Why do men go bald on top of their heads but not the facial hair?

There's also studies showing everyone (at least in the study areas) thinks it's goofy unless you shave the sides to match, so that's interesting. Either one of those two facts are wrong, or cavemen were dexterous enough to get the job done with a piece of flint.

As a very bald man, let me assure you, hair does not merely keep growing other places. The exact same hormones make it start coming out of unexpected places like weeds in a sidewalk. So cool. /s

As to why hair follicles work backwards specifically on the very top of genetically predisposed individuals, I can't say. There's a lot of information on the Wikipedia, but probably more to go. I know it's still an active area of medical research. Especially active, even, because it's an old white/asian guy problem (usually).

Don’t make me tap the sign

I'm genuinely curious. By what age did you become bald?

Obsidian razors are one atom thick.

What is there to converse about? Some people seem to confuse asklemmy with Google.

Not the guy you asked but that is a decent question.

My hair thinned massively between ages 21-23, and when I was 24 I’d had enough and finished the rest off with a razor.

21-22 I could get away with it, but by 24 it was ridiculous and nothing could hide it short of always wearing a hat.

No you didn’t.

Yeah, fractured ceramics can be more than sharp enough - really metal is a downgrade at the microscopic level. The trick is that it's pretty hard to get a totally straight edge. The Aztecs did it, but it sounds like it required a mass-produced supply chain of some unknown kind.

I miss a strip on on my non-dominant side every once in a while using power clippers, and we're talking about a wiggly little stone scraper. Primitive people spend all that time we spend on books working with their hands and body instead, and would have a ton of family around so they'd probably never have to do themselves, but it's still kind of impressive.

Well, keep reading. Conversation did ensue. You basically write a summery of the important bits of what would be in the search (reminder Google alternatives exist), and then it's OP's turn to ask follow up questions, make a joke, counter with their own information, share an idea if one occurs to them, or just say thank you.

Androgens, evolution and the the difference between head and body follicles have all been in immediate replies, and then there were spin-off conversations (honestly including this one, although an attempt was made to prevent it).
