Let's give the photographer credit. This is from Ethan Beckler.

Really highlights how it’s rough and gets everywhere

Doesn't look like any other micro image of hair I've ever seen. In all the other pics i can find online hair looks a lot rougher than that. Maybe it's a synthetic hair?

Interesting how so up close both objects seem transparent. (I know, glass is basically sand, but still)

Looks like glass noodle mmm

They must have used frame stacking to get everything into focus like this, I imagine...
