It was recently shown that gravity theories that couple a dynamical scalar field to the Gauss-Bonnet invariant can lead to spontaneous scalarization of black holes, allowing these objects to grow "scalar hair" once certain conditions are met and to remain "bald" otherwise. While most works on the topic have focused on isolated black holes, progress has recently been made in understanding this effect in binary black hole systems. I will give an overview of what has been achieved so far in this context. I will discuss new phenomena that happen in black-hole binaries and explore some of the potential observational consequences of these results in gravitational-wave astronomy.
