Do some strand tests first because you never know what rubbish people have put on their hair.
If you use a colour reducer to remove box dye build up, be prepared for it to take 2 to 3 goes to remove most of it and you’ll probably still need to use bleach to lift it to a 9 before toning.

If you’re not confident with colour removers, read this first to remind you of the process.
