Hey man,
Yes I would say that the comb has helped with irritation. My scalp feels great all over. It used to itch and was somewhat bothersome. However, now it feels "alive". That sounds stupid, but that is the best way I can put it. Whether it will help with your problems I can't answer that. The degree to which it helps with irritation probably varies from person to person. However, the lasercomb is supposed to help with inflammation and irritation. I have also heard many reports of it helping with dandruff. Hope that helps!
