I gradually got tighter and tighter buzzcuts until I got down to a #1. I went to the barber for the buzz every two weeks. It looked pretty good to me throughout that two week period, but if I got a chance to look at the back I realized that the bald spot at the back of my head got more and more emphasized as the two weeks progressed.
I kept the #1 buzz for several months, maybe even a year; but then when I was on a vacation I started shaving the dome. I got comfortable with shaving and the look before getting back to my "normal world." I knew as soon as I shaved that I would never go back to the buzz.
Hardly anyone said anything when I returned because I had been wearing the #1 buzz for so long already. Those who did say something, praised the decision to go bald.
