OK so yknow how you can modify your face and body now right? There should be a “modify” button when you choose a hair too with options like hair density, length, and hair type (like curly, wavy, etc). OR just a hair labeled “Mod Hair” or something that you can do all the other stuff BUT also change the direction of the hair, by moving it around with your hand or something.
This would enable people to “express themselves” as RR likes to call it more PLUS people can have unique hairstyles and maybe creators can even have signature hair!
PS: also a modify button for facial hair.
