I just got in done Friday and when I left it was a very pretty strawberry blond w blond highlights... now its orange and yellow all brassy it looks horrible what should I do? I was thinking a/b trying the tone correcting purple shampoo or should I just go over it with an ash blonde?
Ask them about it - a lot of places will correct jobs if it's gone wrong. As long as they didn't give you direct care instructions which you avoided they should be happy enough to offer you some sort of solution.
At least try that before some DIY repair job which could make it worse in the end.
