I was just watching the news when this laser comb came on. It had just recently been appoved by the fda to actually work! Intrigued by this i went on there website to check it out....is this thing for real? anyone on her has actually tried it. The comb cost $500 plus bucks? I dont want to be a sucker to shell out the money for some dumb comb with a laser on it? Whats everyone else think?
