We're starting off strong with an actor who is now well-known for having a distinctive bald appearance. However, Willis wore a long blonde haircut for The Jackal back in 1997.
In 1987, Mel Gibson's lengthy beach waves perfectly captured the look of a California surfer. Given that the actor is reprising his part in the Lethal Weapon franchise, which featured a character with long hair, his hairstyle might be related to it.
In the early 1980s, U2's lead singer Bono came into the scene sporting long hair. He changed the style of his hair into a mullet during the decade and then chopped it off for a short punk look.
This isn't Photoshopped, we assure you. Hugh Jackman had a longer, more layered appearance for the X-Men back in 2003. Compared to the short, sleek cut we're used to seeing on him, this is a drastically different picture.
For Legends of the Fall, one of his early movies, Brad Pitt grew his blonde hair long. Before chopping it off, the actor managed to maintain the appearance for a couple more years.
Jared Leto is renowned for his frequent hair changes; most recently, he grew out his hair long and highlighted in waves.
Fortunately for those who didn't like Daniel Radcliffe's shaggy hairstyle in 2014, it wasn't long-lasting. For the sake of the movie Escape from Pretoria, the actor was just growing out his hair.
