When I shaved my head, I used a balding clipper followed by the head blade, which I purchased specifically for the occasion. It worked very well.
I wish I looked better with a shaved head. One of the best feelings in the world, but it isn't the best look for me. Looks great from the front, but funky from the side, as I have a weird shaped skull in the back. Still, I'll shave when I start balding, and probably keep it shaved for ever.
I don't shave my entire head, but in warm weather I keep the sides and back shaved.
I use my Norelco electric, after a 000 buzz. Gives me a closer shave, with less irritation than any other method I've tried.
Same boat here -- I used to grow my hair out super long, get sick of it, and buzz it off. The last cycle I noticed I was a little...thinner up top.
I've been using the Gilette Mach3 Sensitive Disposable razors with Nivea Sensitive Shaving gel.
I shave it every day, and usually one of the razors will last me about 6 days before getting too dull. Of course, the trick of stropping on the forearm to keep it a little sharper definitely gives them a bit more life.
I buy it all at Costco, so it ends up averaging about $0.40 a shave, which is pretty dang cheap.
Beard trimmer to get it short, shaving cream and the Mach 3 I've been using on my beard. I have to do it every 2 or 3 days (Hair grows fast) In a pinch, running late or don't have the time I put the rotary on and do a quick pass.
I use the Headblade and Head Slick shaving lotion. Works better than anything else for me.
I've been using a straight razor to shave my head and face for about 6 years now. THough when time is an issue I'll still break out the old gillette 3 bladed rig and just zip it clean in the shower, I love my straight razor shaving.
I shave my head and beard 2-3 times a week. I generally do the head in the shower and use a Schick Hydro 5 razor with just plain old soap. Then when I'm finished with that, I'll dry up and then shave my beard at the sink with the same razor and soap once again. I'll generally get 2-3 weeks out of a Hydro 5 cartridge before I notice it starting to get dull.
