I started with the summer buzz cuts in my early teens mainly because my, then thick long hair, got in my face while swimming, was incredibly hot and sweaty and of course buzz cuts looked cool in old movies.
Through the years I tried a lot of hairstyles, long, short, mohican, beaded, braided.... you name it. But to be frank, the freedom and confidence (it's a choice) a hair free head gives is the best.
Sure my hair line started to reseed and the stuff on top thinned out, but as others started to grow what was left longer I returned to what I've done before. Using the clipper on and off for 10-12 years, usually skipping the winters, since they can be brutal in Sweden but always going short in the summer, I finally for about 7-8 years ago got in the shower with a razor. There's no looking back from that.
I just moved on to electric as you can read about here,

Have a smooth head!
