Smyrna Bangs can be achieved from curling your bangs, spraying with hairspray, then teasing your bangs with a comb or pick and spraying with hair spray again. The higher and stiffer you can get them the better.
She must use a whole can of Aqua Net to get those Smyrna Bangs so stiff and high. I bet a tornado couldn't mess those Smyrna Bangs up.
