A spray head or spray head insert for use in at least one of a shower head, an industrial spray head and an agricultural spray head including a plurality of groups 2a, 2b, 2c of nozzles 20 to 27, each group of nozzles 20 to 27 having at least two nozzles 20 to 27 that are suitable for issuing jets of fluid from a surface of the spray head and are dimensioned and oriented so that fluid exiting the said at least two nozzles under pressure collides and interacts substantially unimpeded by surrounding structures, characterised in that following the collision the fluid breaks into droplets, in that the at least two nozzles 20 to 27 are orientated at an included angle of between 40° to 140°, and in that the spray head is shaped and dimensioned to create, in use, a turbulent fluid flow in each nozzle.
