Can you tone your hair if you haven't bleached it?

Yes, you can tone your hair (regardless of whether it has been bleached or not) using a demi-permanent color mixed with 10 volume developer (You can find these things at Sally's or any other beauty supply store). If your hair is too brassy, or orangey, use an ash based color. If your color is too ashy, use a warmer color. If you plan on doing this yourself, visit a beauty supply store and the employees will definitely be able to help you choose the correct color! Good luck!
