Breaking news, guys: eight out of the top ten sexiest men alive have beards. Do you?

The world is celebrating a resurgence – of facial hair. On Glamour's 100 Sexiest Men 2017 list, eight of the top ten guys are at various stages of bearded-ness. Though the smouldering billionaire Christian Grey in the movie Fifty Shades of Grey and its recent sequel Fifty Shades Darker is clean-shaven on screen, the real-life Jamie Dornan, who topped this year's list, has a healthy set of whiskers.

Of course, there are various styling considerations when it comes to growing a beard. Check out a few of the sexy gentlemen from the top of the list – and the popular styles they've been sporting:

Also called the Hollywoodian, this vintage look connects a moustache and a goatee, and extends up the jawline. Jamie switches between this style and the full beard, but he had to shave it bare for Fifty Shades of Grey.

The traditional full beard is a face that's chock full of connected whiskers. It's also considered the most manly style of beard – if it's well groomed.

Named for Italo Balbo, Mussolini's right-hand man in the lead-up to the Second World War, this style combines a moustache with hair on the chin and a "soul patch" under the lower lip. It's also been sported by Robert Downey Jr in recent years.
