I'm really surprised that your hair dresser didn't tell you about blue shampoo, you just use it like any other shampoo (lather and rinse- you can even leave it in for a minute or so but its not recommended because it can cause your hair to turn blue if left in too long) but the blue tones down the brassiness. I've used it and it works great. brands I'd recommended are Rusk (which also sells blue condition) and if your looking for a cheaper option shimmer lights. you can find either in any salon, ask for help once you get there and they can explain it in more depth.
