I was having a problem with oily hair. I tried several shampoos and none of them helped. My hair just felt gross and heavy. I was checking around online looking for a shampoo for oily hair at a reasonable price and I came across a review for this product. I know Paul Mitchell is supposed to make good products. My sister has one of his flat irons and it's amazing. So I thought I would give it a try. After literally just one use I noticed a difference. My hair is not oily any more and it feels soft and light. I would really recommend this product if you're having issues with oily hair or if you use a lot of products on your hair. It really does make your hair feel clean.
