Oxidizing Cream REF Cream Developer Peroxide 1.9% 6Vol

We recommend mixing all colors, as well as Blonde.ID Bleach, in a non-metallic bowl with REF Cream Developer, using a non-metallic whisk to achieve a smooth consistency. As with any color treatment, mix in a well-ventilated area. The processing time and mixing ratio will depend on the product, hair color, porosity, and hair condition. It will also vary based on the technique used, the volume of hydrogen peroxide, and the number of levels being lifted.
