Although I love some of Paul Mitchell's other products, this one is not for me. Right away I noticed a fragrance of which I was not fond. While shampooing, I did not notice anything particularly great about this shampoo, which targets swimmers to help with removal of chlorine and impurities. Perhaps noticing an effect would take multiple uses of the shampoo? The fragrance in the shampoo caused me to develop a headache - so if you have sensitivities to fragrances, I would not recommend this product for you. I am unable to judge whether it delivered on its promise of "clarifying", since I was only able to use it the one time.
