The device comprises a basin having a wall with a U-shaped indentation for reception of a user's neck. A series of independently adjustable ducts, each of which incorporates several jet heads, each jet head having a number of nozzles arranged to direct streams of water radially inwards, are mounted on the basin. The ducts are connected to a common water inlet manifold and are adjustable to selected stationary positions such that the whole of the user's hair can be simultaneously rinsed. The jet heads are preferably linearly and/or rotationally adjustable with respect to the ducts. Rinsing water is caused to accumulate in a pool at the bottom of the basin by a weir running across the floor and preferably incorporating a narrow gap to provide controlled out-flow of water. The ducts may also be adapted to fit within a conventional backwash basin by means of suitable bracket means.
