Erosion is largely done by sediment being transported by the water I believe. The same principle is used in cutting water jets, it isnt the water pressure that cuts things, the water is a medium for abrasive materials
I think water by itself can randomly break a few loosely bound atoms off the surface of anything. But the rate of that dissolution is dwarfed by the wear effects of the sediment being transported by the water, which is the primary material remover.
So… why don’t those abrasive materials destroy the hair in the drain?? Explain yourself
Just give it a few thousand years.
Given enough time, same water would carve the tiles around the drain.
The hair though, that remains.
Envisioning a pretty nasty post-apocalypse sci-fi movie here… Title ideas? ‘The Hair That Remains’ ‘Hair For Eternity’ etc

Hair is pretty tough, just see how easily it dulls steel blades
This genuinely just improved my outlook on buying new blades
It’ll make its way through. Just give it a few thousand years
I guess it’s because of the water force. Water tend to has stronger force in nature place than in a pipe.
The millions of years helps too
New rock paper scissors just dropped. Rock Water Hair.
Hair blocks water. Rock breaks hair. Water cuts rock.
because how much force the water is hitting it matters, you can just cut your drainage pipe in half if you use those water blades.
