I have medium dyed brown hair and wanted blonde highlights. Went to a reputable salon today and they have RUINED my hair. The highlights looked horrible and didn't lift right so they've covered them with a light brown which is now ginger on top and green on the ends. I am so gutted. Obviously i haven't paid but i'm terrified of hairdressers now as this isn't the first disaster i've had and desperately want to fix my hair myself. What can I do? I'm sat here crying!
