K18 TripleBright Purple Shampoo for Blonde Hair - 4.2 fl oz Foam, Non‑Staining Tone + Metal‑Removing Protection

Hard water minerals, touch-up products and environmental oxidizers can make blonde and highlighted hair look dull, yellowed or brassy over time. K18 TripleBright combines ionic detox, precision violet pigments and a protective biopolymer to address the root causes of brassiness while brightening tone without depositing excess color. The formula comes as an easy-to-use foam so you can cleanse, clarify and tone in one simple step.

How does TripleBright remove the metals and minerals that cause brass?

Instead of simply masking unwanted warm tones, TripleBright’s ionic detox targets metal and mineral deposits that accelerate oxidation. In one wash, the system loosens and lifts deposits that build up from hard water and environmental exposure, helping restore a cleaner base for natural or colored blondes.

• Ionic detox ingredients chelate and lift metal ions from hair surface and strands.
• A single use can remove months’ worth of hard-water brass accumulation.
• Foam format spreads evenly for effective contact with mineral buildup.

Will it stain or overtone my hair like other purple products?

TripleBright uses precision violet technology that neutralizes yellow and orange without depositing heavy pigment, so it won’t leave a purple cast. The formulation is designed to correct tone while remaining non-staining and suitable for a wide range of highlighted and lifted shades.

• Precision violet pigments balance brassy yellows and oranges without overtone.
• Non-staining foam avoids the purple residue some toners leave behind.
• Safe for many blonde variations—from icy to honey highlights—when used as directed.

How does TripleBright help prevent future brassiness?

Beyond cleansing and toning, the product deposits a lightweight biopolymer that acts as a barrier to slow reattachment of metals and minerals during washing and exposure. That protective layer supports longer-lasting brightness and reduces how often you need corrective toning.

• Biopolymer forms a thin protective film on hair to reduce re-deposition of metals.
• Regular use helps maintain brighter, more consistent tones between salon visits.
• Compatible with color-treated hair and designed for repeated use in a routine.

How do I use the foam shampoo for best results?

Apply the foaming shampoo to thoroughly wet hair, working from roots to ends to ensure even coverage. Lather, let sit for 1–3 minutes depending on brass level, then rinse; follow with your regular conditioner or K18 treatment if desired.

• Dispense foam and apply to wet hair for even distribution.
• Leave on 1–3 minutes—shorter for maintenance, longer for stronger toning.
• Rinse and follow with conditioner or leave-in care as part of your routine.

Who is this for: K18 TripleBright is formulated for anyone with highlighted, balayage, bleached or naturally lightened hair who wants to remove metal-induced discoloration, neutralize warm tones without a purple cast, and protect color vibrancy between salon visits. It’s ideal for people dealing with hard water, frequent styling exposure, or anyone seeking a low-effort cleansing-and-toning step that fits into a regular haircare routine.
