I mean think of the logistics of digitally altering his hair. It would have to be done for every frame of every shot he is in. In the behind the scenes photos he isn't wearing a blue or green cap, so chroma-keying his hair would be an absolute nightmare in post-production. I don't think it is just for a promo shot, but I agree it may only be in certain scenes, because otherwise they would have had him wear a blue or green cap, like you said.
