Goldwell Dualsenses Color Brilliance Shampoo is a color-protecting shampoo formulated for fine to normal color-treated hair, built around Goldwell's Fade-Stop technology, which is designed to help anchor color molecules in the hair and reduce fading with each wash. It cleans with a sulfate-based surfactant system (sodium laureth sulfate and sodium lauroyl sarcosinate), so despite sometimes being shelved near 'sulfate-free' products, it is not a sulfate-free formula.
The formula includes amodimethicone, a silicone that smooths the cuticle and adds shine, along with willow bark extract, panthenol, and glycerin for lightweight conditioning that won't weigh down finer hair. It's the lighter counterpart to Goldwell's Color Extra Rich line, which is formulated instead for coarse or thick color-treated hair.
