That assumes that money has anything to do with why she's on The Amazing Race.It is all about building up the ego in the face of extreme lack of self esteem.
I think her equation is:
1. Being on TV gives me self worth
2. Must be pretty if I am going to try to grab extra camera time.
3. Only attribute that makes me pretty is my hair.
4. Cannot try to get more camera time if I'm not pretty.
5. Less TV time per episode means I'm less worthy.
It is sad to see how completely insecure she is.
