It doesn't add anything new to the game, but makes hairstyles available for more races. For example the elf ones for Tieflings and Shadowhearts for all races and so on. I don#t want to mod the game too heavily because EA and patches, but I figured, that this one doesn't change too much and so far it works fine. It works with the Steam version and pc.
