I've had another terrible colour. Black base with dull yellow / white stripes through it. Will be going over it with a warmer box colour shortly.
I have grey hair. It used to be dark brown, almost black. There are still some bits of the natural colour at the back.
Every time I go to a hairdresser, I point out that as it's grey, they don't need to attempt to dye it back to its original colour because it's aging. I'd like a medium brown with golden highlights through. This seems to be beyond them though.
