Technology or Key Ingredients

K18's Triple Bright Oxidation system targets three causes of dull, brassy hair: metal and mineral deposits, warm pigment build-up and oxidative damage that dulls colour. The formulation uses toning pigments in a lightweight foam base to neutralise yellows without depositing excess purple pigment, plus active stabilisers that help defend against future oxidation for longer-lasting vibrancy.

Professional Tips

• For stronger toning, increase leave time up to 3 minutes but avoid daily use—once weekly is usually enough.
• Pair with a nourishing mask or K18 leave-in treatments after rinsing to restore softness and manageability.
• Always perform a strand test if you’re unsure about desired tone, especially on very porous or heavily-processed hair.
• Use as part of a salon maintenance routine to extend time between colour appointments and reduce the need for corrective toners.

Results

With regular use, expect visibly brighter, cooler blonde and silver tones and a noticeable reduction in brassiness. Hair feels cleaner, softer and more luminous while colour remains protected from oxidation-related dulling.
