In this short article, prepared for the proceedings of the Corfu Meeting 2016, I review three aspects of skyrmion/baryon black hole hair which have been investigated recently [1, 2] and which I presented in my talk in Corfu. First, I will argue that one can detect the classical skyrmion/baryon hair which, as it is well-known , a small enough black hole can carry in classical scattering experiments of waves. Second, I will show that, under certain assumptions which I will point out, a black hole can not only carry the known classical skyrmion/baryon hair but also a quantum skyrmion/baryon hair which can be detected in Aharonov-Bohm type experiments in which a probe string encloses the black hole. In contrast to the known classical skyrmion/baryon hair, the Aharonov-Bohm type quantum skyrmion/baryon hair can be carried by black holes of arbitrary size. Third, I will argue that from the point of view of a low-energy observer who can measure the Aharonov-Bohm type skyrmion/baryon hair of a black hole, black holes respect Skyrme topological charge/baryon number.
