Corrected entry: In the early part of Fred Claus, the story teller explains that when you become a saint, you become "eternally ageless." However, when you get to the first scene with Santa Claus, he is complaining about the rest of his hair turning white. If he was eternally ageless, his hair would not still be turning white.

Correction: Just because his hair is turning white does not mean that he is ageing.
He would nonetheless be showing signs of ageing and no longer be appearing as someone who is ageless. Even if the white hair is due to something like stress, white hair is typically associated with getting older or being old. The key to supporting the plot hole lies in the use of the words "eternally ageless." Ageless can mean eternal, but "eternally ageless" suggests he will appear "forever young." If he is ageless, he should never look "older."

And if there is the power of eternal agelessness, there should be an accompanying ability to counteract any possible causes of growing white hair (such as stress, heredity, and dying pigment cells in his hair follicles).
