With No Shave November in progress, men and women have grown out their hair to spread cancer awareness and donating the money used for shaving and grooming to cancer prevention.

The iconic song lyric by Miley Cyrus, “I can’t be tamed,” applies to men’s facial hair as their clean-shaven faces progressively become bountiful beards.

And it is beautiful.

Not only is No Shave November for a good cause, but it has also been proven to make men look increasingly more attractive.

According to a 2013 Australian research study (released in April 2014), women prefer men with heavy stubble and full beards.

Disclaimer: it depends on the environment.

If the majority is clean-shaven, then women rated the men with heavy stubble and full beards significantly more attractive. But if the majority would be men with facial hair, the turnout would be the opposite.

However, when women preferred facial hair on a man over clean-shaven, it was by a large margin.

But why is it so? What is it about that scruff that women seem to love? Does the facial hair subconsciously ignite a woman’s primal instincts?

According to Prof. Rob Brooks, the evolutionary factor driving this result is the simple fact that “beards tend to make those men who can grow them look more masculine.”

Here’s the science behind this: during puberty, the ability to grow facial hair kicks in, transitioning from a kid to a “man.” The prominence of facial hair on a man visually shows a woman that yes, he is a man. And based on the thickness and perhaps even style of the beard, it shows just how masculine that man is.

This trend of facial hair has started becoming popular within the past few years. Hipsters started this aesthetically pleasing trend and so far it has been a success.

Personally, I 100 percent support this fashion statement. I find beards sensible and attractive.

It’s basically winter; beards keep your face warm. It’s like mittens for your face.

Moreover, beards give guys that rugged, just-finished-cutting-wood look. And if that doesn’t get most girls hot and bothered, nothing will.

Last, it’s No Shave November. Nothing is more attractive than doing something for an important cause.

For all you bearded men out there, keep growing that facial hair and look beautiful while doing it.
