TripleBright Oxidation Defense Purple Shampoo by K18 is the first triple-action formula for brighter, longer-lasting blonde.

K18 Triple-action purple shampoo for bleached and highlighted blonde hair

Traditional purple shampoos correct colour at the surface. TripleBright targets the root cause of brassiness: oxidation, and more specifically the metals and minerals present in tap water that accumulate on the hair fibre and progressively dull blonde tones.

Where conventional formulas deposit violet pigment to mask warm tones, TripleBright removes them, neutralises them and prevents their return, in a single wash, with no risk of overtoning or unwanted purple hues.

Its lightweight foam, easy to distribute from roots to ends, is built on three complementary technologies developed by K18: ionic detox, precision violet technology and a protective biopolymer.

Together, they deliver what no traditional purple shampoo can promise: results that last, colour that renews, and hair that stays healthy.

Clinical results of TripleBright Oxidation Defense Purple Shampoo

• 1 wash removes up to 3 months of hard water metals and minerals*
• Ideal hair tone restored and evened after 3 weeks of use at least once a week**

• Ionic detox – chelation technology that captures and eliminates the metals and minerals responsible for brassiness accumulated through hard water exposure; removes the equivalent of 3 months of buildup in a single wash
• Precision violet technology – neutralises existing warm and yellow tones with surgical precision, without depositing excessive pigment or risking overtoning or purple hues
• Protective biopolymer – forms a protective veil over the hair fibre to prevent metals and minerals from reattaching during future washes, defending blonde tone over time
• Sodium Polyaspartate – moisturising agent that preserves the suppleness and comfort of the fibre throughout the detox process
• Lemon & orange blossom oils – natural fragrance that brings a fresh, luminous scent signature to every wash
• Gentle plant-derived cleansing agents – cleanse effectively without stripping or drying colour-treated or bleached hair

Clean purple anti-yellowing shampoo suitable for all hair types and textures, across all blonde shades: natural, colour-treated, bleached, highlighted, balayage or ombré. Particularly recommended in hard water areas, to maintain blonde vibrancy between salon visits, and for anyone whose colour dulls quickly despite regular maintenance.

*Results reflect removal of hard water minerals and metals equivalent to three months of unfiltered tap water exposure on bleached tresses, based on scientific testing following 1 application of TripleBright.
**Results observed on 37 bleached/highlighted subjects after 3 weeks of use at least once a week.

How to use K18 triple-action purple shampoo for brighter blonde

Apply the foam to wet hair, distributing evenly from roots to ends.

Leave on for 1 to 3 minutes depending on the degree of brassiness, then rinse thoroughly.

Use once or twice a week in place of your regular shampoo to maintain blonde vibrancy over time.
