Using this Blood Moon hair dye is easy. First, if you want the most vibrant color, bleach your hair to a pale yellow to platinum shade. Make sure the bleaching is even. After bleaching and letting your hair recover a bit, put on some old clothes and gloves. Apply the dye evenly to your hair, starting from the roots and working your way down to the tips. Leave it on for the recommended time on the package. Rinse it out thoroughly with cool water until the water runs clear. Remember to do a strand test before applying the dye all over, as the color in the bottle may look different on your hair. If you're bleaching your hair for the first time and have dark or previously dyed hair, take extra care to bleach it to the right color. To maintain the color, use a color - protecting shampoo and conditioner. Avoid washing your hair too often with hot water, as it can fade the color faster. Also, try to protect your hair from excessive sun exposure, as UV rays can also cause the color to fade.
