Editor's Take
A highly advanced approach to blonde maintenance that fights brass with smart mineral chelation rather than just heavy purple dye, trading clean chemistry for clinical-grade performance.

The Verdict
Most purple shampoos rely entirely on synthetic dyes to mask brassiness, but this blend takes a highly advanced route by targeting the root cause. It combines gentle amino-acid cleansers like Sodium Cocoyl Alaninate with a smart chelation system to pull dulling minerals out of the cuticle before they can oxidize your color. That highly effective performance comes at the expense of strict clean standards, leaning on standard ethoxylates and synthetic violet pigment to finish the job. Worth the investment for fragile lightened hair that needs serious mineral defense alongside gentle toning.
