Physics Pony Tail Setup

I’m trying to use physics for a character’s pony tail and can’t figure out how to prevent the hair joints from clipping through the the rest of the mesh. I set up the physics capsules for the whole character and it’s working great in the editor (see video below). But in the game the hair doesn’t collide with anything at all and just swings around freely.

Are there any steps I might be missing?
I’ve been having this problem since 4.8 and still couldn’t figure it out, so any help would be appreciated!
