The ALICE detector at the LHC is specifically designed to investigate the properties of the hot and dense medium, consisting of deconfined quarks and gluons (QGP), created in high energy heavy-ion collisions. Heavy-flavour particles are wellsuited probes to investigate the properties of such a medium, since they are mainly produced in the initial phase and they subsequently experience the full evolution of the collision. In the ALICE experiment, the Inner Tracking System (ITS) plays an important role for heavy-flavour measurements. Interesting results have been obtained by analyzing pp, p–Pb and Pb–Pb data collected so far. The upgrade of the ITS, combined with the expected increase of LHC luminosity in Pb–Pb collisions, will allow the current performance for heavy flavour measurements to be significantly improved in particular in the low momentum region, and new measurements will become accessible (e.g. the Λc baryon in Pb–Pb collisions). The perspectives for heavy-flavour measurements expected after the second long shut-down (LS2) of LHC will be discussed.
