If you’ve ever struggled with dull, brassy blonde or unwanted yellow tones, you’ll know that not all purple shampoos are created equal. Enter K18 TripleBright Oxidation Defense Purple Shampoo — a science-backed innovation designed to go beyond toning and actually treat the root cause of brassiness.
At Luxe Hair Concepts, we’re always focused on results-driven, luxury haircare — and this is one of the most exciting launches for blondes, greys, and highlighted hair.
What Makes K18 TripleBright Different?
Unlike traditional purple shampoos that simply mask brassiness with pigment, K18 takes a triple-action approach:
- Removes buildup: Targets metals and minerals from hard water that cause dullness and discolouration in blonde, grey and white hair
- Neutralises brassiness: Uses precise violet pigments to counteract yellow and orange tones
- Defends against future damage: Helps prevent reattachment of minerals to keep hair brighter for longer
This means you’re not just toning your hair — you’re actively restoring clarity, shine, and colour integrity from the inside out.
The Science Behind Brighter Blonde Hair
Brassiness isn’t just about colour fade — it’s often caused by oxidative damage and mineral buildup from water, pollution, and environmental stress.
K18’s TripleBright technology works at the source by:
- Using chelating ingredients to bind and remove metals like copper and iron
- Restoring a more even, true-to-tone blonde
- Improving light reflection for visibly shinier hair
In fact, clinical claims show it can remove up to 3 months of buildup in just one wash, making it a powerful reset for blonde hair .

How to Use K18 TripleBright
For best results:
- Apply to wet hair
- Massage from roots to ends
- Leave on for 1–3 minutes
- Rinse thoroughly
Use once a week or fortnightly depending on your level of brassiness .
💡 Pro tip: This is a treatment shampoo, not your everyday cleanser — think of it as your at-home colour refresh.

Who Is It Best For?
K18 TripleBright is perfect for:
- Blonde, highlighted, or balayaged hair
