There's also the Wild West Barber shop from Mapps here at the RMP.

I've also had a request in for one at Poserworld, but haven't asked about it recently. Steve seems a bit overwhelmed/overworked of late. Lots of requests. I used the above barber chairs and made my own when I needed one, taking bits and pieces from other sets. Took forever to find brushes and combs. Never did find an electric hair cutter.

Nothing like an old fashioned barbershop.
