I don't mind the blond hair when it's really blond--Paul looks like a completely different person, but it's not a bad look. But those in-between shades, when his hair is a kind of reddish blondish brown, generally don't work on him.

My favorite hairstyle is when he had it all in braids, like in the "going to heaven" pictures; my least favorite is his long greasy hair ca. Dead and Alive. I do find the Tintin hair surprisingly cute, though.
