Key benefits

• Fade-defying colour that stays vibrant for up to 8 weeks.
• Instantly revives first day luminosity, giving a fresh, glossy look from the first application.
• Targeted grey coverage by applying the mix first to grey areas and processing accordingly.
• Complementary Shine Protect Conditioner helps lock in colour and smooth the hair after colouring.
• Allergy test recommended 48 hours before colouring to ensure compatibility with your skin.

Ingredients and why they matter

• Aqua / Eau — the solvent that carries colour components evenly through the hair shaft.
• Hydrogen Peroxide — oxidizing agent that opens the hair cuticle to allow colour deposition.
• Cetearyl Alcohol — conditioning fatty alcohol that helps soften and protect the hair during processing.
• Trideceth-2 Carboxamide MEA — a conditioning and emulsifying agent that aids in smooth application and even distribution.
• Ceteareth-25 — helps blend the formula for uniform coverage and feel.
• Glycerin — humectant that helps maintain moisture, reducing frizz and improving manageability after colouring.
• Phosphoric Acid — helps balance pH to optimise colour deposition and scalp comfort.
• Tetrasodium Etidronate & Tetrasodium Pyrophosphate — chelating agents that help prevent mineral buildup, supporting even colour results.
• Sodium Salicylate — stabilises the formula and can aid in keeping the mix consistent during preparation.
