Working away from home, I had gotten into the habit of cutting my own hair, which alleviated the above issues, however upon returning home my significant other, when I bring up the idea of shaving my head again, tells me "But you look so handsome with hair!" When I was away from home I went to a barber once and then got to thinking..."Hey, I can save a few bucks shaving my own head!"
For those that decide to do this, a few pointers...
Lesson 1:
Don't use an under powered battery powered beard trimmer. They stall out!
Lesson 2.
Make sure you have spare batteries if you havn't learned lesson 1 yet.
Lesson 3.
A hand mirror is critical to have...A digital camera will show the spots you missed but it is a pain. The reflective side of a CD only shows so much! Not so much for the top, front and sides, but for the back.
Lesson 4.
Buy a hair trimmer. They're not expensive and they plug into the wall. No need for batteries.
Lesson 5.
Find a barber that you're comfortable going to, and stick with them!
