What's the psychology behind the person who changes hair style often?

I know a girl who changes her hair very often.
Every her facebook profile photo has different hair style. Also, i've only met her 3 weeks ago but she has changed her hair style twice already. Why does she do that? Is it her obsession? or could she be a perfectionist?

My guess is that shes in the Witness Protection Program.

If its only the way she styles her hair there's no actual issue there. She probably just likes to try new things and doesn't want to look the same all the time. It's like a girl changing clothes, no biggie. If she's cutting it or dying it drastically often then maybe it could mean she's not into commitment if your searching for a physiological reason. But most likely she just likes to switch it up now and then which doesn't make her obsessive or a perfectionist
