"Just a trim please."

In the tv series Spartacus, the gayest program on the air, and in such new series as Ben-Hur, many of the young men have buzz cut hair styles. They look great, of course. But I am curious how such cuts were possible in Ancient Rome. I mean they didn't have Wahl stylers like they do today, so how did the local barbers manage to cut every hair so evenly. I guess you just have to accept these things on faith, like the wrinkle-free clothing, smoothly shaven faces, and the fact that everyone in ancient times—except for villains—hard perfectly straight, very white teeth. Well actually, many of today's ancient heros have semi-shaven faces, which also requires an electric shaver.
