I think some of you are giving the OP a bit of a hard time for something not very complicated at all. While I wouldn't be opposed to more "African" features, I know they won't ever make it here because Yoshida said the character creator won't be updated any time soon. So we can lay that to rest. The lack of any kinky hairstyles is noticable and I think asking for more after this many years is a perfectly valid request.
We can start with making the Elezen female Fade cut, Midlander Frohawk, and Dreadlocks on female characters for all races and genders. There is no reason why men can't have locks. There is no reason why only Elezen women can cut their hair. There is no reason why only Midlanders can have a Frohawk when every race can have an Afro. Do away with these weird restrictions first and foremost, it would go a long way into making black-looking characters. Once that's dealt with what's the harm in adding more tightly twisted braids, cornrows, or a more shaggy haircut with kinky hair to the sea of straight hair we get in every single patch? Seriously. I get that 80% of the game is "white" but hey, it's difficult to make a "black" character so that could be why you don't see them as much.
Also, and most curiously, there ARE black people in Eorzea, plenty of them. I'm not sure why so many are saying or implying that they aren't in the game. I don't know what you guys are looking at. There are many black and "decidedly black" NPCs in game already. Sawney, that Gold Saucer guy with the gambler outfit, a completely random Skinchange GATE female NPC, many many NPCs in Gyr Abania which I'm guessing is where they come from, and I feel pretty certain that Raubahn is a black guy. Or "decidedly black". I'm not just talking about dark characters either because I know the "tan" excuse. I'm talking about the daarrk Hyur NPCs. The game lacks customization so it doesn't show it very well, it's no different than people from Othard(Asians clearly) looking straight up white. Devs had no issues adding Asian hairstyles though <.<.
In the end, I think people should lighten up a bit about this as there are no lore reasons against black people existing(they already do) and Yoshi still adds hairstyles. Give it a chance instead of trying to say it's political or that "we don't need it because this isn't Earth". Kugane obviously isn't Japanese. Those aren't Japanese people! Silly me. Ala Mhigo certainly isn't Middle Eastern. And Ishgard CERTAINLY isn't European. Give me a break.. let's not be sooo technical.
And lastly as a black person myself, I'd love to see more hairstyles compatible with a black character design opened up.
