A cosmetic article for dyeing the hair is provided to reduce the time of hair dyeing, increase dyeable color range, reduce stains caused by dyeing operation by eliminating use of liquid formulation support, and eliminate rinsing or shampooing and/or drying of keratinic fiber by using heat transfer. A cosmetic article for dry-dyeing the hair comprises a porous flexible substrate and at least one direct dye powder or direct dye precursor powder capable of dyeing the hair through heat transfer, wherein the substrate and the direct dye or direct dye precursor are bound together through non-covalent bond; the porous flexible substrate is selected from foam type cellulose substrate or nonwoven fiber substrate; and the cosmetic article is prepared by dry impregnation process using the alternating electric field. Further, a thickness of the porous flexible substrate is 0.5 to 20 mm.
