I would like to believe it but it seems too good to be true.
I got really excited about Gaunitz, but with further research I found out that they are a scam. All of their miraculous before and after photos were of men who were using the laser and rogaine + propecia. So Gaunitz definately is a scam despite the news coverage. Hairmax could very well be a scam too.
Think about it. If this laser could maintain or regrow hair like they claim, then everybody would be using it instead of paying $10,000 to go to a transplat surgeon. And its not like the laser is new. Its been around for quite some time yet there are very few good reports about it on these forums.
