Does how much hair a man has matter in how he is perceived? A gigantic cosmetic surgery industry say it's true. What we unclear was how much was objectively true versus how much it was just a confidence-builder. If a man was self-conscious about being bald, he may seem more insecure. With hair, that might go away. Does that make him seem more attractive, though? 

A new paper in JAMA Facial Plastic Surgery claims they are more attractive - at least on surveys.

Lisa E. Ishii, M.D., M.H.S., of Johns Hopkins University School of Medicine, Baltimore, and coauthors suggests men with androgenetic alopecia (pattern baldness) who underwent hair transplant were rated by observers as more youthful, attractive, successful and approachable. All those factors can play a role in workplace and social success.  

The authors surveyed 122 people (about 48 percent of whom were men) and participants were asked to rate 13 pairs of images. Seven men in the pictures had hair transplant and six men who did not have hair restoration served as controls for comparison.

Limitations of the study include its small population and study design.

"These findings are relevant in building an evidence-based body of literature surrounding the efficacy of hair transplant in the treatment of AGA [androgenetic alopecia]," the authors conclude.
