I've never had my hair colored or processed at a salon before, only box due several years ago which I have since chopped off. I want get my hair lightened, I'm currently level 2 and I want level 4/5. I'm in the Ny metro area (willing to drive down to Jersey for this), how much should I expect for this? Also, how can I tell the hair stylist knows what they are doing? Sorry my friends don't know anyone to recommend so I have no clue on this matter.
