Dd has been bleaching her hair using L'Oreal. She's used a couple of kits over the last few months. The last one she used was called Champagne Blind. Now her naturally mid blond hair looks a little yellow, not a nice colour at all 
I can't afford to take her to a salon so I need some colour advice. What can she put on her hair to tone the colour down and take it back to a more natural colour. She's worried that any remedy will make her hair too dark.
