Captain Caveman is the most scientifically accurate depiction of homo sapiens in their natural state. If we never cut our hair or shave, our hair and beards would grow down to cover our whole bodies.

Secondary shower thought, an image of Captain Caveman should be the image representing humans on the Wikipedia page.
Tertiary shower thought, we probably started wearing clothes because our own hair used to be our clothes, and we wanted to replace the hair we cut off when we started grooming.
IIRC some hairs have maximum length limit and some will keep growing, generally based on position on body. Eye-lashes and most body hair being of the former, while skull and beard hair being of the latter.
You can see pictures online of people who've let their head or beard hair grow for years, and the results can be pretty amazing. Ditto finger nails.

It's not that hair knows it's length and stops growing until you cut it, there is no mechanism for it to register its own length. Rather, there is a natural rate at which hairs will break or fall out and begin to grow again, and so a person's hair can only get so long before the longest hairs are due to be culled.
This isn't entirely accurate. The length limit doesn't check if they reached it. Hairs are dead tissue. Instead it is the amount it grows by before falling out.
Nails tend to not fall out but experience Abrasion from use.
Technically, it goes down roughly to your thighs. I was being hyperbolic for humorous effect. But Captain Caveman is probably closer than most depictions of prehistoric man. David Letterman has a longer beard than any of the artistic depictions I've seen of a human in their natural state.
I learned that from The Cowsills, LOL
... I haven't cut* my hair in over a decade, and it's been more or less the same length for the past 3-4 years. After a certain point your hair falls out regardless of cutting, and for most people that's around 7 years.
EDIT: Forgot to include the actual length, which is core to the point. It's about waist-length for me, but some people's hair does get longer.
What makes you think that people haven't been cutting their hair since forever? Our ancestors who came before homo-sapien had cutting tools. Hair can also be burned by the fire they could also make. I'd imagine hairstyles are older than humanity.
I get "angry" (I don't know, some emotion forces me to take action) when there is a hair in my field of view.
I'm guessing if vision is so important for modeling the world that they'd die without it, they'd do something about it (bind / cut / burn)?

Re: tertiary shower thought: I think that was a theory for intelligence development, but also because less grooming.
Hair is a nice place for parasites to live in. That's why monkeys spend so much time grooming. If we're too lazy to groom, we evolve to not have hair, so the parasites don't have a hairy nest to snuggle up in. Then we evolve the big smart because it's cold out and now you need a jacket.
Although peoples hair has a max length that is dependent on the person and the situation. That is why people growing out hair need to have dead ends cut off so that it will grow more. I would not be surprised if like the zz top guys had to so something similar to get that length.
Cutting dead ends doesn’t promote growth, but it prevents the hair from getting shorter. Split ends (being finer) are weaker and more liable to break, tangle, get caught in a brush, etc. Cutting them off stops the split from getting longer.

A "Showerthought" is a simple term used to describe the thoughts that pop into your head while you're doing everyday things like taking a shower, driving, or just daydreaming. The most popular seem to be lighthearted clever little truths, hidden in daily life.
Here are some examples to inspire your own showerthoughts:
If you made it this far, showerthoughts is accepting new mods. This community is generally tame so its not a lot of work, but having a few more mods would help reports get addressed a little sooner.
Whats it like to be a mod? Reports just show up as messages in your Lemmy inbox, and if a different mod has already addressed the report, the message goes away and you never worry about it.

Not so. Your hair and nails have a built-in, genetically predetermined, maximum length. Once they reach that length, they'll stop growing.
For most people, they'll never get anywhere near the limit. But it's there; your hair won't continue to grow and grow like Rapunzel.
