I'm wondering if you gents can help me out. I seem to have chronically dry and flaky scalp. I have very thick hair but I use a ton of shampoo every day, maybe miss a day here or there and still flakes. I use head and shoulders for dry scalp and I have used selson blue with slightly better results but wonder if there is something I am missing. The fact that I shaved with canned goop for so many years makes me think I may be missing something in hair care as well. Thanks so much.
