I wanted to thank everyone for their input and continued support for this thread and hope to see continued future support for it!
I've always appreciated the insight of many here and valid questions in regards to which hairstyles and why.

While many players value playable content above all else, there are those of us like myself who see improvements such as hairstyles, housing and the future graphic update to be just as important as playable content.

My guess on the matter as far as why such nice looking hairstyles have yet to grace our presence is simply the focus isn't on hairstyles. (which makes sense all things considered)
And yet, there is a 100% chance Hilda's is in the works but on the XIV teams backburner. They've been known to forget about implementing certain hairstyles (ardashirs ponytail) but have done so recently.
I do ask that in future live letters that allow us to ask questions, everyone who wants certain hairstyles like Hiens, hilda's, Hyth's, Emet's etc to inquire after those.
It's not a waste of time to ask, or a waste of a question imo.
Yoshi-P has in the past said if people wanted Hilda's hair, if the demand was enough it would be added.

(Heck, someone actually asked Yoshi-P if we should save the sandwich that the Exarch had given us back in Shadowbringers and Yoshi-P gave us the honorary face palm. Understandably so lol.)

So, my fellow hairstyle enthusiasts, I ask you continue to persevere and be the squeaky wheel when it comes to implementing hairstyles you want to see.

thank you!
