My hair is horrible in the humidity so when I saw that Tresemme had released this system, I was excited. I went and bought the shampoo and conditioner immediately. Yet once I tried it, I realized it does not work at all. It does smell nice, but other than making your head smell great, there was absolutely no change in my hair's condition after using this. I thought that maybe I hadn't used it long enough so I used it for a while longer, but again, did not get the results they claim you will receive. I eventually stopped using the products and switched to another shampoo/conditioner even though I had half the bottles left.
