I started using the lasercomb pro in October of 2013. By January 2014 I started seeing great results. My hair really thickened over the next few months. Starting in about September my hair started to revert back to the way it was originally when I started. I have continued to use the comb and have not changed anything but my hair continues to get thinner and thinner. I am not sure if this is common or if there is a problem with my comb. Any help would be greatly appreciated.
