A dispenser (20) has a barrel (24; 198), a piston (28) upwardly movable within the barrel from a first position to a second position, and a body (22) of personal care composition at least partially within the barrel between the piston and the barrel top end (44). An actuator is coupled to the piston to shift the piston upward (toward the top end). The actuator comprises a screw member having a threaded first portion (36) engaged to the piston for relative rotation about a first axis (500). The screw has a second portion (50). A cap (60) has a first condition mounted at the barrel top end. The cap has a socket (82) in an outer surface. The cap is removable from the first condition and installable into a second condition. In the cap second condition, the socket receives the screw member second portion to emit a user-induced rotation of the cap about the first axis to, in turn, rotate the first
