Well, I have a soft spot for men with neat, long hair... But the colour is his decision. He looks gorgeous with black hair, in interaction with his eyes... But I like him with curls too. The only thing he should keep the hands off is the beard!
I'm torn. I pag-ibig Loki's hair, don't get me wrong. But Tom's natural curls are absolutely sexy and adorable too. I miss his curls :( But I also think that I would miss his black hair if he never dyed it again.
i just loved how his hair was in thor. it made him look like a true asgardian royal. on the other hand his hair in the avengers made him seem truely powerful and menacing. the black in his hair is just too sexxy
