Whether or not men look sexier with or without facial hair is one of the age old questions women seem to have a debate about.

Every woman has a differing view on whether or not men look sexy with facial hair, but a new study has found that the majority of women are currently less impressed with bearded men.

Researchers from the University of South Wales showed 1,453 heterosexual and bisexual women and 213 heterosexual men photos of 36 men, both clean-shaven and with varying amounts of facial stubble and asked them to rate how attractive the men were.

Because beards have become more popular in recent years (with the influx of hipsters and phenomenoms as 'No-shave November'), they are more common, which the study finds contributes to the lack of beards being sexy these days. Because truly clean-shaven faces are more rare, the study finds that those faces are being seen as more attractive.

"When beards were rare, hirsute faces were more attractive than when beards were common ..." the authors said. "Conversely, when clean-shaven faces were rare, clean-shaven faces and light stubble enjoyed their greatest attractiveness, and beards became less attractive."

Beard fever has found its way into Hollywood as well, and considering the study's findings, it's interesting to see how some of the most attractive men in Hollywood rank among women based on their look-with or without facial hair.

Enstars compiled a list of 10 of the most attractive actors in Hollywood and put together photos of them both with and without facial hair. Be sure to scroll through the photo gallery and take our poll -- who in Hollywood is sexier with facial hair than they are without?
