Hair in Andromeda

There's a balance to hair. Everyone knows how to do hair and make it look good. But it's resource intensive. it's why in Tomb Raider, the only person whose hair moves like hair is Lara's  and not anyone elses. If they wanted everyone's hair to sway and move, it'd come at the expense of something else. And seeing as people want photorealistic games, it'd come at the expense of photorealism or poly count or animations or size of environments.

Hair could've moved in the Shep trilogy if they made the hair flat, semi-transparent polygon sheets that everyone would've complained about because that kind of technique is only passible in animanga styled games, and the same kind of technique could've been applied to MEA if they wanted to. And as always, hair would've looked worse.

Hairworks and TressFX are resource intensive; turning them on hampers performance if your setup isn't beefy enough. The payoff isn't worth the effort required. Same reason why clipping exists in a variety of games depending on minor circumstances. Fixing that issue would've been at the cost of something graphical, so they choose not to fix it or choose to let it slide in certain instances in order to hit the graphical payoff since they know people will be more forgiving for minor clipping and hair issues than the game not having 16k textures that detail every crack and scratch and pore on a person's face.
