Andromeda runs on the same engine as Inquisition.
Supposedly, making hair is freaking hard for video games, and it just so happens that making hair with Inquisition's engine (Frostbite 3) isn't the expection. If that's true, then Andromeda's hair selection / variations should be just about as low and bad as they are in Inquisition. Sorry to burst any potential bubbles around (I wish I was wrong, I just normally expect the worst case scenarios now from AAA games).
On a side note, there are a couple of exceptions around. Two come in mind right now, namely The Witcher 3 (then again, what is that game not doing well?) and the 2013's Tomb Raider reboot. But those two games run on their own " in-house " engine (Witcher 3 runs on REDengine 3, and Tomb Raider on Crystal Dynamic's own Foundation engine). I suppose that good hair quality AND variety (I.E. crap load of hair style choices during character creation) in Andromeda would only depend on two things: 1) if BioWare learns how to, or figures out a way to do it with Frostbite 3, or 2) They stop development on Andromeda, create their own engine, master its intricacies, then restart development of the game. That really just leaves us with one way to go doesn't it.
Seriously though... it's a question of time and budget, I think. I'm about 95% convinced that Frostbite 3 is a perfectly-capable engine for rendering / portraying hair properly, but the devs themselves sort of... you know... have to do it. If the guys working on the hair styles are content with 10 for males and 10 for females (some of which would be identical anyway for both genders) and call it a night, then there's really not much we can do about it (regardless of the engine, too).
