  This is a brief summary of the most important hairy black hole solutions in
3+1 spacetime dimensions discovered over the last 25 years. These were first of
all the Einstein-Yang-Mills black holes and their various generalizations
including the Higgs field, the dilaton and the curvature corrections, and also
the Skyrme black holes. More recently, these were black holes supporting a
scalar field violating the energy conditions or non-minimally coupled to
gravity, and also spinning black holes with massive complex scalar hair.
Finally, these were black holes with massive graviton hair.
