Looking at hair_between_eyes -bangs, it seems like most of them qualify for the bangs tag, although I don't want to create an implication, since I can think of instances where bangs wouldn't apply, e.g. a tight ponytail or pigtail where a single lock of hair extends between the eyes.
Can someone check me on my understanding of bangs? I'd like some input before I do any manual tag adding.
