Get a decent haircut for $13. About half of the stylists are have been there for several years - it's random whether you get a good one or not, but once you do find one you like, you can ask for them by name when you come back again. I'd guess there are a good 5-6 that I like, so it's never a problem getting a good simple haircut (I have short guy's hair).
Pros: Inexpensive, Can ask for stylist
Cons: Long waits sometimes, No appointments
