The specification discloses a dispenser for automatically mixing controlled amounts of liquid additive to the shower water. The dispenser is attachable to the water inlet pipe of an ordinary shower head and includes a plastic refillable container for holding the liquid additive and dispensing it under the flow of gravity. A valve is positioned over the mouth of the receptacle for controlling the flow of liquid additive. A dispensing tube assembly communicates with the valve for allowing liquid additive to flow by gravity to a portion of the dispensing tube extending subjacent the nozzles of the shower head. A first series of discharge openings along the bottom portion of the dispensing tube assembly drips a continuous flow of liquid additive into the stream of shower water after it exits from the nozzle. In another embodiment, some of the spray of water exiting from the shower head is directed into a second series of openings along the portion of the dispensing tube adjacent the front of the shower head for mixing water and liquid additive and discharging it from the series of discharge openings on the bottom side of the dispensing tube.
