When to came to the hair transplant group, the men were rated as 3.6 years younger after they had the hair-restoring procedure.
The same group were also judged significantly higher for attractiveness, approachability and level of success.
In an article in the journal Jama Facial Plastic Surgery, the researchers wrote, "Men were perceived as being younger and more attractive by casual observers after undergoing a hair transplant.
"Participants also rated post-transplant faces as appearing more successful and approachable relative to their pre-transplant counterparts.'
"These aspects have been shown to play a substantial role in both workplace and social success."
Previous studies have also suggested that men who experience hair loss at a young age are less fertile than their thicker-haired counterparts.
However, it's not all bad for baldies. According to research from the University of Pennsylvania, having a shaved head makes adult men appear taller and stronger.
And there may even be health benefits to going bald.
Researchers from the University of Washington found that men who started balding at a young age were less likely to develop prostate cancer later in life.
