Setup, Compatibility & Care
Before starting, perform a patch test 48 hours prior to full application to ensure no allergic reaction occurs. Mix the color gel and the developer in a non-metallic bowl using a tinting brush. Ensure all equipment is plastic or glass to avoid unwanted reactions. After coloring, use a balancing shampoo and conditioner to seal the hair cuticle, which helps lock in the copper pigments and prolong the life of the color. Store the product in a cool, dry place away from direct sunlight, and ensure caps are tightly sealed if you have leftover product, although pre-mixed product should be discarded.
