Abstract
A device for applying a thin, even layer of a liquid medicament to the scalp or other hair-covered skin surface while minimizing the amount of liquid wetting the hair is disclosed. The device includes a liquid reservoir and an applicator body having at least one downwardly extending tooth, each tooth having an internal fluid channel in communication with the reservoir, and having orifice ports adjacent to but above the tooth end. Metered doses of liquid are delivered to the orifice ports by operation of a manually operated pump or other fluid transport means.
