Hair goes through multiple phases.
It’ll grow for a while, then fall out. Even beard/head hair. It just has a longer grow phase before falling out.
Which is why short hair grows an inch way faster than long hair does.
How does it know it’s short?
The follicle pooping it out is basically only gonna poop out so much before it poops out.
TIL Hair = skin excrement
Have you ever seen someone’s arm after they have a cast taken off? Your arm hair is short because it’s being rubbed off by random interactions with things (rubbing against shirts you take off/put on, your body, general use). A person with a cast on their arm protects those hairs, and when they finally get the cast off, they look like a werewolf.
It’s not a satisfying answer, but your DNA tells it.
Short hair doesn’t grow faster. It’s a myth.
It’s weird how often I get comments from people days later, who think they know what they’re talking about about, but are missing a piece that explains it.
If you’re going to comment on old threads, try asking a question. I probably would have explained for you and you could have learned something.
That was 3 hours later, not really old besides he’s correct: hair doesn’t grow differently because of it’s lenght but because of it’s placement on the body.
Mate, you don’t know how time works, let alone hair…
I don’t think I’ll be missing anything if I don’t see either of your comments again.
Good luck
Dude, what are you on? Stop being an asshat
So I have a follow up question, let’s say someone has 20cm long hair, all of them are that long, we don’t see 5/10cm hair still growing to get to 20, I’m confused, how does that work?
You don’t see them because the longer hair covers them up.
They’re still there.
If it happened to big patches at once it would stand out, but that’s not how it works.
Yeah it makes sense
A better question would be, “when does hair know when to fall off?”
Hair never stops growing.
Edit: when I say “hair,” I mean one single strand of hair. That single strand of hair will eventually fall off. The thing is that not all strands fall off at the same time. So hair, the full head of hair, seems to be of the same length (especially if we keep getting haircuts.) But it’s not like all hairs grow and then all of them collectively say “ok, everyone, let’s stop growing!” and stop. No, each single strand of hair falls off, but at different times.
No, hair does stop growing.
Hair grows in phases and cycles. At the end of the cycle, it falls out.
The difference between body hair and the hair on your head is that the latter one has cycles measuring years, the other weeks.
This is the correct answer. Here’s a little graphic on the phases.
No, hair does stop growing.
Hair grows in phases and cycles. At the end of the cycle, it falls out.
This is unhelpfully pedantic given the OP’s misconception.
Hair does not (appear to) stop getting longer because it stops growing. It (appears to) stop getting longer because older (longer) hairs fall out.
What’s „unhelpfully pedantic“ about a correct answer that explains OPs misconception? 🤡
The person above said hair doesn’t stop growing. That’s wrong. It does. It grows, then it stops growing, then the dead hair falls out. Why does it know when to fall out? Because it’s dead, Jim.
OPs question was why the hair on their head grows longer. Answer: because it’s growing cycles are longer.
I’d say you’re unhelpfully pedantic telling other people giving helpful and correct explanations they’re „unhelpfully pedantic“.
I’d say you’re extremely unhelpful because you give an „explanation“ that’s just complete bullshit and doesn’t explain anything.
I don’t think we’re disagreeing. That’s exactly what I meant. But I can see how my wording could have been misinterpreted, so I’ll edit it.
