To me, it looks like he isn't wearing a hood or hat, but, rather, has a mullet hair"style" and sandy blonde or light brown hair, with nothing covering it. Or, at least, the "business in the front" part of a mullet, since we can't see the back as well. It looks kind of swirled around the crown of his head, if that makes any sense. Like, forward, back, and to the sides, all from the crown, without a distinct part. And kind of a shaggy-ish length (as well as possibly longer in the back). However, I could have just been reading this thread and staring at these pictures for waaaaay too long, creating mullets in my mind where, in fact, it might be impossible to tell what's really there. So, that's just my opinion and what I see.
