The present invention relates to an applicator (1) which allows for precise, non-messy and even application of a hair treatment composition to a hair strand. The applicator (1) comprises a plate (10) movably jointed by a connection (3)) to a well (20), a first fin (70) and a second fin (71) which project from the internal surface (101) of the plate (10) and point to one another and a fluid metering means comprising a lower metering means (50) positioned on the internal surface of the wall (202) of the well (20) adjacent the rim (222). When said applicator (1) is in a closed state, the lower metering means (50) and the first fin (70) are substantially juxtaposed to provide said fluid metering means.
