Yeah, her hair does look light weight to me too. Raking or combing it back while wet styling it is one possibility. Plus what others said: possibly a bobby pin or clip as it dries. There could even be a bit of mousse or hair spray involved.
The only way I can achieve that kind of root lift is to cut it short in front and wet style it away from my face and it still flops into my eyes shortly after which annoys the crap out of me.
Why not experiment to see what works for you?
