Hollow Ichigo and Tensa Zangetsu fused before Ichigo used the FGT. When Ichigo lost his Shinigami powers, he lost his Hollow powers as well as they were one and the same at that point. He then regained his lost Shinigami powers through a device Urahara created meant to restore his Shinigami powers, not his Hollow powers. Considering that we have seen no trace of Hollow powers from him since (and no, you can't say Fullbring as how Ichigo could use Fullbring is still a mystery), it is very likely Hollow Ichigo is just dead. And to that, I say good riddance.
