When I moved to the area three years ago I was having a hard time finding a good colorist. The problem was that most salons use Redken color because it's cheap and my highlights and color never came out pale yellow blond and looked more brassy with Redken. My sister is a hairdresser (in NJ) and told be to find a salon that uses Swarzkopf color because it's a superior brand.
I would recommend Essence Salon in Dundee. They are very reasonable. I have shoulder length hair and a touch up cost me $35. When I got highlights I chose the cap method because of time constraint (you also have a choice of foils at Essence but it cost more) and with a toner it cost $85.
Good luck.
