A next-generation purple shampoo that does more than tone! This advanced formula targets the root cause of brassiness for brighter, cleaner, longer-lasting blonde. Powered by K18’s triple-action technology, it removes mineral and metal build-up, neutralises unwanted yellow and orange tones, and helps prevent future brassiness. The unique foam texture makes application easy and even, delivering a fresh, luminous finish without staining or over-toning. Perfect for blonde, highlighted, or lightened hair needing a true reset.
