READ THE DIRECTIONS
My hair is extremely thick, curly, and my scalp gets very dry.  I wasn't entirely sure how this shampoo would work, but I'm glad I bought it. If you follow the directions on the back you should have expected results after the second wash, although every hair texture is different. I would say after the third or fourth wash if you don't see a difference I would try to return it.
