Not only did Jon Bon Jovi have long hair in the past, but he continued to wear it long for a very long time past the point where anyone thought it was cool or fashionable to do so. His dedication to keeping the style alive is to be admired.
With the tight curls and the almost-mullet style of presentation, it's obvious that this picture was taken in the 1980s, but Bon Jovi was still rocking it way into the 1990s. His screaming fans never seemed to mind!
