In New Moon Jake cuts his hair short because it's और convenient(Sp?) that way because when he shifts into a भेड़िया his hair would be longer if he had long hair so he cuts it short. And ya i think it looks better that way too.
in new moon, but i cant recall if there was a conversation about him growing it back in the अगला book because he thinks bella likes it longer? eh cant remember, gotta re read it again lol
I think he looks super HOT when he cuts his hair. In Eclipse I read that he was trying to grow it a bit longer because he thought Bella prefered it like that but she told him she liked it both ways.
