Abstract:
A process for producing preferential damage to hair exiting mammalian skin through a hair duct, the hair growing in a hair follicle and having a hair shaft and a hair bulb, the process comprising:selecting an agent having an average diameter for enabling the agent to penetrate the hair duct, the agent comprising a material for at least one of bonding to and becoming physically incorporated into at least one of the hair shaft, the hair follicle, the hair bulb and the hair duct, the agent having an electromagnetic radiation absorption characteristic for enabling the agent to absorb at least a first wavelength of electromagnetic radiation from a skin-penetrating electromagnetic radiation source,applying the agent to the skin so that the agent penetrates the skin and at least one of bonds to and becomes physically incorporated into at least one of the hair shaft, the hair follicle, the hair bulb and the hair duct, andexposing the agent to at least a first wavelength of electromagnetic radiation, whereby the agent absorbs the first wavelength of electromagnetic radiation.
