If you're talking about hair dye, no don't wash your hair. Color stays on better if your hair is dirty when you apply it.I just bought the revlon cap for medium brown ... and i was wanderin do u wash your hair before using it ?
no! shampoos and conditioners put a ';coating'; on your hair. if you wash it and then put dye in it, the dye will not permanently dye it. the dye will just come out during the next wash because it didn't really soak into the hair.
