Compact astrophysical objects, like black holes and neutron stars, are going to open a new and enlightening window on gravity in the forthcoming years. The study of such objects in strong curvature regimes will a priori allow to test alternative gravity theories, like scalar-tensor models. I will discuss spherically symmetric and static objects in the framework of Horndeski theory, proving the absence of scalar hair for most models. I will also carefully classify the possible ways to escape this no-hair theorem.
