Using the Lunar White Hair Toner is easy. First, if you have dark or previously dyed hair, bleach it to a pale yellow to platinum color. Make sure the bleaching is even. Then, do a strand test to see how the color turns out on your hair as the shade in the bottle can look different on your locks. If you're satisfied with the test, you can apply the toner all over your hair. This semi - permanent toner doesn't need a developer and won't damage your hair. After application, you'll get a long - lasting, glowing platinum white color. To maintain the color, avoid excessive sun exposure and use hair products suitable for color - treated hair. Remember, this toner works best on pale yellow hair, so keep that in mind for future applications.
