Pretty much exactly this, yes. Rose brought him back to life while temporarily possessing the entire power of the TARDIS' Time Vortex. Unfortunately, she didn't have the experience needed to use the power wisely - so she effectively froze his body at the moment just before the Daleks killed him. He can't grow his hair, he can't grow a beard, and he can't sustain any serious injury - much less die. I'm postulating that this is how he remained sane after being buried for centuries by Gray - his brain can't be traumatized any more.
