Key ingredients and why they matter

• Aqua / Eau — water base that safely dissolves and carries active colour molecules throughout the hair shaft.
• Hydrogen Peroxide — oxidative agent that opens the hair cuticle to allow pigment deposition for long-lasting colour depth.
• Cetearyl Alcohol — emollient that helps soften hair and improve glide during application, contributing to smooth, even coverage.
• Trideceth-2 Carboxamide Mea — conditioning surfactant that aids shampoo-like spreadability and helps maintain moisture in hair.
• Ceteareth-25 — emulsifier that stabilizes formula and enhances consistent colour distribution.
• Glycerin — humectant that helps attract and retain moisture for softer, more manageable hair after colouring.
• Phosphoric Acid — adjusts pH to help optimize colour uptake and conditioning balance.
• Tetrasodium Etidronate & Tetrasodium Pyrophosphate — sequestering agents that help prevent mineral buildup on hair, improving colour longevity.
• Sodium Salicylate — used to stabilize the formula and support even diffusion of pigment.
• Note: All ingredients are listed as provided in the product data and are intended to work together to deliver a vivid, lasting colour result.

Usage tips and suitability

Before colouring, perform the allergy test 48 hours prior to application. Apply to grey areas first and follow the suggested processing times based on grey coverage: 25 minutes for hair with little or no grey; add 15 to 20 minutes for grey hair. After colouring, rinse thoroughly and use the Shine Protect Conditioner, leaving it on for 2 minutes before a final rinse. This product is best for customers seeking a long-lasting, luminous permanent colour with reliable grey coverage.
