Hair turned Gray. What do I do?

I previously had tried to dye my hair platinum blonde and ended up really brassy. My roots came in and I tried to turn it back to a dirty blonde. Of course instead it turned grayish. 1 how can I get rid of the gray?2 would it be easier to go back to the blonde somehow? I would prefer that.

It is difficult to give an answer with the information provided. Was your hair virgin prior to attempting to color it? And what did you use on your hair exactly and in what order?
