Just wondering if anyone has used something like Majicontrast with grey hair? I'm after a complete change. Getting the bleached bits cut off in a few days and I'm fancying going pillar box red. BUT ! My hair is dark brown and a LOT of it has gone grey. (Getting old sucks). More than 50% grey. I stumbled upon Majicontrast online, along with instructions to mix it with creme peroxide so that it will work on dark hair. But what about when your hair has got a lot of grey in it? None of the stuff I've read online is by anyone with some grey hair. Please help !
