I have her hair, unintentionally. It's working pretty well for me, but you have to be prepared to wash and blowdry every morning to get the style. There's no way your hair will stay like hers for over a day.
If you do get it, and you find one morning you wake up with no time to do your hair, do this:
Get a small barreled curling iron, curl the ends of your hair out in a flick. Back comb top at the back to create some volume, and run a bit of wax through it. It's a quick fix that doesn't look amazing, but will look better than the 'I just woke up and my hair is as flat as a pancake' look.
