Other opinion here: Women really find hair attractive, and without it you will have harder time dating. Lot of bald man compensate this somehow (career,gym, etc.).
Assuming that's true... well, if you're just looking to meet random women for hookups and flings, sure, ok. But I don't think I'd want to be in a relationship with someone who wouldn't date me because I shave my head bald.
You slightly moved the goalpost here: I said women find hair attractive. That is not the same as saying women will not enter a relationship. I know this is a hot take and unpopular, but women historically have most of the time (and still do it today - albeit probably not to the same amount) entered relationships with men they don't find attractive.
My situation improved significantly the moment I got rid of it all. Perhaps some of that was down to a boost in self confidence, but the look suits some people far more than it does others. I wouldn't go back if there were a cure.
Confidence is not a replacement for hair, it is a requirement in the first place
My favorite term I heard from female friends is "cap-fishing" - meaning a man places a photo wearing a cap (to conceal baldness) on his first photo in a dating app.
