Plus 1 for diversity across faces and hair for Asian, Indian, Africans and people of Arabian descent
Hair styles for people of African descent is more obvious, but the others?
It's the same as Caucasians outside of some niche styles like Geisha hair or very oldschool traditional braids men used to wear.
If you want to get into that stuff then I mean there's a lot from Europe too that aren't in the game either, I can think of a lot from Scandinavia alone.
I think we might be taking it a bit far at that point tho xD, even if I think it'd be cool.
Edit: With that said, I went in and looked again and there really are quite a lot all things considered in the game already.
Not saying that they shouldn't add more, I'd like to see more all-around especially with straight bangs.
But I mean even as it is now I think that there are quite a lot of hairstyles fit for characters of African descent when you consider that it's just one out of many ethnicities.
