Setup, Compatibility & Care
To prepare the product, mix the 60ml of Intercosmo Voila 3C with the recommended developer ratio—usually 1:1.5 for standard coverage—using a plastic mixing tool to avoid oxidation. Ensure your workspace is well-ventilated and protect your skin with a barrier cream around the hairline. For aftercare, use sulfate-free shampoos to maintain the integrity of the plum pigments. Avoid hot styling tools for 48 hours post-color to allow the pigments to stabilize within the hair shaft, and use a deep conditioning mask once a week to maintain the shine provided by the C3 formulation.
