Instruction: Mix Profix bleaching powder with a developer/oxidizing cream at a ratio of 1:2 or 1:3, depending on the consistency you wish to achieve. In a non-reactive bowl, mix the bleaching powder with Oxydant Cream 20, 30 or 40 volume until you have a smooth cream. The cream will thicken somewhat within the first 1-2 minutes; simply add some more hydrogen peroxide. Apply the cream evenly to unwashed hair or strands. Leave on hair for approx. 15-40 minutes, depending on the level of lightening you wish to achieve. Then rinse the cream out thoroughly and wash your hair using a mild shampoo. Subsequently, apply conditioner. Caution: Contains hydrogen peroxide. Keep out of the reach of children. Avoid contact with skin and eyes.
