COLORINSIDER is mixed in a 1:1 ratio of COLORINSIDER Precision Permanent Color to COLORINSIDER Oil-Cream Developer
COLORINSIDER Color must be mixed with the dedicated Oil-Cream Developer. As the developer and color have been specifically formulated to work together, COLORINSIDER will not perform as expected with another developer
PRO TIP:
The COLORINSDER Oil-Cream Developer has an exceptionally rich and dense consistency, specifically optimised for precise application. In order to make extracting the cream easier, store the bottle upside down using the COLORINSIDER helix once the developer is half-used. -
