Tipping in hair salons (Salon Cu in particular)

[ksushis.livejournal.com]

This Saturday I'm going to get my first haircut in the US (I've been getting them before when I was going home -  across the ocean) and I'm a bit nervous. I'm going to go to Salon Cu following all the recommendations from this community and I was wondering how does the tipping work there. I know that I'm supposed to tip 15-20%, but how do I actually do this? Who do I give the money to and at what point?
Thanks a lot!

Sweaty $1 bills tucked into their underwear.... or was that in strip clubs?
