What Does Hair Taste Like?

No, seriously? The title isn't meant to be cryptic or anything like that, I am just curious. Everyone freaks out when they get hair in their mouths, so I am curious if anyone can tell me what hair tastes like. Does it taste like shampoo? Does it taste like Rocky's fur smells? I don't know if I have ever stopped to consider it. Thanks in advance for any help you can contribute to this mystery!
