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.
Sjusta is a tailor and can 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.
