Abstract
A dispenser for applying a treatment solution to selected strands of hair includes a reservoir and a dispensing nozzle. The nozzle is an elongate, preferably conical member, having one or more slots extending from and dividing the tip into tines. The side walls of the slot converge inwardly from one side of the nozzle, a through bore extends from the base of the slot to the base of the nozzle, and at least one of the tines is shorter than the other. The reservoir may be a squeezable bottle or, in the preferred embodiment, an open top container having a handle projecting from one side with a lever arm pivotally connected to the outer end of the arm and mounting a plate-like piston slidably received in the container.
