  We show that the no-hair theorem for scalar-tensor theories with bi-metric
structure can be evaded. We find that hairy black hole solutions in the
presence of an electric charge admit AdS, flat or dS asymptotics with
spherical, flat, or hyperbolic base manifolds. Spherically symmetric,
asymptotically flat black holes and asymptotically AdS configurations with any
horizon topology are compatible with a regular scalar field on and outside the
event horizon. The latter presents a rich thermodynamic behavior induced by the
disformal factor that enters as a coupling parameter in the theory. In the
grand canonical ensemble, there is an interplay of stability and first-order
phase transitions between thermal AdS, the hairy black hole, and the
Reissner-Nordstr\"om-AdS black hole, whose thermodynamic phase space resembles
a solid-liquid-gas system, with an electric potential playing the role of
pressure. In close analogy, there is a triple point where the three phases
coexist, being equally probable.
