How to get my yellow hair platinum blonde?

I DYED MY DARK BROWN HAIR BLONDE AND IT TURNED YELLOW WHAT DO I DO TO GET IT PLATINUM BLONDE??

go get it bleached at a hair salon professionally... my best friend did that like 5 times literally and couldn't do it... if you have dark hair its impossible to turn it platinum blonde by using blonde hair dye... go to a salon and either buy bleach or get it done..

bleach it
