What is with hannah gosselin's lllooooonnnnnnggggg hair? why is is so much longer than the other girls'?

i mean i don't really like that show. kate is a nit picking snob. and she doesn't even take care of her kids. i know that their aunt jodie said on her blog that she is not allowed to be on the show because the show offered her a little money and kate and john said no we are the only ones who get the money. and kate has nanny's and she only cooks and runs errands when they are filming. but what is the deal with hannah's long hair? why is it so long?
