Using this Lunar Tides Coral Pink hair dye is easy. First, if you want vibrant results, bleach your hair to a pale yellow to platinum color. Make sure it's evenly bleached, especially if you have dark or previously dyed hair. Before applying the dye all over, do a strand test because the color in the bottle might look different on your hair. When you're ready, apply the dye following the instructions on the package. Since it's a semi - permanent and non - damaging dye, you don't need a developer. After application, let it sit for the recommended time. To maintain the color, use color - safe shampoos and conditioners. Avoid excessive sun exposure as it can fade the color faster. Enjoy your beautiful coral pink hair!
