Abstract: A hair cutting device (10) is provided comprising a cutter unit (11), a skin stretcher (12) and slit adapting means. The cutter unit (11) comprises a skin-contact surface for dragging over a skin surface (21) in a shaving direction (55), a front surface arranged in front of the skin-contact surface in the shaving direction (55), and a laser beam exit window arranged in the front surface for allowing a hair cutting laser beam (13) to cut a hair (22) near the skin surface (21) in front of the front surface. The skin stretcher (12) is positioned in front of the cutter unit (11), according to the shaving direction (55), and comprises a stretcher surface for dragging over the skin surface (21) together with the skin-contact surface, such that a skin dome (23) is formed by the skin surface (21) in a slit between the skin stretcher (12) and the cutter unit (11). The slit adapting means are provided for adapting at least one dimension (51, 52, 54) of the slit for controlling a shape of the skin dome (23).
