The present invention is a hair coater which appropriately delivers an paint liquid without liquid leakage of the paint liquid, and which, in addition, can assure sufficient paint performance, preventing the paint liquid or the like from being directly applied to the
scalp, and the hair coater, which while
combing hair by a comber made up of comb members and a multiple number of
porous coating elements arranged comb-like in a row along the comb members, is able to apply the paint liquid in a container being attached to the hair by means of the
porous coating elements, and is characterized in that the paint liquid retention force of the
porous coating elements falls within a range of 120 to 250 mm. The present invention also includes a coater-equipped cosmetic container with the aforementioned hair coater.
