Ingredients and why they matter

Aqua / Eau — acts as a solvent to carry the colour into the hair shaft. Hydrogen Peroxide — acts as the oxidative agent that opens the hair cuticle to allow colour deposition. Cetearyl Alcohol — provides conditioning and helps form a stable, creamy texture for even application. Trideceth-2 Carboxamide Mea — a surfactant that aids in spreading the formula evenly. Ceteareth-25 — helps emulsify and stabilize the product. Glycerin — humectant that helps maintain moisture in the hair. Phosphoric Acid — maintains the formulation pH for safer, gentler processing. Tetrasodium Etidronate & Tetrasodium Pyrophosphate — chelate minerals to avoid impurity interactions, supporting uniform colour. Sodium Salicylate — helps maintain formula stability. These ingredients work together to deliver consistent colour deposition, conditioning, and a healthy-looking finish.

Usage guidance and who it’s for

This product is designed for adults seeking permanent hair colour with a fade-defying finish. The included steps emphasize a thorough application process to ensure grey areas are covered and colour develops evenly. A skin allergy test 48 hours prior to colouring is advised to minimize irritation. Do not exceed the recommended processing times stated in the steps below, and always rinse completely before applying the Shine Protect Conditioner. Store the product as directed on the packaging and keep out of reach of children.

Recommended for those who want a reliable brown shade with long-lasting vibrancy and a high-shine finish. Those with grey coverage needs will benefit from applying the formula first to grey areas and following the suggested timing. Always perform the allergy test and follow the included usage steps for the best results.
