I've been going to the same hairdresser for years for highlights....usually 2 colours.
I decided to have a change and went elswhere. 2 colours put on and then to my surprise toner was then appplied. I'd never had toner before. Hairdresser said it was just to reduce any brassiness. That scared me a bit!
Anyway the colour is lovely and I'm very pleased. Does anyone else have toner after highlights?
