To use Pink Warrior hair dye, first, patch test it on a small area of your skin to check for any allergic reactions. If you have level 10 blonde hair, the dye will give a vibrant glow under black light. For deeper pink hues, apply it to virgin, unbleached hair. Just follow the instructions on the package to apply the cream formula. After application, let it sit for the recommended time and then rinse it out. Remember, this vegan dye not only colors but also conditions your hair. It won't damage your hair; instead, it adds moisture to processed hair. After coloring, use a good quality conditioner to maintain the color and keep your hair healthy. If you experience any redness or itching during the process, stop using the product immediately.
