Right, I have brown hair, and asked for lighter brown highlights today when I went to the salon. Yet I have ended up with blonde highlights, which do not match my natural color underneath, and it looks extremely streaky.. any ideas on what I can do to either get my natural color back or tone the highlights down, and I can't go back to the salon as there a close family friend, thank you :/

I would recommend going to a professional and letting them know your situation. Do Not attempt to fix this yourself as using more product may have unwanted results.

--- Why do you feel that telling your close family friend that the highlights need to be toned down is a bad thing? They should be able to take criticism and learn from the mistake. Almost certain that you are not the first one to have that reaction.
