This vegan and cruelty-free wash-in color is formulated without ammonia to help hair retain its natural moisture. While available shades range from deep indigo to pale rose gold, those looking for a pastel color change will likely only see results if starting with already-lightened hair. But no matter what color intensity you're gunning for, Kandasamy suggests avoiding hot or warm water when rinsing the formula after application. "That will swell the cuticles, which allows the pigments to release, causing loss in shine and density of tone," he says.
