I'm lucky, I've a good head of hair, (thanks dad & the rest of the ancestors) but after the first Covid lockdown it did look ridiculous with quite long hair, despite the odd trim from the wife.
First chance I got I was in the barbers & asked "The usual?". For some reason I found myself saying "No. Give me a number 1. That first cut, right down the middle of my head, forehead to the nape of my neck & I nearly freaked out, wondering what I'd done, how my wife would react?
But I remember leaving the barbers & walking out into a lovely sunny morning with a gentle breeze blowing round my head & it felt great.
I've kept it the same way since with a haircut every 3 months now. A lot less messing about.
