Oxidizing Cream REF Cream Developer Peroxide 12% 40Vol

We recommend mixing all colors, including 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 application, mix in a well-ventilated area. The processing time and mixing ratio will depend on the product, hair color, porosity, and hair condition. Additionally, it will vary based on the technique used, the volume of hydrogen peroxide, and the number of levels to be lifted.
