> One thing we learned during COVID was a significant limitation in people's willingness to stay isolated was their hair was getting out of control. It's the exact, boring, unsexy topic that you omit if you're selling the fantasy of survival and you include if you want to cover the boring, day to day logistics.

COVID wasn't really a survival situation though, and least not in the traditional sense (i.e. staying at home for long periods ordering stuff of Amazon).

In an actual survival situation, I'd suppose you hack away at your hair with a pair of scissors or a knife, because you're dirty and starving and have more important things to worry about.
