Using this Manic Panic hair color is easy. First, if you want the purest Violet Night color, bleach your hair to a level 9 or 10. Then, apply the cream formula evenly to your hair. Leave it on for the recommended time as stated on the package. After that, rinse it out thoroughly. Before using the product for the first time, always do a patch test on a small area of your skin. Just put a little bit of the color on your skin and wait for 24 hours. If you notice any redness, itching, or discomfort, don't use the product. To maintain the color, try to wash your hair less frequently with cool water and use a color - safe shampoo. This will help the color last longer and keep your hair looking great.
