To use this Lime Crime Unicorn Hair Tint, first gather your supplies: gloves, clips, an applicator brush, a bowl, and an old t - shirt or cape. Cover any surfaces you don't want to get stained as the dye can permanently stain them. Start with clean, unconditioned, dry pre - lightened platinum to pale blonde hair. Put on the gloves and pour the desired amount into the bowl. Section your hair into 4 equal parts and secure them with clips. Work in 1 - inch wide strands, applying the color evenly from root to tip with the brush. Massage each strand to make sure the color is spread evenly. Leave the tint in for 45 minutes. For more intense and long - lasting results, leave it in for 1 - 2 hours. There's no need for heat or a cap, and don't worry, it won't damage your hair as it has no harsh chemicals or bleach. Rinse your hair in cool to lukewarm water until it feels clean. Some intense shades may not rinse clear right away. You don't have to shampoo, but using a conditioner is optional. Style your hair as you like and enjoy your new unicorn look! Always do a patch and strand test first to check for any skin irritation and to find the color saturation you prefer. This product is ready to use, so don't mix it with developers, lighteners, or permanent hair colorants. It may stain your skin temporarily and fabric permanently, so protect your clothes and workspace. Keep it out of reach of children and don't use it on your face, near your eyes, or for dyeing eyelashes and eyebrows.
