Bry and yellow hair?

i have heard all the crappy answers about shampoos. dude they dont work. i went to a salon and got highlights. my hair was once died brown. then i put carmel highlights and i went in for a touchup and then he messed up at the salon and when i went back to him my hair ended up horrible. i have carmel and dark brown. orange and red orange and highlighter yellow colors in my hair. what do i do. i am afraid if i tone it the other colors might get weird?
