How to


Use exclusively with the recommended Diactivateurs 6 vol. (1.8%), 9 vol. (2.7%) or 15 vol. (4.5%) maximum. Do not use with hydrogen peroxide greater than 15 vol. (5.7%). Use only the proportions indicated. When a bottle is used, open immediately after mixing to avoid the shaker bursting and damage from the product overflowing. For each application, mix the Dia color cream and the developer (mix 1+1.5). Mix with a whisk or a bottle until a homogeneous texture is obtained.


Wear appropriate single-use gloves. Do not use metallic objects (clips, combs...). 1st application: on dry, unwashed hair, apply with a bowl & brush or a bottle on the roots, lengths and tips. Development time: 20 minutes. Subsequent applications: apply the mixture only to the roots and leave on for 15 minutes. Then apply to the lengths and ends and leave for 5 minutes. In some cases, refreshing with a simple emulsion is sufficient.

Emulsion and rinsing

After the development time, emulsify carefully for a few minutes. Rinse well until the water is clear. Finish with Metal Detox shampoo.
