agent comprises a pair of holding parts (1, 1); each having heating block
(2), the surface of which acts as a holding surface (7); at least one
holding part (1) containing liquid container (5), liquid holder (4) that
brings the liquid in liquid container (5) in contact with heating block
(2) as the liquid in liquid container (5) is transferred to heating block
(2), and steam path (19) that sprays from holding surface (7) the steam
generated as the liquid transferred from inside liquid container (5) is
heated by the contact surface with heating block (2) of liquid holder
(4). Hair is held between the holding surfaces (7, 7) of the pair of
holding parts (1, 1), and under the action of the steam sprayed from the
