5. He Looks Insta-Masculine
Sounds like a cliche, but there's legitimate research behind this: a study published in Evolution and Human Behavior proved that the more facial hair a man has, the more masculine both men and women perceive him to be. So if you're into the burly, testosterone-driven type, he should skip the razor for 10 days — that's the exact length of time the study found that women find men the most attractive.
6. He's Trendy
Maybe it's because of bushy-faced hunks like Ben Affleck and George Clooney. Maybe it's because of the growing popularity of No Shave November. Maybe it's because that scruffy hipster look is so "in" right now. Either way, bearded guys are on the rise. More and more men are checking in with their doctors to grow thicker beards, taking multivitamins and even prescribed medication that stimulates the male hormone dihydrotestosterone. Amazon.co.uk found that sales of beard trimmers have grown by 47 percent this year, too. Think of all the men you can date!
7. He Scares Away The Bad Guys
There's a reason why bearded men are born warriors. A study published last year in Behavioral Ecology found that bearded men appear more intimidating to other men. The researchers think a beard makes a man's jawline look bigger, which can make him seem more aggressive when he's angry. You know he's a big softie on the inside, so you know there's no reason to fear the beard. You can walk down the street holding his hand on a dark night in confidence.
