In a Swiss study conducted in 2018, scientists compared the bacterial loads of 18 bearded men between the ages of 18 and 76 and 30 dogs of various breeds. Swabs were taken from beard hair below the men’s mouths, while dogs were swabbed in the “particularly unhygienic” area on their necks between their collarbones where skin infections are most common for pups. Results showed that while only 23 dogs showed high microbial counts, all 18 of the bearded men were found to be laden with bacteria. The researchers also discovered that disease-causing bacteria showed up more frequently on the beards, writing that “the beards of men harbor significantly more microbes than the neck fur of dogs and these microbes were significantly more pathogenic to humans.” They concluded: “On the basis of these findings, dogs can be considered as ‘clean’ compared with bearded men.” And for more on what not to wash so often, see why you should Stop Washing This Every Time You Shower, Doctors Say The obvious answer to a germy beard is to make sure you’re cleaning it.

Stevie Warwicker, the store manager of a London branch of the barbershop chain Ruffians, told The Guardian that the exfoliation can help you avoid problems such as beard dandruff and “will help to get all the loose skin and rejuvenate,” especially if you have a longer beard. He says that two to three times a week will do the trick. And for more health and hygiene news delivered right to your inbox, sign up for our daily newsletter.
When asked whether or not brushing your beard can help keep it clean, Warwicker jokingly replied: “It depends what they’ve eaten.” But using products like beard oil or styling products and running some bristles through it can be the most effective way to shape it and keep it looking great. “It wouldn’t necessarily help for hygiene purposes, but for styling purposes it would definitely help,” Warwicker told The Guardian.
