I honestly haven’t. I have been cutting my own hair for a couple decades now.
I started cutting my own hair about 20 years ago. WalMart clippers and I can get a haircut on a Sunday night at 10 if I want to.
Back in the day, my dad would take me into town every Saturday at 7AM for both of us to get crew cuts. Bunch of old men, many of them vets hanging out drinking coffee and talking about the weather. Late 1960’s.
