I have very blonde hair and never dyed it before, I dip dyed it with blue kook aide just for fun, I really liked it the first few weeks now its starting to fade and it's a real ugly greenish blue and I want it out, how can I?

It can be very hard to get out. I suggest reading some of the many posts where this question has already been asked and answered, and maybe try some of the things people have suggested. If none of them work go see a hair care professional. And please people, stop putting this stuff in your hair! :)
