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

[Samantha]

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
