K18 Biomimetic Hairscience TripleBright Oxidation Defense Purple Shampoo

 

Keep blonde, silver, grey, and highlighted hair looking brighter, cooler, and salon-fresh with the K18 Biomimetic Hairscience TripleBright Oxidation Defense Purple Shampoo. Unlike traditional purple shampoos that only mask brassiness with violet pigments, this advanced formula targets the underlying causes of discoloration by removing mineral and metal buildup, neutralizing unwanted warm tones, and helping prevent future oxidation.

Powered by K18’s innovative TripleBright™ technology, this lightweight foaming shampoo deeply cleanses without stripping moisture or leaving hair feeling dry. Precision violet pigments instantly counteract yellow and orange tones while chelating ingredients lift away metals, minerals, and impurities commonly found in hard water that contribute to dullness and brassiness. The result is brighter, cleaner, softer hair with a more even, luminous tone after every wash.

Designed for color-treated and lightened hair, the formula helps preserve cool blonde shades between salon appointments while maintaining shine, softness, and overall hair health. Its non-staining formula rinses clean without leaving purple residue on the hair, hands, or shower, making it easy to incorporate into any blonde haircare routine.

It removes hard water minerals and metal buildup while neutralizing existing brassiness and helping protect hair from future oxidation. This multi-action approach delivers cleaner, brighter, healthier-looking blonde hair with long-lasting results, all without drying out the hair or leaving behind unwanted purple stains.
