Precautions: wear disposable gloves. Do not use metal objects for the application (bowl, comb, tweezers...) to Mix until mixture is homogeneous and creamy. Stick to the proportions given. Application and rinsing: Apply with a brush on dry hair and not washing. Split and hair in four sections, following an imaginary line from the forehead to the nape of the neck and another line from one ear to another. Start the application from the area with greater presence of gray hairs. If there are no visible differences, starting from the top of the head. Exposure time: Process 35 minutes at room temperature, 45/50 minutes to the superaclarantes. Over this time, emulsify and rinse hair until the water runs clear. Use the specific shampoo for coloured hair.
