Every "color" shampoo I have used has either not cleaned my hair and left some kind of residue or it does nothing to prevent my color from fading. This shampoo cleans and clarifies AND protects my color. I'm 3 weeks into my color and it literally looks just as bright as it did the first day! I also love the smell. This is a heavy musky smell but it smells rich and luxurious! It's definitely a keeper!
