Predicting Baldness Patterns | Pros and Cons of Hair Transplants | Hair Growth Treatments: Do They Work?

Hair loss in men can be devastating to self-esteem, confidence, and body image. Consequently, hair replacement is a huge industry. However, hair loss can also be a sign of a medical problem.

Significant baldness strikes about 50% of men aged 50 years. By age 70, about 80% of men have the characteristic monk hairline—bald on top with hair only around the temples and back of head.

"Men fear baldness so much because it's a sign of the aging process—that he's getting older and becoming more vulnerable," says William Boss, MD, associate chief of plastic surgery at Hackensack Medical Center. "It's natural for males to think they are invincible, but baldness is a very visible chink in the armor."

Oddly, a completely shaven head—like that of Mr. Clean, Yul Brynner as the King of Siam, and Sean Connery—can be the picture of manly virility. For most men, the dreaded loss of hair starts with a receding hairline and, with time, results in hair that covers only the back of the neck and just over the ears. If balding starts in the teen years, it is usually extensive. Some balding men only call attention to their condition by growing the hair above their ears very long and then combing the scant strands across their glistening domes. Others just wear hairpieces.
