Using our Lunar Tides Petal Pink Hair Dye is easy. First, if you want vibrant results, bleach your hair to a pale yellow to platinum colour. Make sure the bleaching is even, especially if you have dark or previously dyed hair. Before applying the dye all over, do a strand test because the colour in the bottle may look different on your hair. Once you're ready, apply the dye following the instructions on the packaging. Since it's semi - permanent and non - damaging, you don't need a developer. After application, let it sit for the recommended time. To keep your beautiful petal pink colour looking great, use a colour - safe shampoo and conditioner. Avoid excessive sun exposure and frequent washing as these can fade the colour faster. Enjoy your long - lasting, glowing pastel pink hair!
