I went a few shades lighter than normal, last time I had my hair coloured. Great to start with, but now, with 2 weeks to go til my next salon appointment, my roots look horrendous. My roots look black (even though they're not) against the too-blonde hair.
Is there anything at all I can do, as a temporary fix? I've tried hair mascara for dark roots, but the darkness is too dark to be easily disguised, if that makes sense.
