I guess blondes are consider more rare and that's why they keep adding those in games to give them ''unique" look. Ironically because of that it becomes generic. I come from country were blondes are very common so i would like to see more redheads and brunettes.
@Camel with 2 thumbs to be honest 80s were weird era for everything not only hair. I wish they would have been more faithful to Irene's original design with redesign but meh. Well at least Ryu stayed as brunette.
