Comb your hair (Combing your hair before bleach helps you to apply everything more evenly and smoothly). Bleach your hair up to level 8\9. Wash off bleach and dry your hair. If your hair is too yellow, use some purple or blue toner/shampoo that can help neutralize the yellow into white. Apply and leave it in for 5-10 minutes. That is important for pink hair colors so the yellowness won't turn the pink into orange or ashy orange. Apply a thick layer of hair color. Leave the hair color for at least two hours or more. You can go for hours or even overnight. The longer you keep it in, the longer the color will last, and the brighter will be the result. Rinse your hair with lukewarm water.
