Robert Pattinson may not be known for his Method acting -- but he's definitely got Method hair. I'm telling you, that hair is so mercurial. One day, it's Robert Pattinson, the next it's Robert Redford, and then Robert De Niro. Honestly, I don't know who that hair is most days. I'm not sure Rob does either. Rob has more hairstyles than most women do. This is a man who thinks nothing of going long and lustrous and then turning around and chopping it all off. I won't say his hair is bipolar, because that totally got Kylie Jenner in trouble. Let's just say it's moody. Here are 8 of RPattz's most interesting hairstyles.
