  In a recent paper (Phys. Dark Univ. {\bf 31}, 100744 (2021)) it has been
obtained new static black hole solutions with primary hairs by the
Gravitational Decoupling. In this work we either study the geodesic motion of
massive and massless particles around those solutions and restrict the values
of the primary hairs by observational data. In particular, we obtain the
effective potential, the innermost stable circular orbits, the marginally
bounded orbit, and the periastron advance for time--like geodesics. In order to
restrict the values taken by the primary hairs we explore their relationship
with the rotation parameter of the Kerr black hole giving the same innermost
stable circular orbit radius and give the numerical values for the supermassive
black holes at Ark 564 and NGC 1365. The photon sphere and the impact parameter
associated to null geodesics are also discussed.
