Urgh, just coloured it (using a Schwarzkopf permanent dye and left it on for longer than it said) and the bloody roots are still a patchy grey. Any recommendations? I've just bunged on some nice & easy root touch up, but even that doesn't seem to work as well anymore now I'm very, very grey at the front and top.
We do have a Sally's in town if they might have something better, although I probably can't get there until next weekend.
I can't afford to have it done every three weeks at the hairdressers (it grows fast). Please help.
