How about Cloth Physicks?

[Jeykama]

All I want is for hair to be able to interact with clothing, it seems like it'd be a lot less resource intensive than cloth physics and I can't wear half the chests in the game because my character's hair juts through it, despite being able to be affected by movement and wind just fine.

Sadly hair physics without clipping is REALLY HARD and takes a lot of system resources due to the interaction between hair and body (much less all the different clothing options). Then multiply that by characters on the screen. MMOs (much less ones roped to consoles) aren't designed to require ridiculously top-end systems to display more than a handful of characters at once. Which is one reason why FFXIV 1.0 burned.
