Sulfate-free for color-treated hair
Sulfates open the hair cuticle significantly with every wash and strip out color pigments wash after wash. A sulfate-free shampoo bar with a gentle coconut-derived surfactant cleanses the scalp without disturbing the cuticle, helping the color last longer and keeping the hair shiny.
Color doesn't just sit on the hair. It sits inside it. And every time you wash with a shampoo containing sulfates, the cuticle opens so much that color pigments gradually seep out, wash after wash, until the color is a shadow of its former self. It isn't inevitable. It's a product choice.
What do sulfates do to colored hair?
Sulfates such as SLS and SLES are strong surfactants that significantly open the cuticle with every wash. For colored hair, this means that color molecules leach out faster, the hair's natural lipid barrier breaks down, and the hair becomes drier and more porous with every wash. The result: the color fades, the shine disappears, and the hair feels rough.
Why a sulfate-free shampoo bar is better
A sulfate-free shampoo bar uses milder surfactants that effectively cleanse the scalp without disturbing the cuticle or stripping out color pigments. The hair retains its natural oils, moisture stays locked in, and the color lasts longer between coloring treatments.

Combine it with the right conditioner and hair mask
Sulfate-free shampoo is the foundation, but colored hair needs more. Always complement it with a conditioner bar for colored hair and a hair mask once a week for deep hydration and color protection.
