If my regular hair guy is in, it's actually really cheap since he's the newest to the salon (but still awesome) and it's about $25 with tip, but about $35 if I have to go to someone else when he's out of town. If I get it colored as well, it's usually about $70 total.
I'm amazed how much price difference there is between cities as far as hair cuts go, depending on how "hip" or whatever the city is. Pittsburgh is not so hip, so even though I go to a pretty swanky place to get my hair done, my brother goes to a similarly swanky place in San Francisco, and his hair cut is $100.
