I died my hair brown 5 months ago before I died it I was light blonde.. Is there anyway on this earth that I can get my blonde back ?

Unfortunately no not unless you bleach the brown out of your hair! And if you did that I suggest that you go to a professional the bleach will damage your hair! Or another thing you can try is all over highlights to tone down the blond if you don't want to bleach it all!

I agree with lovebug, I am also blond and our hair takes color differently, to reverse the color see a professional they can work to remove the color from the dyed hair and not disturb the new growth.

You could go to a hair dressers salon and see if they can do anything about it. Next time do wash out
