Does Chris Hemsworth's hair grow incredibly quickly, or does he just have a way of wearing extensions that make them look totally natural? We only ask because he seems to have a different length of hair every time we see him.
Hemsworth has spent much of the past few years playing 'Thor' in the Marvel movie series, and as the character has long hair, it would make sense for him to keep his grown out. Between films, though, it seems that he trims it off and then grows it back miraculously fast.
