It seems like beards are everywhere you look these days. The popularity of a furry face has risen to new proportions. Regardless of which celebrity is sporting some new scruff, or which fashion models are featuring the facial fuzz, it seems like the beard trend is here to stay.

Beards are also sexy. It’s official! According to a study in the Journal of Evolutionary Biology, which surveyed 8500 women, bearded dudes where much more likely to be considered long-term boyfriend material.

“Beards may be more attractive to women when considering long-term than short-term relationships as they indicate a male’s ability to successfully compete socially with other males for resources,” said one researcher on the study.

So if beards make a man more desirable, what do you do if you’re a guy who can’t grow one? Millions of men around the globe can’t seem to get past the peach fuzz phase, or are plagued with patchy facial fluff instead of the full, glorious beard sported by sexy lumberjacks and wizards a-like.

Scientists suggest there may be a biological reason behind the inability to grow facial hair. The hormonal chemical dihydrotestosterone, or DHT for short, is apparently to blame

DHT is connected with testosterone and is also associated with baldness. However, low DHT does not mean low testosterone.

You could be the most testosterone-fuelled, manly-man, Arnold Schwarzenegger-look-a-like out there, and still have cheeks as smooth as a baby’s bottom.

The trick is that your body needs to be able to convert that testosterone into DHT. A director of Cosmetic and Clinical Research in Dermatology, Joshua Zeichner, told Men’s Health:

“DHT is a modified, more active form of testosterone. In your body, testosterone is transformed into DHT, which exerts stronger effects than testosterone itself.”

This means it depends how your body reacts to DHT. If you don’t have much of it and you aren’t particularly sensitive to the DHT you’ve got, then a bushy beard is a no go.
