Setup, Compatibility & Care
To begin, ensure you are working in a well-ventilated area and utilize professional tools like a tint brush and a non-metallic mixing bowl. The 8.4/8C shade is designed for use on pre-lightened or natural light hair; results may vary significantly on darker hair tones, so a strand test is recommended before full application. For care after the dyeing process, use a color-safe, sulfate-free shampoo to maintain the longevity of the copper pigments. Always follow the specific mixing ratio provided in the instructions for the developer to ensure the chemical reaction activates correctly for optimal color deposit.
