Back "in my day" there was no term "buzz" for close barber sheared hair. Just the "crew cut." Many young boys got crew cuts during the summer months for comfort.
I never had good hair...always looked liked crap with no body. Finally, in my 40s, I sheared it off with clippers with no comb on it. I got nothing but positive feedback and never looked back. Since then, the only change I make is changing the adjustment lever on the side of the shears up or down...making a very minor change in length. I used to buzz" my facial beard on the lowest setting and my head with the lever down...so there was bit of distinction between hair length on my face and head.
Recently, the beard is down to a moustache and the head is sheared close. I'm even thinking about shaving it.
