Jon Hamm, 39, will soon battle for a Golden Globe statue for his work on Mad Men, but off camera, the star is fighting a more common battle - hairline recession.
From recent photos, it appears that Jon is Norwood Class II, which means that while his hairline is maturing, typical of an adult hairline, he has yet to see any frontal balding. He is also fortunate to have an otherwise full head of hair.
This type of recession isn't uncommon for men Hamm's age. In fact, 40 percent of men in their 40s experience hair loss. However, he might want to consider a proactive hair regimen of FDA-approved Rogaine or Propecia to help stop further recession.
