Wil consistently wears her hair in a tightly pulled back ponytail, but shortly after her mother moves in she goes to visit her grandfather wearing an army T shirt. While she's adjusting the TV antenna, her hair is uncharacteristically puffed up with no explanation. All scenes before and after show her hair in the tight ponytail. Quite a bit later, there is a scene where Wil's mom sends her to the beauty shop to find out gossip. It's there that Wil is wearing the same army T shirt and getting her hair rolled up in big curls - the end result of which would be puffed hair!
