Haha, okay, I'm sorry for offending all your shiny heads No, seriously, I don't have anything against a shiny head, but I don't really like it on myself. It's like some pieces of clothing or accessories: it looks awesome when I see it on other people, but just weird when I'm wearing it myself (e.g. a turtleneck sweater)
Once you shave smooth for a while, you get used to the awesome feeling of a smooth, slick scalp. It feels great to run a hand over the shaved skin. For both reasons, it's hard to go back to having hair, even buzzed down!
The funny thing is that the difference only matters to us - the SBG crowd. To most people, if I get a #2 buzz or less, they say "you shaved your head"...But when it's our own head, and the feeling is as important as the look, there's a huge difference between a buzz and a razor shave.
