Do you know your hair's properties (texture, porosity, etc.)? What products are you using? Did you do a final sulfate wash? Some people need weeks or even months for their hair and scalp to really adjust to CG. Or it could just be that you're using something that your hair doesn't like. If you give us a little more info I'm sure that there are lots of people who can answer your questions.
