K18 Biomimetic TripleBright Oxidation Defense Purple Shampoo - 4.2 oz

Experience the next evolution of blonde maintenance with K18 TripleBright Oxidation Defense Purple Shampoo, a high-performance foam cleanser that goes far beyond simple color correction. This isn't your average "staining" purple shampoo that leaves your bathroom tiles—and your hair—tinged with unwanted violet. Instead, it utilizes a sophisticated Triple Action Technology that acts as a precision strike against brassiness. By combining an ionic detox with precision violet technology, it effectively lifts away the heavy metals and mineral buildup from hard water that cause blonde tones to dull and shift over time.

The unique foam delivery system ensures an incredibly even distribution, saturating every strand from root to tip without the patchiness often found in thick, liquid pigment shampoos. This airy, cloud-like lather doesn't just neutralize current yellow tones; it builds a protective biopolymer shield to defend against future oxidation and environmental stress. Your hair isn't just "toned"—it’s clarified and brightened, restoring that fresh-out-of-the-salon luminosity that usually fades within weeks. It’s the ultimate "reset button" for highlights, balayage, and silver hair, providing a clean canvas for your other K18 molecular repair treatments to work more effectively.

Unlike traditional toning products that can leave hair feeling like straw, this biotech-driven formula prioritizes the health of your hair fiber. It’s infused with a refreshing, multi-layered scent profile featuring bright notes of blood orange and grapefruit, grounded by a sophisticated base of cedarwood and tonka bean. The result is a sensory, spa-like experience that leaves your hair feeling soft, bouncy, and remarkably vibrant. Whether you're battling the effects of well water or just want to keep your platinum crisp, this 4.2 oz powerhouse ensures your color stays as intentional and brilliant as the day it was created.

The revolutionary Triple Action Technology provides a three-pronged approach to hair health by removing brass-inducing metals, neutralizing yellow tones, and defending against future oxidation. This holistic method ensures your blonde stays bright and clear for longer, rather than just temporarily masking damage with purple pigment.

In just a single wash, the ionic detox feature is scientifically proven to remove up to three months of mineral and metal buildup caused by hard water. This deep-cleansing action instantly restores the vibrancy of your highlights, making it an essential "rescue" product for dull or shifting hair colors.

The easy-to-apply foam consistency allows for a perfectly uniform application that eliminates the risk of over-toning or leaving unsightly purple stains on the hair and scalp. Because it spreads so evenly, you achieve a balanced, professional-grade result every time you use it, regardless of your hair’s porosity.

Powered by a defensive biopolymer, this shampoo creates an invisible barrier that prevents new metals and minerals from reattaching to the hair shaft during subsequent washes. This proactive protection means you spend less time fighting brassiness and more time enjoying a luminous, cool-toned aesthetic.

Infused with the signature K18 biotech approach, this formula is pH-optimized and gentle enough to maintain the integrity of your hair’s natural protective barrier. It leaves your strands feeling soft and manageable rather than dry and brittle, making it the perfect companion for the K18 Molecular Repair Mask.
