The invention relates to a device for dispensing a small quantity of a liquid product, comprising a dispensing head (9) comprising an injection nozzle (7) to dispense a desired quantity of liquid product. The dispensing head (9) comprises an inlet (2) connected to a source of the liquid product (12) and an outlet (3) provided with the injection nozzle (7). It comprises a first valve (10) and a second valve (11) installed in series. The device comprises a control system (17) to command an opening sequence of the first valve (10) and of the second valve (11), resulting in a time of concomitant opening of the valves.
