  We build on the observation by Hawking, Perry and Strominger that a global
black hole space-time supports a large number of soft hair degrees of freedom
to shed new light on the firewall argument by Almheiri, Marolf, Polchinski, and
Sully. We propose that the soft hair Goldstone mode is encoded in a classical
transition function that connects the asymptotic and near horizon region. The
entropy carried by the soft hair is part of the black hole entropy and encoded
in the outside geometry. We argue that the infalling observer automatically
measures the classical value of the soft mode before reaching the horizon and
that this measurement implements a code subspace projection that enables the
reconstruction of interior operators. We use the soft hair dynamics to
introduce an observer dependent notion of the firewall and show that for an
infalling observer it recedes inwards into the black hole interior: the
observer never encounters a firewall before reaching the singularity. Our
results indicate that the HPS black hole soft hair plays an essential role in
dissolving the AMPS firewall.
