What does it mean when a woman stares at your hair?

So I'm talking to this girl, and she keeps staring at my hair, like when a man looks at a woman's breasts. Is that a "sign"? Hope not, because I don't like her like that (although she is very cool). She does this every day that I talk to her. She also tries to get me to help her out a lot at work. Thanks.
