I've been shaving mine for nearly three weeks now, absolutely love it. It defo me, best decision I've made for ages. Am tied in with a bet to shave everyday for a year anyway, so even if I didn't like it I would be bald for a while longer, luckily I can see me extending my head shave period.
But back to story of my flatmate. After I shaved mine he made a passing comment about how he'd always thought what it would be like. He declined my headrub offer. But a few days later gave in and rubbed my melon. Nothing more was said until a couple of nights ago. He was sat there fiddling with his hair, quite floppy shaggy cut. We weren't up to much, so I offered to shave his head. He had reservations, but I went through the benefits I had found and did the whole "you can always grow it back" and "what have you got to loose" schpiel. Suddenly he agreed and before I know it was sat on a chair in the kitchen waiting!
I shaved him right down to bald, and he loves it. A proper head rubber too. I told him to keep it for 30 days, but I suspect he's another keeper based on last couple of days. Can't wait to see what his girlfriend says!!!!
