I have mid brown warm coloured hair with a bit of grey. I had a permanent chestnut brown and some warmer caramel and coppery flashes put in a while ago. The sun has bleached the hell out of it and it looks really brassy. Help! Can I use a toner or a coloured conditioner to calm it down a bit? I only had the roots and a toner put in it 2 weeks ago and it’s gone back to brassy. It looked so good I could cry at how yellow it’s gone! I wash my hair every day which doesn’t help the colour stay. My hairdresser is on holiday or I’d ask her. Thanks!
