I shaved it the first time with just clippers. Then over the weekend used my mach 3, but that wasn't a new blade. Today I got my headblade and the headblade shaving cream stuff.
I was amazed at how little time it took. When I was in the Marines many years ago, a few of us shaved each others heads a few times. All we had was the disposable razors and it took over an hour to do, and my head was all sliced to pieces. Today I had maybe 1 or 2 nicks and was done in 10 minutes. It got it super close though.
I haven't gotten the moisturizing stuff from headblade yet, so just used some lubriderm. It feels ok, but makes my head shiny. I ordered the matte stuff since I really don't want a shiny head. I do like the over all result though. I don't see myself as shaving every day but maybe a few times a week.
