The state board may not get involved, but you could try it never hurts to try. The BBB and local reviews may get more attention. I would also tell 10 friends who will tell 10 friends and so on and so on. I have seen more than one stylist in an upscale salon that needed to be knocked down a few notches to reality. The fact that the manager/owner stood behind the stylist is no surprise. I understand you didn't get the cut you wanted which upset you, but it seems you understand that hair is like grass it grows back. You will get the cut you want somewhere else in time. It's the treatment you got that made the worst impression on you and rightfully so. Good luck, glad you got your money back.
PS. I had to go somewhere new to get my hair cut last time as my best friend I went to cosmetology school with that always did my hair passed away from Ovarian Cancer. I had grown my hair out and wanted it cut similar to what you wanted. The girl refused to cut it that short saying I would cry if she cut that much of my hair off. She had to cut 6 inches off of it to do what she did. It looked ok, it was a much longer version of what I wanted. She doesn't know me and that I have been known to go from waist length hair to very short in one chop many times over the years. And being in the business I have seen many clients walk out the door in tears after having their hair cut even though it's what they asked for, so I let it go. I hope to get what I asked for next time.
