Head shaving is quite in vogue here in the US, and I imagine probably so in the UK too. I don't think it ever completely went out of style since the days of Yul Brenner. It has recently had a champion in the iconic Michael Jordan, and is a common sight here in the US.
Frankly, I think some people look better with a shaved head than with hair - like Sean Connery. I personally can't do it because my head is shaped so strangely that I'd look like something out of Star Trek.
