I spent a solid ten minutes staring at this today. The thick, dark, structural steel rebar you see on top? That’s from my nose. The pathetic, translucent strand of spider silk underneath? That’s from the top of my head.
I actually looked up the science behind this because I felt personally attacked by my own biology. Turns out, nose hairs are genetically built to be "coarse air filters," so they grow a massive, rigid inner core to trap dust. Meanwhile, scalp hair is just meant to be "flexible insulation."
But the absolute worst part? The same hormone (DHT) that makes your head hair shrink, thin out, and eventually pack its bags and leave, is the EXACT SAME HORMONE that tells your nose, ear, and back hair to mutate into indestructible wire brushes as you get older.
So no, my head hair will never be as thick and luscious as my nose hair. My nostrils are out here building a maximum-security fortress, while my scalp is slowly giving up on life.
TL;DR: If anyone needs me, I'll be looking into scalp transplants using nose hair donors.
