How do I get black hair dye out?

I've tried stripping it and it did come out but it got darker and darker every day til it went dark brown/black. So then I tried dying it light brown and it just got darker. So then I tried very light blonde and it got a little lighter but not very noticeable. So then I tried peroxide and it didn't do anything... I'm running out of ideas... Someone please help.How do I get black hair dye out?
