We don't know for sure yet, but given the "style is everything" vibe that CDPR is pushing then I can't really imagine that cosmetic surgery and whatnot isn't going to be a thing.
On one hand, it screams in the face of what we'd consider a "proper merc" in 2020 to dress up like a peacock on steroids, but the game is set in 2077, the world is looking very different, and V "looking the part" of however their story unfolds would be sort of expected in a deep RPG.
And frankly, in a world where ripperdocs can just replace your arms and put various skeletal upgrades into your spine and replace your eyes and nothing bad happens... In that world I find it incredibly hard to imagine that you can't get a darn haircut or dermal enhancement or what have you.
But as always, we will see.
