Here is a conclusion of an interesting study that has a particular relevance to me:
"The Chronicle of Higher Education reports on a study in the Journal of Marketing Communications, which found that among bearded and clean-shaven men, the bearded men were generally deemed more credible.
The study showed participants pictures of men endorsing certain products. In some photos, the men were clean-shaven. In others, the same men had beards. Participants thought the men with beards had greater expertise and were significantly more trustworthy when they were endorsing products like cell phones and toothpaste."
