I'm in the category of "my hair looks like crap so I get rid of it"
LOL. This is a great category, and I put myself in it too. My hair is too receded in front and think at the crown and it's all grey and silvery. Plus grey hair has it's own texture! So I just shave it. I got lazy around the holidays and skipped more than a week (OK I admit -- 2 weeks), and I'm seeing why I prefer to be sly.
At times, I do appreciate that stage of growth once the hair starts to feel soft after a couple days of sandpaper. I still kind of like that look. But I agree with Tsuji in that when you do want to sport a super buzzcut it's sometimes best to first shave then skip a couple days. I think buzzing to that length (probably #0000 or #00000 blade), is too much work to maintain. When I buzzed my hair to that length using a balder clipper, I would end up shaving with a razor. I would get paranoid about missing a few hairs and having the cut be uneven. You can't rely on 'feel' with a self buzz as you would with a shave. Easier to shave!
So with 2 weeks growth, I was going to treat myself to a barbershop shave but then I thought about having to wait and pay someone to do work that I can easily do myself. So today, is the day I get myself back on track to being sly.
