I had my hair dyed a month ago. It was the 3rd time I've been to this hairdresser; the first two times I was really happy with the root touch up plus low and high lights. This time she was in a rush as accidentally double booked so I said just the roots would be fine this time. Anyway it was darker than usual (and had dye on my towels 2 days later) but has now faded to this gingery tone which makes my roots look almost greasy when freshly washed. My grey roots are also much more visible. The longer lengths are fine. I should have gone back to complain at the time but didn't and now I have a party this weekend with no time to see a hairdresser (a different one...) . I have used box dyes before but I'm a bit concerned about all the different colours on my noggin at the moment. Any recommendations?
