Haircut?

I've had long hair for a number of years now. I last cut it all off with a samurai sword and have let it grow back to at least shoulder length. Anyway, 31 now and the pressure on my hairline from a ponytail means I'm at risk of going bald. I'm trying to be a bit more sensible these days so time for a change and I'm going to abandon my hippy look for a traditional short back and sides. Sad to see it go but the hairdresser is here now and I'll use the old hair for a nest for my hamsters.
