Question: do i need to wash my hair before applying toner?
Answer: Generally speaking a toner is applied right after a bleaching process and the Wella Toner line directions say to not use shampoo or conditioner prior to use. ... If so yes but only use shampoo. If not and you're just toning your hair then you don't need to wash it before, you'll need to wash it after to get the toner out.
