I don't really know of any (except to say stay away from the Supercuts on Montgomery and Tramway-how one mangles a simple boys crew cut is beyond me, but they managed) however you might want to try the cosmetology school. I have a friend who gets all her beauty care done at one (sorry, different state) and she has always been happy. The instructors don't let the students do anything without making sure it is correct (re: color, etc-the scissors I think you might just have to risk, lol). I've never done it, but back when I was in college I got all my dental work done at the dental school for free, and they always did a good job. Some theory.
Here is a list of prices:
Find and Contact an Olympian University Cosmetology School in your area for the training you need for your career in Cosmetology or Aesthetics*
If it is in pretty poor shape now, at those prices, I'd give it a try. They may not turn you into Jennifer Anniston, but it will probably be better than self care at home.
If you try it, let us know how it goes.
