Hair Question

So I’m watching a few videos on UE4 Hair, and saw a pretty good one for Blender. But I see a lot of people using strips or a head cap with polystrips. My question is how do I attach hair to the model when it’s a separate mesh / best method? And can I do it with MasterPoseComponent? Like how I see people doing for switchable clothing / armor, is that something workable or is that too demanding long term?

And is there a vid out there for this? I see a lot of ways to make hair, but not really one on how to get the hair attached.
