Looking at the images on the top, I've noticed that there are some hairstyles and bang types that aren't in the game. Are those new, or scrapped?
of the ones on the front page, all of them are currently obtainable in game - use any mirror in a bathroom to re-style your hair, though it limits you to specific styles for swimming, sport and home outfits I think. there are some unavailable hair styles on NPCs. Also, you might just be looking at them with th wrong perspective, or they might be displayed differently in certain cutscenes.
