Let me add my welcome! Nice to see another nearly bald head.
You'll quickly get used to the new look. The difference between your current clipper cut and a shaved bald head, looks essentially the same, but the smooth head feels much nicer. You should give it a try.
I thought that the military guys were well known for shaving their heads. Well, perhaps in basic training you don't have time, but after that, go for it. While a shaved head is not exclusively police or military, it certainly fits, and you see lots of guys these days with shaved heads.
Thanks for joining us. Post often.
