Particle hair won't obey the rig.

[Solowren]

So, my issue seems like it must be easy to solve, but I can’t figure it out. I’ve used Rigify to add a rig to my character, and I’ve gotten everything all worked out and it works just fine, except for one thing: None of the hair particles will follow the rig. The emitters themselves will follow, no problem, but the hair just kind of… floats there. All detached.

Anyone know how to fix my problem?

So it turns out, for my particle hair to deform properly, the armature modifier needs to come before the particle modifier.
