A head care system (hair washing apparatus 100) according to the present invention includes a base (bowl 101) having a head support 11 for supporting a head 10 of a human. The system includes a pair of arm units (washing unit 12) for taking care of the head 10. Each of the arm units has a support shaft mounted to the base. The arm units are arranged such that the head support 11 is located between the pair of arm units. The system includes a pair of shaft driving members for driving the arm units in such a manner that each of the arm units rotates about the corresponding support shaft. The system includes a controller 400 for controlling driving operations of the shaft driving members. Each of the arm units includes a contact arm (third arm 107L, 108L, 107R, 108R) having a plurality of contacts equipped on tips of the contact arm, a secondary arm (second arm 106L, 106R) for rotatably supporting the contact arm, and a main arm (first arm 105L, 105R) which rotatably supports the secondary arm and is rotatably supported by the base. The main arm has a four-link mechanism.
