I have a beard, but I trim it frequently, about once a week. Do the pubic area every time I bathe or shower. I never cut my hair (traditional Taoist), but I get the ends trimmed every once in awhile. I keep it tucked into a ponytail or braid most of the time, because if I wear my hair down I look like a crazy nerdy barbarian.
Actually, I guess I look a lot like my avatar, just less grey...and with glasses. 8D
