I get it cut about once every two months or so. Whenever it gets a bit too messy. My girlfriend has been cutting my hair for me recently which is good because she does a good job and I also avoid small talk with hairdressers which I usually find tedious. Though it often means her mum and sisters are the ones offering their opinion rather than me...

Shaving tends to be every other day with my electric shaver. I find shaving tedious and annoying - a constant losing battle with my own facial hair.
