If you are a guy, heads up green hills definitely meets your needs, if you are a girl, don't expect a salon type atmosphere, Heads Up is closer to a Great Clips than a salon. However, for guys haircuts Kim does an awesome job and I would highly recommend her.
Heads up has this weird policy where a walk-in hair cut costs x, but if you walk in and ask for a certain person or make an appointment they charge you an extra $2.00. After having a few of the people there butcher the crap out of my hair, I know find it worth the $2.00 to ask for Kim and make sure it's done right. Also make sure to ask for a towel around your neck, otherwise they'll use that scratchy tissue paper which is uncomfortable and doesn't keep any hair off your neck.
