Setup, Compatibility & Care
Before you begin, ensure you have a plastic mixing bowl, a brush, and an old towel to protect your clothing. Perform a skin allergy test 48 hours prior to full application. For care, wash your hair with lukewarm water rather than hot to prevent the metallic pigment from fading prematurely. Use color-safe shampoos that are sulfate-free to maintain the vibrancy of the blue tones. If your hair is currently processed or chemically damaged, consider a deep conditioning treatment a week before applying the dye to ensure the color lays evenly and lasts longer.
