The Roan pattern would normally not just be about the head as your pretty girls is. This was my Sable Roan girl just before she birthed her litter. Note how she has the roan ticking throughout her head and body .

Most often when the band gene combines with the Roan gene it results in a roan headed hamster with a white body starting at the neck and goning all the way back to the tail. The band turns all the sable roan coat to white so the whole body ends up white.
