I've been cutting my own hair since 1995, which was the last time someone else cut it. Shortly after that I remember walking past a barber's shop and seeing a sign that read 'Cheapest haircut in London - £5' and thinking "piss off, that's 3 pints!". My hair grows unevenly, quite fast, and is reasonably thick, so even when I was paying to get it cut I'd have to trim it myself after a couple of weeks. The key for me is to cut little and often. It's harder to make a mess of it if I'm only cutting off small bits at a time. Also I don't cut my hair when it's wet, because the strands dry back to different lengths so if my hair looks even wet it'll look uneven once it's dry.

I trim bare clippers every week and every few weeks disposable wet razor to the skin
