Touching up roots by highlighting

I need some help.  I have been highlighting my hair for years now ( my natural color is brown).  I had my roots touched up yesterday @ a professional hair salon.  The only problem is my hair turned out a reddish-light brown color with a few strands of blonde.  The problem is I wanted it to be blonder than it is.  I think the problem is the hairstylist left the toner on too long which toned the color down too much.  My question is is there any way I can fix this myself without having to drive an hour to have the salon redo it?  Any suggestions would be AWESOME.  Thanks!!

Thanks a bunch, Karen!!!
