It does not have necessarily something to do with her "Education and Carreer" but with her individuation as an adult person: But in younger years she wore her hair hanging to the right side of the face, while as an adult to the left side.
Interesting, since the left side of the face is associated with emotions. Sine her hair hangs now there, this side became smaller - what means, she is more self controlled now after university.
Well, kitchen psychology - I am loving it ...
