I really like the manageability I get after using this shampoo. The scent is pleasant. The only reason I gave it an 8 is because it is a bit expensive, so I only buy it when I can find it on sale at the local drug store or grocery store. I have only used the shampoo with a color-treated hair conditioner, so I can't speak to how manageable my hair would be without using a conditioner following the shampoo with this product. Effectiveness I think it cleans well, but I am unsure how to gauge whether or not it makes my color last longer than if I didn't use it. I am hoping that it does keep my color, as the product information claims it will. So far, the color does not seem to fade or change between hair coloring treatments which I do myself approximately every two to three months, and I do have those color-resistant greys that usually only show in the new root growth so I do think the shampoo helps keep the color true. Scent The scent is pleasant.
