Abstract: The invention is directed to a hair treatment appliance (1), comprising two elongate tong elements (2, 3) which are movable relative to each other and between which the hair is insertable with the tongs in an open position and between which the hair may be pulled through with the tongs in a closed position. Provision is made for an arrangement for generating steam introducible between the two tong elements (2, 3). A device is provided which, using the generated steam, is capable of introducing a hair treatment agent between the two tong elements (2, 3). The appliance (1) is not only suitable for use as a steam crimper but affords the added possibility of being used for the application of a hair treatment agent to the hair and the treatment of the hair with said agent.
