My hairstyle really hasn't changed in the last 55+ years.
Two exceptions.
Looking at elementary school photos, age 5 to about 7 I had a number 2 hair cut. Probably because money was tight and I didn't need as many haircuts that way.
And I went from March 2020 to November 2020 during the start of the pandemic without a haircut. Barber shops were still closed so my wife and daughter bought a home hair clipper set and cut my hair. Longest my hair has ever been. There is at least one guy I worked with that still haven't gotten a hair cut since the pandemic started two years ago. Yes, he has a pony tail now.
