So.... When I did my training many moons ago, I learned that when colouring over blonde with brown, that you have to add some undertone which I get completely. But every time I do this it always comes out too warm. I've just done my friends hair tonight who was full head bleach highlights, her base is a really ashy level 6. I've just done a root stretch & used matrix 6n with a few cm of 6m & it's come out really warm! How can I make it ashy without going green? X
