I adore this shampoo. I have color treated, thin and fine hair, mid-length, and wavy. It tends toward "fuzziness" without the right products. I sometimes go to another shampoo but always see a difference when I come back to this. It really does help keep from stripping color and adds a little smoothness without flattening/stringiness. Be aware that it is sudsy but not to the degree of a lot of shampoos that strip your hair. Add more water (not more shampoo) to get more suds. The smell is very nice and neutral; it doesn't have the weird undertone that some of the other "green" shampoos have. I get crabby when I run out.....
