honestly,
I used the laser comb for three full months, and then started to lose confidence. All of the pictures on the site show rather impressive improvement at the 4 month mark, but the company only offers a 3 month return policy, though they will extend if most likely if you try to return it. Anyway, I cant afford to gamble on this product. The outright cost is too much for me to spend until I see some real quantitative data, i.e. , an FDA approval.
In short, did nothing for me in three months, and would have continued except for return time crunch, and lack of data yet. there you go....good luck to you though, cuz it works for some people apparently..
