A spray head for an aerosol tank, and an aerosol tank having a spray head is provided, which includes a fluid exit valve for spraying a low-solvent fluid. The fluid exit valve of the aerosol tank defines an axial fluid exit direction. The spray head includes a capillary tube for routing the fluid and for nozzle-less spraying of the fluid. An entry end of the capillary tube is axially joined to the fluid exit valve when the spray head has been seated on the aerosol tank. An exit end of the capillary tube is open to the ambient atmosphere. In the spray head, the capillary tube runs from the entry end to the exit end in an arc of approximately 90°.
