Everyone's bald lol

So, none of the hairstyles work for me for some reason. My friends say that the hair works for them, i tried reinstalling the game twice, deleting cache and WTF but it still doesn't work for me. Does anyone know how to fix this? Everyone looks weird lol

It's the new wotlk client with WoD models. You can either continue using it and deal with the visual bugs or use the old version instead.
