Abstract: The invention relates to a hair styling appliance (1) for curling and straightening hair, comprising: a first and a second elongate jaw (2, 3) that are pivotable with respect to one another, the first jaw (2) having a first housing (6) bearing a first flat internal treatment surface (4), and the second jaw (3) having a second housing (7) bearing a second flat internal treatment surface (5), the internal surfaces (4, 5) being intended to pinch a lock of hair, at least one heating element (41, 51) intended to heat at least one internal treatment surface (4, 5). According to the invention, the greatest width l1 of the first housing (6) is less than or equal to 90% of the greatest width l2 of the second housing (7), and at least one of the first housing (6) and the second housing (7) is asymmetric with respect to the median plane in longitudinal section of said first housing (6) or said second housing (7), respectively.

Abstract: A spacing accessory is selectively deployable with a hair treatment tool. In a first aspect, an assembly includes (1) a hair treatment tool with opposed heating surfaces disposed on two arms configured to open, to allow hair to be inserted between the heating surfaces, and close, to press hair between the heating surfaces, and (2) a spacing accessory selectively deployable to maintain the heating surfaces in a spaced relationship, when the arms are closed. In a second aspect, a spacing accessory is configured for removable attachment to a hair treatment tool of the aforementioned type, with the spacing accessory including a spacing member configured to extend between the two arms of the tool to maintain a spaced relationship between the heating surfaces when the arms are closed.
