Ingredients and what they mean for you
- Aqua / Eau — water base that dissolves colorants and helps distribute the formula evenly through hair.
- Hydrogen Peroxide — oxidizing agent that enables the depth and permanence of the hair color in the formula.
- Cetearyl Alcohol — conditioning thickener that helps soften hair and aid in even application.
- Trideceth-2 Carboxamide Mea — surfactant that improves the spread and foaming of the tint for uniform coverage.
- Ceteareth-25 — emulsifier that stabilizes the mixture for consistent results during processing.
- Glycerin — humectant that helps maintain moisture in the hair for a smoother finish.
- Phosphoric Acid — acidifier that adjusts pH to optimize color uptake and cuticle sealing.
- Tetrasodium Etidronate and Tetrasodium Pyrophosphate — chelating agents that help remove minerals from water to improve color performance.
- Sodium Salicylate — salt form that can influence texture and processing of the color mixture.
- Allergy test 48 hours before colouring is recommended to ensure compatibility with your skin.
Usage and suitability
