I can tell that the weather is changing. My scalp reacts! I get very dry skin, not dandruff, but cracking, bleeding, etc. It is quite unpleasant and I want to use something natural. My hair dresser last year gave me some chemically stuff for my scalp. I use Nature's Gate Tree Tea oil shampoo and conditioner and also a Jason's brand too. It seems like nothing works. I have tried the natural dandruff shampoo, but that doesn't help because my situation is not dandruff. I only have this problem when the weather starts getting cooler.
