I had an absolutely awful half head of highlights done in a salon a few weeks ago, made even worse when the same salon 'corrected' them. After a row I got my money back but had to pay more to get it sorted properly at a more reputable salon, but they warned me.at the time that the bleach would show through fairly quickly, and it has.
I can't afford to be going to the hair salon until this mess grows out, so I need to cover the whole lot over with a brown. A hairdresser friend says this should be fine, and will help me apply it, but I'm not sure about the colour. I don't think I'm brave enough for anything but brown, and apparently I need a warm tone. But how do I know what a warm tone is?
