  We consider quantum gravitational corrections to the Oppenheimer-Snyder
metric describing time-dependent dust ball collapse. The interior metric also
describes Friedmann-Lemaitre-Robertson-Walker cosmology and our results are
interpreted in that context. The exterior corrections are an example of quantum
hair, and are shown to persist throughout the collapse. Our results show the
quantum hair survives throughout the horizon formation and that the internal
state of the resulting black hole is accessible to outside observers.
