Nicole Richie's hair preweightloss and success?

Did anyone ever see these her on Simple Lifeand think WTF is she doing with her hair, for all the $$ that they claim to have, why can you tell that their hair is fake?? I didn't but I know ppl are like that as that's what happened to my friend...I know ppl talked **** about Cami from Laguna Beach...Do you think people are mean to them in real life and do think it's out of jealousy ?
