It wouldn't destroy the story line. It's called a plot twist...
As far as hair falling out from dying it. I'm sure that being hit by a giant fire ball would kill you, but Naruto's still alive. I'm also sure that being hit in the chest with a ball of lightning would kill you, but Gaara's still alive. And I'm 100% positive that you can't pull your spine out of the back of your neck and not die, but hey, Kimimaro did it!
Basically, real world logic or rules don't apply to the world of Naruto, no point in trying to use them.
