Ari's hair has grown and been fixed since the hair thing so this is fake.
Plus she only still wears the ponytail because it's what she's most comfortable with but you can still catch her with her hair down from time to time so bye.
I feel like with her new era she'll have her hair down more. It's something to keep people talking. Like how Justin Bieber changed his hair and everyone had an opinion. Her manager is Scooter too, yes?
