You have to understand what to expect:
1. Your hair will be cut by a student. It could be their first haircut ever, or they could be about to graduate.
2. Your haircut or color will be inspected by an instructor at the conclusion of the service. They usually will take a few snips here and there if the student missed anything. There are only a few instructors, so you may be waiting.
3. It will take much longer than at a real salon.
What else would you expect? They are students.
The prices for services are much cheaper than nice salons that use Aveda products (which are awesome).
Knowing these facts, I think you can have a good experience here.
I don't go here for color. I don't want to risk that with a student. I periodically go here for a cut though and would recommend any guy that normally uses a Great Clips (or discount place) to give it a try.
