Jul 27, 2012 - The leave-in, at first, was amazing. My curls defined in a way I have never seen before and it was flawless. Unfortunately my scalp would become extremely itchy, which has never happened before. So I looked at the ingredients and it was the amodimethicone that was the culprit, I have very sensitive skin so even though this works well, I'm knocking it a curl down. Besides, it smells of bathroom cleansing products.
