As well as having the coolest name and voice in Hollywood, Vin Diesel has the best head. Delve into your imagination to picture him deliver his glorious brand of laid-back asswhooping with a long and luscious Harry Styles type barnet. It wouldn't work.
The action star's shiny scalp also gives him greater aerodynamic abilities, as shown by his gravity (and plausibility) defying leap across several motorway lanes to catch Michelle Rodriguez mid-air in Fast & Furious Six. He'd have barely managed to reach two feet off the ground with an afro.
