Sjusta has the option available to give Geralt a haircut, although he claims it is something he does not do very often. Regardless, he can give many different hairstyles that are standard to the game.
He can also be overheard discussing business with a number of NPCs. One example is a warrior in Sjusta's shop talking with Sjusta about a banner he wants him to repair. Sjusta inquires about this in a shocking tone since the banner is one of the Nilfgaardian Empire, to which the warrior explains he acquired it during a raid on some Nilfgaardian forces and he planned to use it as a rug in his home.
