Ok so I’ve been growing out my grey hair for a few years. A few months ago I realised how much it was ageing me & decided to box dye it using Nice N Easy Demi-permanent medium ash blonde. I didn’t love the colour (I was hoping for a dirty blonde but it was definitely more chestnut) but decided it was better than the grey. I’ve redone the colour twice since & it’s basically turned my hair an horrible brassy orange. What can I do? I can’t afford to have a hairdresser put it right but I’m clueless about how to get it to where I want it to be. Do I try dying it a different colour? Blue shampoo? Toner? Help me!
