Hi I'm new to the site and have just worked out how to use it he he. Anyway I need some advice on a problem. I dyed my hair red at the begining on November which I hated so I went to a hairdresser and she said that she would dye it medium brown unfortunately it went black but has since faded to dark brown but I want to have it dyed to my natural colour of light brown. Is this possible or will it go green or something awful? Please help
