Yeah, the upkeep is a PITA tbf. That's the one reason I'm growing mine a smidgen longer. I have to get it cut really frequently or else the back grows out faster than the side and looks dreadful.
But if it wasn't for that and I would keep it.
I probably feel the same as you do op, being told to cut your hair, when people say "short hair is so ageing, like you've really let yourself go", (only on here obviously, because anyone who saw my amazing hair would never say that
).
I think long hair looks not all that nice on more people than you'd think. I do think, God how do they stand that? Not "they look ugly" or anything, but more like "why? Isn't that a total PITA"?
It's different if you really suit it, or even if you don't care, but just love it. But, what I don't get is women of all ages being invested in their long hair as if they're a 10 yo who can't bear to have their rapunzel hair cut. I basically don't think as many people really suit long hair as think they do and I find it
when grown women get precious about it, like "oh no, not my beautiful mane. I couldn't possibly have it cut, I'm still a pwincess" 😂.
It's fine to have whatever hair length you like, but when people say, "you can't have SHORT hair
. It just isn't conventional, male gaze version of attractive", I do think "sad twat". The OP's mum's "style rules for the over 40s" are definitely outdated though. It's about what genuinely suits you. I just happen to think fewer people genuinely suit long, long hair than think they do. That goes for all ages.
