Query: itchy afterwards

My scalp was itchy from time to time but nothing severs. I thought to try the shampoo after reading all the reviews. Well it arrived new, fast & as described. When I went to use it, my scalp felt very dry & itchy afterwards. I thought maybe it was to get worse to get better so I used it a 2nd time and it made my scalp start to flake! Ok that's it I stopped using it.
