A study by UNT researchers reveals that men's loyalty to grooming products is influenced by how satisfied and invested they are in their appearance.

In the study, Jessica Strübel, assistant professor of merchandising and digital retailing, and Trent Petrie, professor of psychology, surveyed more than 700 men and found that those who were satisfied with their facial features and invested in their appearance were more likely to be committed to a specific brand of grooming products. Men's sexuality also plays a role, as the research shows that gay men are more likely than heterosexual men to be dissatisfied with their appearance.
