Abstract: A hair-cutting head (10) for a hair-cutting device (100) having two sets (22, 24) of light sources which are configured to emit light predominantly in different respective wavelength bands. A first set (22) emits light in a wavelength band of 400-500 nm. A second set (24) emits light in a wavelength band of 500 nm and above. For improved eye safety, the first set of light sources is arranged so that its light output is projected onto the user's skin (23) during operation only via a central region (56) of a skin-contacting area (54) of the hair-cutting head (10). The second set (24) of light sources is arranged so that its light output is provided on the user's skin during operation only via a peripheral region (58) of the same skin-contacting area. This arrangement aims to make it more likely that the light of the first set (24) of light sources is fully shielded by the contact of skin to the hair-cutting head during normal operation, protecting the eyes from this light.

Abstract: According to an aspect, there is provided a method for determining a value of a skin parameter for skin of a subject. The method comprises receiving (510) a first sensor signal that is output by a first light sensor that is arranged to receive light emitted by a first light source after interaction of the emitted light with the skin. The first sensor signal is output while the first light source operates according to a first duty cycle to intermittently emit the light, and the emitted light has a first central wavelength. The method also comprises receiving (520) a first modulation reference signal that is related to the first duty cycle; integrating (530) a first function output signal, resulting from a function of the first sensor signal and the first modulation reference signal, to determine a first integrated value; determining (540) a first number of cycles of the emitted light that are required for the first integrated value to exceed a first threshold value; and determining (550) the value of the skin parameter based on the determined first number of cycles.
