Query: New no-scalar-hair theorem for black-holes   A new no-hair theorem is formulated which rules out a very large class of
non-minimally coupled finite scalar dressing of an asymptotically flat, static,
and spherically symmetric black-hole. The proof is very simple and based in a
covariant method for generating solutions for non-minimally coupled scalar
fields starting from the minimally coupled case. Such method generalizes the
Bekenstein method for conformal coupling and other recent ones. We also discuss
the role of the finiteness assumption for the scalar field.
