There is provided a hair cutting device for cutting hair on a body of a subject. The hair cutting device comprises at least one light source for generating laser light at two or more specific wavelengths corresponding to wavelengths absorbed by one or more chromophores in hair; and a cutting element comprising an optical waveguide for receiving light from the at least one light source. The optical waveguide comprises a cutting face, the cutting face being arranged to contact hair as the hair cutting device is moved across the skin of the body of a subject. The cutting face is arranged essentially parallel to the long axis of the optical waveguide. The optical waveguide is arranged to allow the light generated by the at least one light source to couple into hair when hair is close to or in contact with the optical waveguide. The at least one light source is configured to generate laser light having a first wavelength and a series of pulses of laser light having a second wavelength.
