Ingredients and how they matter

• Aqua / Eau serves as the base solvent to help create a smooth, even application across the hair shaft.
• Hydrogen Peroxide provides the lightening action that opens the hair cuticle to allow color molecules to deposit for lasting coverage.
• Cetearyl Alcohol acts as a conditioning emollient to help keep hair soft during and after color processing.
• Trideceth-2 Carboxamide Mea and Ceteareth-25 assist in emulsifying and stabilizing the formula for uniform color distribution.
• Glycerin helps maintain moisture to reduce dryness during coloration.
• Phosphoric Acid helps adjust pH for optimal color uptake and stability.
• Tetrasodium Etidronate and Tetrasodium Pyrophosphate act as chelating agents to help protect color integrity and improve rinse-out performance.
• Sodium Salicylate assists in preserving formulation quality and feel during use.

How to use and who it’s for

• Allergy test should be performed 48 hours before colouring to check for reactions.
• Apply product using the applicator, squeeze colour mixture immediately to dry, unwashed hair. Work gently through hair as you would a shampoo, and apply to grey areas first.
• For hair with little or no grey, wait 25 minutes with the mixture in your hair. For grey hair, leave on for an additional 15 to 20 minutes.
• Rinse out. Add a small amount of warm water to hair and work into a lather. Then, rinse with warm water until water runs clear.
• Apply the Shine Protect Conditioner and massage through hair. Leave on for 2 minutes before rinsing through with warm water until the water runs clear.
