I went to a hair salon to have my hair colored a light brown, and they colored it red, bright red. I am naturally a dark blonde and I have highlights. Well, I tried to color it myself and it has left a bluish purple tint to some of my hair. Is there any way to fix this myself??

Honestly, I don't think you are going to be able to fix this yourself.

You are just adding more color onto more color... the results are probably not going to come out how you wish.

Your best bet is to go back to a salon and get it fixed.
