He would simply have been taken aback and a little, well ... weirded out, but he was a Weasley, and it wasn't as though no one had ever started in on him for being a ginger. "I don't charm my hair," he said, with obvious disapproval. It was probably stupid to feel defensive at the suggestion that he looked to be the sort of person who might charm his hair, but ... well, really. Was that what she had been trying to do, in the middle of Diagon Alley? Did people do that? "And you really shouldn't either, until you get inside." What if she had hit him, after all? It was hard to imagine being stuck with blond, or something.
