TripleBright Oxidation Defense Purple Shampoo is a breakthrough, triple-action formula designed to keep blonde hair brighter, fresher, and like new for longer. Powered by advanced K18 triple-action technology, it works on multiple levels to restore and protect tone. Its ionic detox system helps remove brass-inducing metals and minerals—often caused by hard water—effectively lifting away buildup, with just one wash capable of eliminating months of brassiness. Precision violet technology then neutralizes unwanted warm tones without staining or overtoning, ensuring a balanced, natural-looking blonde across all highlighted and lifted shades. Finally, a protective biopolymer helps defend against future brassiness by preventing metals and minerals from reattaching during washing. The lightweight, easy-to-apply foam glides effortlessly through hair, restoring ideal tone while leaving it even, clean, and refreshed.
