I buy this shampoo over and over again. I've tried the purple conditioner and thought it was pretty good. I heard there was a treatment for color-damaged hair, so I bought it. It's an unusual shampoo that requires you to rub the concentrate directly into your scalp and hair, then lather it up and wash. It leaves a refreshing feeling during and after shampooing. However, my hair tends to get a bit rough and tangled after shampooing. This conditioner quickly solves that. Compared to the purple type, it seems to leave my hair feeling a little more moisturized. I squeeze out the water and use about two cherries' worth of product for chin-length hair. It becomes smooth as it soaks in. It also adds shine and makes my hair more manageable. My hair feels stiff after using a leave-in bath, so I try not to put anything on it after washing, but it still leaves my hair feeling pretty good. It adds shine and manageability, especially the next morning. My hair is soft and slightly thin, so I'm not sure if continuous use will keep it from becoming flat. I might add more in the future.
