Abstract: Apparatus for curling hair comprises first and second side portions ((12), (14)) which are secured together in a spaced apart relationship via a connector portion (16). The connector portion (16) is positioned substantially centrally with respect to each side portion. The connector portion (16) has a length of not more than 20 mm. The side portions ((12), (14)) are fabricated from a material which is both resilient and thermally conductive. The first side portion (12) is substantially flat and the second side portion (14) is configured such that it is provided with two fixed states: a first state in which the first side portion is convex in shape and bends away from the second plate; and a second fixed state in which the first side portion is concave in shape and folds over to cover both the connector portion and the first side portion.
