BioWare has always been terrible with hair. I had hoped the new hardware and engine would allow them to improve, but I expect it. Sadly, we got more crappy, recycled hairstyles. They really are so bad as to break immersion. Such work will not be good enough for the next ME, I hope they realize.
I was looking forward, at least, to having black hair. Sadly, they made the same mistakes with hair color that they made with ME and ME2. I play those on 360, and I can't play a created Shep without editing Vectors and Scalars to make things look more natural. (The same is true of ME3, though not specifically with black hair, which actually looked okay on that game.) Playing now on PS4, I have no idea if and when save editing will be an option. I haven't even looked into it.
I know I am tired of my BioWare characters wearing plastic helmet-hair. You guys write great characters, but you really need to step up your game, in this regard. It's embarrassing, and it ruins verisimilitude for some of us.
