Huelan's not upset that Eva is fixing her hair. This is a selfie, with the phone set up so that she can see herself as she's snapping pics. This girl practices these faces in the mirror, or really, any relfective surface- sliding glass door, car widows, glass case at the supermarket.
Sometimes she put her hands on her hips.
It's not always a furrowed look, either. She has Surprised, Pleading, and my favorite, Coy (complete with averted eyes and rapid blinking).
