Her hair doesn’t look greasy! It just looks as though the photo’s been glossed over. And I love that classic just-rolled-my-hand-through-my-hair look! (Which is probably what she did!)

she’s pretty when she really smiles

I don’t understand why you keep saying that it looks like she hasn’t washed her hair… Her hair looks great. Just because its unkempt and messy doesn’t mean she didn’t wash it.
I think she looks stunning in ALL of these pictures
