Groom Hair Flying! 4.27

Okay, so I’ve been working on Groom Hair styles for a short while now and so far I’m liking most of the results. One result I don’t like is when the bangs of a certain hairstyle kind of fly and flop upward when moving the character forward. When running, it looks okay but it only real occurs when walking, similar to a sort of bubble or balloon inflating. Anyone else get that and know how to fix?
