Here's some good news for all the guys participating in No-Shave November, everyday with facial hair makes you more attractive.

The "Journal of Evolutionary Biology" found that men with facial hair are most attractive than men who are clean shaven. The survey had 8,500 women rate men on how attractive they are.

The results showed that men with heavy stubble, like ten days worth, are the most attractive. After that are men full beards and light stubble, with clean shaven men being last.

The researchers believe that there's an evolutionary aspect to the attraction, also beards make men look more masculine. "Beards may be more attractive, as they indicate a male's ability to successfully compete socially with other males for resources."
