IDK why the OP decided to list "Curly/Wavy/
Messy/Afro" and then reiterate that twice more (like, wtf are you even saying? Trying to equate these textures with being "messy"? Cause, there are "messy" hairstyles in this game when you look at the "Anime protag bed head" styles like Saintly and Early to Rise ... so wtf you mean?) but I'm not gonna bother trying to unpack w/e "that" is.
Anyway, Black and would love to have Black hair options. I think Highlanders are the best looking females in this game body wise, but the fact that they don't get the 1 okish looking black hairstyle that's race locked to middies AND their lack of black facial features makes them turn out looking like brown PoC instead of black. More black hair would def do a lot to fix this. (I mean, going by what the murals and Concept Art show, I'm 100% going for Hrothgal when they come and hoping they have shared hairs, so I've prob never gonna try Highlander again. But either way, playing a Viera or Hrothgal that can have good-looking black/ cury hair would be great!)
Being realistic, the only way I see it happening is via the old hairstyle contest. Over the years, the devs have only made non-hair contest hairstyles as either fan service (the NEIR raid hairs/ stuff from other FF games like Windcaller or cutter or w/e) or to give people long straight hair cause done of the winners were long hairstyles.
The hairstyle contest had a grand total 3 black hairstyles (The Femroe braids aren't REALLY black but "it'll work")
Given the rate at which they release hair, and the fact that they've only recently started doing non-winners ... we could see them in the next big patch or "not even in 7.0" :/
EDIT- IDK what the person above me is talking about, but Elezen females can be bald. They are the only females who can be bald as it's a racial hairstyle .... not many Elezen Females, and I've never seen 1 use that style, so I guess that may be why most wouldn't know that..
