Use the Best Conditioner on Color_Treated Hair : If you don't use aconditioner specially formulated for color_treated hair, you won’t get the results you want. Because color_treated hair has a different chemistry than its virgin counterparts, you’ll need to use a color_protecting conditioner. Conditioners with oils such as Tahitian monoi and those from the Ojon nut can help resist fading and create a protective barrier on color_treated tresses. In addition, there are conditioners that are formulated specifically to prevent premature fading in color_treated hair.
The last thing you want is to run out of dye halfway through the process. If your hair is shoulder length or longer, you may need two boxes to cover your whole head, depending on hair thickness. (And if you end up with a leftover box, you can always use it next time) Take the strand test : If you're trying a new shade, test it on a few trimmed hairs or hidden pieces first, and look at the result before you commit. A common horror story from testers who didn't do this: hair that turned orange and purple!
