K18 TripleBright Oxidation Defense Purple Shampoo125 ml
K18 TripleBright Oxidation Defense Purple Shampoo is an advanced, non-staining purple shampoo that removes brass, restores brightness, and protects blonde hair from future discolouration. Powered by triple-action technology, it removes metals and minerals, neutralises unwanted tones, and helps defend against future brassiness for cleaner, brighter blonde in just one wash.

Why you need it
K18 TripleBright Oxidation Defense Purple Shampoo goes beyond traditional purple shampoos by targeting the root cause of brassiness, oxidation from metals and minerals in water. Instead of simply masking yellow tones with pigment, this purple shampoo works in three ways to restore and maintain a fresh, bright blonde. Ionic detox helps remove brass-causing metals and mineral build-up from hard water, while precision violet technology neutralises existing brassiness without staining or overtoning the hair. A biopolymer then helps defend against future brass by reducing the reattachment of these impurities during washing. In just one use, it can remove up to three months of brass, leaving blonde, highlighted or lightened hair looking cleaner, brighter and more even. The lightweight foam texture makes it easy to apply and target specific areas, delivering a more controlled, mess-free toning experience with visibly brighter results.
