I know, another celebrity hair transplant thread...just what you wanted, right? Hey, until we get a cure this is what we're stuck with.

The above photo compares Welker at 2005 vs 2011 before he had his infamous transplant. Looking at his forelock in 2005, which appears to be mostly gone, and contrasting it with his forelock in 2011, it appears he may have already had work done.

Recent photo showing his hair after his transplant in July 2012. Looks pretty good, especially in comparison to 2005.
