The pulses have at least one pulse duration and a total energy all predetermined to effectively vary a characteristic of the hair fibers owing to absorption of light of the pulses by the hair fibers. By virtue of the directing of the pulses of light towards the hair fibers and absorption of light of the pulses by the hair fibers, at least one selected characteristic of the hair fibers is changed, the one selected characteristic being hair curvature, hair fiber thickness, or hair length.
