Wait, I thought hair was made of keratin like nails. It's made of cells?

Are you implying that your fingernails were never cells of your body? How does that work?

Well I'll have to look it up now, but I see it as a substance produced by the body that isn't made of cells itself. Like any of the other excretions and things the body makes.

Edit: apparently both your nails and hair are mostly made of keratin, but keratin isn't produced and excreted to produce the nail and hair structures like a playdough factory like I imagined. Special cells are produced that are primarily keratin and they are added to like a chain and die/harden as they are pushed out from the body.

Damn, well that is interesting

[-] keegomatic@lemmy.world 3 points 3 weeks ago

That is absolutely fascinating. I had the same assumption.

I'd guess both are made of cells with lots of keratin in them, though i am making this up as i go.

Rule 1: All post titles except for meta posts should be just plain "hmmm" and nothing else, no emotes, no capitalisation, no extending it to "hmmmm" etc.

I will introduce more rules later and when I finish doing that I will make an announcement post about that.

For overall temporary guide check out the rules here: https://www.reddit.com/r/hmmm/wiki/rules/

I won't be moving all of them here but I will keep most of them.
