Hi, welcome.
All very interesting about the head shaving thing. I have been using a straight for almost a year, with a DE on Saturdays and a shave almost every day. I shaved my head (first time ever) I think about two weeks ago. I decided not to continue shaving it for completely stupid reasons (one being the SWMBO.....Well, I guess that's a little unfair, she's only partly stupid), but felt at the time that shaving it with a straight would really be pretty hard...
