I'm getting my hair professionally cut this thursday for the first time in about ten years. (I've been trimming it myself in between)

And frankly, I'm nervous.

I have an appointment with a guy I know to be good with hair in general, but I have no idea how he cuts curly hair. (I don't think I have a lot of options on this one, I live in the middle of nowhere, midwest USA) It's the best salon in town, and I'm spending a small fortune on this cut... Any recommendations on how to handle it when I go in?
