I rock the marine-do.... shave my face with a 1/2 guard, and my head with a 1 guard, do it myself. Do the side-burn and over ear lines myself with no guard, and every second cut I make my wife straighten out the line on the back of my head with no guard.

Honestly, 2.5 years ago, right before my wedding I went to a haircut place to get my hair cut for the special occasion. There were single strands everywhere that were missed. I ended up touching it up myself, if you buzz you head, you have to go over it in 6-8 directions to make sure you don't miss any stragglers. Apparently the "professional" didn't know this. I decided I would never pay to get it done again.

Also, if you buzz it that short, there is zero need for shampoo, at 1/4" long, there are no split ends or brittle hairs. I just wash my whole body, head and all with Irish spring. More savings!!
