I am seriously impressed with my color longevity while using this shampoo (and matching conditioner). Brilliance has both sodium lauryl and laureth sulfate at the top of the ingredient list, but my color retention is slightly *better* with the Brilliance line than when I used other salon brand sulfate-free color care shampoos. My thick hair is pixie-short and colored a reddish-copper brown, and I wash almost daily because of activity and styling products. This shampoo does not have a lot of grease-cutting power as it barely foams up if I try to wash out silicone styling serums, but it will lather up mild/moderately If I do a second washing (which I almost never do). I love how it gives my hair lots of shine, softness and natural texture, and also because it doesn't make my thick wavy hair poufy. Contains "liquid crystal technology" must be the diamond powder. Maybe that's what's making my hair shiny? I love the scent, too! It's a soft, neutral floral. I will replenish when it runs out.
