A hair roller includes a tubular body having a generally cylindrical outer wall and defining a hollow chamber therewithin, first and second generally circular end closures respectively sealing first and second longitudinal ends of the tubular body to prevent air flow therethrough, and an annular adapter. The outer wall has a first hole and a plurality of vent openings formed therethrough. The first hole is configured to receivably engage a first open end of the adapter. A second open end of the adapter is configured to interconnect with a first end of a conduit such that, upon the first hole receivably engaging the first open end of the adapter, the adapter facilitates a flow of air being delivered from the conduit through the outer wall into the hollow chamber via the first hole and out of the hollow chamber through the outer wall via the vent openings.
