I bought this shampoo, per my hairdressers advise, to preserve my blonde color. It does work great for preserving color. I could tell a significant difference in the length of time that my color lasted. It also made my hair shiny and seemed like it helped keep brassiness at bay. But, If you are looking for a shampoo to extend your color and give body to fine hair, this is not the one. I had to use a seperate volumizing conditioner and styling aid...
