K18 TripleBright Oxidation Defence Purple Shampoo
Three-action foam toning shampoo for blonde and lightened hair
K18's answer to brassiness in lightened or colour-treated hair. TripleBright uses a three-phase approach: ionic detox to remove brass-causing metals and minerals (including up to three months' worth of hard water copper in one wash), precision violet technology to neutralise existing warm tones without overtoning, and a biopolymer shield to help prevent metals and minerals from reattaching in future washes. A foam format rather than a traditional shampoo consistency. Launched in 2025. Designed for use one to two times per week, alternated with the DAMAGE SHIELD or PEPTIDE PREP shampoo. Surfactant profile places it in cgm_modified territory. Most relevant for bleached or highlighted curlies dealing with brassiness alongside structural damage.
