Hi if i was you i would go and get a colour stripper, but be carefull as you can only strip ur hair up to 3 times.. then once you have done that, it will b ur natural colour, then find a blonde thats going to go with that colour, and not go yellow.. I wouldnt use bleach personally as it breaks ur hair off. As i worked in a salon, and have seen alot of bleached hair recked, you should never put bleach on hair when its gone wrong!
