I think most of us do secretly have some facial hair that we shave, bleach, pluck, or use chemicals to remove, especially as we get older. They sell special products specifically to help women hide or get rid of it, as though it were an unsightly blemish. I’ve known a few who didn’t, and they tend to be viewed harshly for it. The hairs on my face are actually the only hairs I remove, aside from the occasional haircut, because it is far more taboo than having hairy legs, armpits, or a bush.
If it were common and socially acceptable, I would grow it out like I do with all of my other body hair. I’m old, though, and I think it might be harder to get younger people onboard. The newer generations grew up with enticing internet videos where everything is shaved except the head, eyebrows, and eyelashes, so their ideas about what is expected, attractive, and normal have been heavily influenced by that. We didn’t have such internet videos back in my day. We didn’t really have the internet, or if it existed, it wasn’t something most of us knew about. We still used typewriters and sent actual hand-written letters by mail, and our phones were attached to our walls and literally had to be dialled by turning a plastic circle to each number, so a lot has changed. One of the things that changed was the ease of influencing cultural perception and spreading ideas. It is much faster now to turn what may begin as a fashion trend into a universal expectation that everyone treats as the new standard. It is possible that this could mean female beards could someday catch on if popularised online, but I see things trending in the opposite direction, where it is far more likely that someday shaving off our eyebrows or shaving our heads will be expected, and anything else will be seen as gross.
