PROBLEM TO BE SOLVED: To provide a means of attaining permanent or semipermanent dehairing to remove an unnecessary hair without the risk of a scar and infection (frequently occurs in an electrolytic method) targeting a follicle after dehairing from it, and its method. SOLUTION: In this method, a permanent/semipermanent dehairing composition, which is activated by a chromophore, a photosensitizer, an ultrasound sensitive agent, and a chemical means, and formed in a non-spherical minute particle having a size of not smaller than 10μm but not larger than 50μm, is introduced after removing an unnecessary hair, in a follicle to alter and/or kill the cell contributing to the growth of a hair by activating the compound by electromagnetic irradiation, ultrasonic irradiation, etc. COPYRIGHT: (C)2009,JPO&INPIT
