Understand

The "no hair" theorem is not applicable to black holes formed from collapse of a rotating neutron star.

Rotating neutron stars can self-produce particles via vacuum breakdown forming a highly conducting plasma magnetosphere such that magnetic field lines are effectively "frozen-in" the star both before and during collapse.
In the limit of no resistivity, this introduces a topological constraint which prohibits the magnetic field from sliding off the newly-formed event horizon.
As a result, during collapse of a neutron star into a black hole, the latter conserves the number of magnetic flux tubes N_B = e \Phi_\infty /(\pi c \hbar), where \Phi_\infty is the initial magnetic flux through the hemispheres of the progenitor and out to infinity.
