Certain men inspire instant hair envy: Bradley Cooper's infamous curly shag in The Hangover, Robert Redford's Ivy League cut in All the President's Men, and Chris Hemsworth's tousled blonde locks that got a boost in the recent Marvel Studios films Thor and The Avengers. Unlike Brad Pitt, Hemsworth – who grew up surfing in Australia – tends to keep his hair tied back in a bun. If you're going to try this look pulled back, try to keep your hair at least chin-length so you have enough to grab on to.
