Clean-shaven men are more likely to harbor infection-causing and antibiotic-resistant bacteria than bearded men.

TOP INSIGHT
Beards may be more bacteria-resistant and hygienic than shaven skin because facial hair does not increase the overall risk of bacterial colonization compared to clean-shaven.
The study also found that men with no beards were 10 percent more likely to have a common bacterium Staphylococcus aureus which causes respiratory and skin infections.
Researchers said that the micro-abrasions caused by shaving may support bacterial colonization and proliferation.
