Every purple shampoo tones brassiness. Only one eliminates the cause of it.
The K18 TripleBright Oxidation Defense Purple Shampoo is the first triple-action purple shampoo engineered to do what no traditional toning shampoo can: remove the metals and minerals responsible for brassiness, neutralize existing brass without staining or overtoning, and defend against future oxidation — all in one wash. The result is blonde that looks genuinely brighter, more vibrant, and longer-lasting between salon visits — not just temporarily toned.
Traditional purple shampoos work with basic colour correction: they deposit violet pigment to counteract yellow and orange tones. They don't address the root cause. Brassiness is primarily an oxidation problem — metals and hard water minerals accumulate on the hair fibre and oxidize over time, driving the warm, brassy tones that make blonde look dull and aged. K18 TripleBright targets all three stages of that problem in a single wash.
Available in 125ml and 443ml — choose the size that suits your routine.
KEY BENEFITS
- Removes up to 3 months of brass from hard water in 1 wash — ionic detox technology extracts accumulated metals and minerals from the hair fibre
- Neutralizes existing brassiness — precision violet technology corrects warm tones without overtoning, staining, or turning hair purple
- Defends against future brass — biopolymer technology helps prevent reattachment of metals and minerals during and after washing
- Works on all highlighted and lifted tones — brightens and evens ideal hair tone across the full spectrum of blonde shades
- Easy-to-apply foam format — expands from pump to foam for precise, mess-free application that reaches all areas evenly
- Will not turn hair purple — non-staining precision violet technology used as directed delivers toning without overtoning
- Will not stain hands or surfaces — rinses completely clean with water
- Leaves hair looking salon-fresh — restores vibrancy and brightness to colour-treated blonde with every wash
- Rated 4.9/5 across 260+ verified reviews — one of the highest-rated purple shampoos in the professional market
⚗️ K18 Triple-Action Technology — What Sets It Apart
Most purple shampoos do one thing: deposit violet pigment. K18 TripleBright does three:
1 — Ionic Detox (Remove) A targeted ionic chelating system that binds to and removes brass-inducing metals and minerals — including those deposited by hard water — directly from the hair fibre. One wash removes up to 3 months of hard water metal accumulation.
2 — Precision Violet Technology (Neutralize) A precisely calibrated violet pigment system that neutralizes existing brassiness and restores ideal hair tone without the risk of overtoning, purple staining, or uneven colour deposits. Hair is toned, not purple.
3 — Biopolymer Shield (Defend) A biopolymer that forms a protective layer on the hair fibre after cleansing, helping prevent metals and minerals from reattaching to the strand during and between washes — so brassiness develops more slowly over time.
Key Ingredients
| Ingredient | What It Does |
|---|---|
| Acid Violet 43 (CI 60730) | The precision violet pigment that delivers targeted toning without staining — calibrated to neutralize yellow/orange without overtoning |
| Trisodium Dicarboxymethyl Alaninate | A chelating agent that binds to and removes metal ions (including hard water minerals like calcium and magnesium) from the hair fibre |
| Sodium Phytate | A natural phytic acid derivative and powerful chelator that helps extract oxidative metals from the hair structure |
| Tetrasodium Glutamate Diacetate | An additional chelating agent that supports ionic detox and helps prevent metal redeposition |
| Sodium Polyaspartate | A biopolymer that helps form a protective barrier on the hair surface to resist mineral and metal reattachment |
| Sodium Gluconate | Supports the chelating system and helps stabilize the formula against metal-induced degradation |
| Polyquaternium-77 | A conditioning polymer that improves smoothness, reduces static, and supports the biopolymer protective layer |
| Cocamidopropyl Hydroxysultaine & Cocamidopropyl Betaine | Mild, foam-generating surfactants that cleanse gently and create the shampoo's signature lather without stripping |
| Sodium Cocoyl Alaninate & Sodium Methyl Cocoyl Taurate | Gentle, amino acid-derived cleansers that support effective cleansing while maintaining hair and scalp comfort |
| Glycerin | A humectant that helps maintain moisture balance during cleansing |
HOW TO USE: Apply 2–3 pumps of foam directly to wet hair. Distribute evenly, lathering from roots to ends — the foam format makes even coverage easy and mess-free. Leave in for 1–3 minutes — shorter for regular maintenance, longer for more pronounced toning or heavier brass correction. Rinse thoroughly. Follow with your favourite K18 conditioner or treatment.
Frequency: Use as needed — once weekly for regular brass maintenance; more frequently for heavily brassed hair or hard water areas.
Pro Tip — Leave time matters: 1 minute delivers a subtle refresh. 2–3 minutes delivers more pronounced brass neutralization. Start at 1–2 minutes if you're new to this formula, then adjust to your toning preference.
Note on the foam format: TripleBright dispenses as a foam, not a traditional liquid shampoo. Use 2–3 pumps — it expands significantly on wet hair. Pump onto palms, not directly onto hair, for best coverage.
❓ Frequently Asked Questions
How is TripleBright different from traditional purple shampoos? Traditional purple shampoos tone hair with basic violet colour correction but don't target the underlying cause of brassiness — oxidation from metals and hard water minerals. TripleBright's triple-action formula removes those metals, neutralizes existing brass, and defends against future accumulation, delivering a fundamentally different result.
Will TripleBright turn my hair purple? No. When used as directed, the precision violet technology neutralizes brassiness without overtoning or staining. Leave-in time affects toning intensity — stay within the 1–3 minute window.
Will it stain my hands or shower surfaces? No. The foam format rinses completely clean with water — no residue on hands, tiles, or towels.
Can I use TripleBright on any hair type? Yes. TripleBright works on all hair types and textures with highlighted or lifted tones — waves, curls, fine, thick, or coarse hair.
Can I use the Shampoo and Exfoliating Foaming Scrub together? Yes, for an extra-deep cleanse, but only when needed.
