I've put a pastel pink hairdye on. The Schwarzkopf one that lightens it 2 shades too. Have used it before a few years ago no problem so wasn't expecting any issues.
However, my roots are now bright ginger! I've realised what's happened is most of my hair is already pre lightened but I had about 2 inches of root regrowth which is medium brown naturally but now heavily grey so I thought the pink would just go over it all ok.
I can't get to the hairdressers until next month so I need help now! Do I do it again and leave it on the roots longer to pre lighten them more or will it make it worse? I've tried purple shampoo and not helped a great deal.
