A system for producing preferential damage to hair exiting mammalian skin. A agent having an average diameter for enabling the agent to penetrate the hair duct is selected. The agent is designed to attach to, or become physically incorporated into, the hair shaft, the hair follicle, the hair bulb or the hair duct. The agent has an electromagnetic radiation absorption characteristic which enables the agent to absorb a first wavelength of electromagnetic radiation from a skin-penetrating electromagnetic radiation source, such as a laser. The agent is applied to the skin so that the agent penetrates the skin and attaches to or becomes physically incorporated into the hair shaft, the hair follicle, the hair bulb or the hair duct. The agent is exposed to the first wavelength of electromagnetic radiation and absorbs the first wavelength of electromagnetic radiation.
