What makes girls so obsessed with their hair?

i love my hair but I'm not obsessed with it, I love people playing with it and stuff.some girls hate it but I love it :)

We can't walk outside with our hair all puffy looking like if we was fighting with the blow dryer.

A girls hair is who she is. Long hair makes her feel sexy. Short hair makes her feel cute. If her hair is messy (tangled messy not gel and mousse messy) she probably is very lazy.

It's one thing we have complete control over. We can make it any length, any color, and with the technology now, any texture. Girls like to have control over things.
