Preparation: Strict use of suitable disposable gloves is recommended. Do not mix or apply using any metallic tools. Use only with the recommended Dia Activateur oxidants.

Application and Development Time: Apply evenly to dry hair.
First application: The mandatory development time is 20 minutes, counted immediately after the application is finished.
Root touch-up: Apply directly to the regrowth area and start the 20-minute period. Then, distribute immediately to lengths and ends if a darker/deeper shade is desired; distribute after 10 minutes if the lengths show moderate fading; or emulsify during the last 5 minutes if slight fading is noted.
Emulsify and Rinse: Once the development time is complete, carefully emulsify the product by adding small amounts of water. Rinse hair thoroughly until it is free of residue and the water runs clear. Then wash with Metal Detox shampoo.
