Maybe they'll make a Black Emporium type thing sometime after launch that will have more hairstyle options, since I'm still certain Bioware did intend for the qunari to have more hair options
I will pray to the Maker every night for this to be the reality that's in store for us...
But I doubt we will be getting more hairstyles until DA:I 2... Bioware has never released a DLC with new hair, have they? I can see them adding a Black Emporium (only because that was a HUGE oversight to not include it from the get go...!) but I think we're stuck with shitty hair this time around

Otherwise you'd think Mike Laidlaw or someone would be like "don't worry guys! Pretty hair is on the way!" instead of shoving a Twix bar in his mouth and mumbling about how those four ugly things are the only hair "styles" we get.
