Just to talk about anything not political.....
I haven't been to a barber in 30 or more years.
I kept it regulation short in the military (not boot camp short/bald). And the base barbers were good at regulation, quick and cheap (and they knew my name and were friends). I tipped more than the haircut cost ($2.50).
When I got out, I let it grow just a little longer, but was already balding at 40. I went to a few local barbers and they cost a lot more and you often had to wait a while, so I just got some decent clippers and did it myself. For a long time I buzzed it down short, but looking like a felonious wanted poster, I went back to a short brush cut.
There's just a hint of color in my head hair, but my face hair (goatee) is pure white. I am never outdoors without a 3-color desert tan boonie hat (except at night), because the sun is not my friend (skin cancer).
I only need to do it every few months when I start to get fuzzy. The back is where most of my hair is, and it has to be done by feel. I just did it again, and only took one chunk out behind one ear. Screw it, it's good enough for government work.

And while there's not much hair, I do it outside; hang a hand mirror on my bike shed door so the mess is not in the house.
What do you guys do?
