I gotta receding hairline, and the only prescription is more cowbell!

Actually, Christopher Walken's hair loss prescription is no less ridiculous than a cowbell—he pulls on his hair everyday to keep from losing hair!  Does this work?

Absolutely not.  In fact, doctors recommend staying away from hairstyles that pull your hair because the added stress can actually cause you to lose hair.  Just imagine what forcibly pulling on your hair could do!  Walken says that he emulates President Kennedy, who he claims used to do the same thing, which is why he had such great hair.

The best gauge for whether or not the hair-pulling method works is to look at Walken's hairline:  it hasn't seen his forehead for at least two decades. 

There's a name for the condition that urges people to pull their hair, it's called trichotillomania.  Considering that pulling his hair is part of his daily regimen, we'd like to at least consider the fact that he's a borderline sufferer of the disease.
