Atm I personally would use Apex for realistic hair movement 
-> it works the same as it is shown in those videos:
?v=NGfqR3yAfAc
?v=Vp-2owf695Q
So you just have to add a bone - do the apex part (so tell apex where and how far something should move) - export it
Another way is to animate it with a rigg -> so every animation has his own hair movement.
