Setup, Compatibility & Care
Before starting, ensure you have an old towel to protect your clothing and a non-metallic bowl and brush if you prefer manual application. The dye is compatible with most hair types, though it is strongly recommended to conduct a patch test 48 hours before use to ensure you do not have an allergic reaction. To maintain the intensity of your Cosmic Blue color, use a color-safe shampoo and avoid excessive heat styling, which can strip pigments over time. Keep the product stored in a cool, dry place away from direct sunlight when not in use.
