Abstract: Provided are an oxidation hair dye and a hair bleach, in particular, an oxidation hair dye and a hair bleach effective in use on dyed hair which has solved the problems in using oxidation hair dye or hair bleach, specifically problems such as hair showing a hard and unfavorable texture when treated by oxidation hair dye and hair bleach due to damage to the hair from those agents. An oxidation hair dye characterized by comprising ceramides and/or sterol esters, lecithin or a lecithin derivative and silicones.

Abstract: Hair treating emulsion compositions are resistant to drying after applied to hair and have a formulation permitting easy application to hair. The emulsion composition includes a lubricant, a surfactant and water and further includes 0.5 to 15 wt % of at least one polyhydric alcohol selected from the group consisting of glycerol, diglycerol and dipropylene glycol; 0.005 to 1 wt % of a highly polymerized polyethylene glycol; and 0.05 to 10 wt % of lanolin and/or a lanolin derivative.

Abstract: A first hair coloring agent composition is a hair coloring agent composition comprising (A) one or more compounds selected from the group consisting of p-phenylenediamine, toluene-2,5-diamine and their salts, (B) ?-naphthol and (C) resorcin (with the proviso that p-aminophenol is not contained), wherein the components (A) to (C) are contained in a total amount of 60 to 100% by weight when the total amount of dye components in the hair coloring agent composition is 100% by weight, and based on 1 part by weight of the component (A), the component (B) is contained in an amount of 0.1 to 1 part by weight, and the component (C) is contained in an amount of 0.45 to 1.5 parts by weight. A second hair coloring agent composition is a hair coloring agent composition further comprising (D) p-aminophenol in addition to the components (A) to (C), wherein the components (A) to (D) are contained in given amounts and in given weight ratios.

Abstract: A hair-coloring method comprises coloring hair having virgin hair portions and already-colored hair portions, wherein: (A) the virgin hair portions are colored with an oxidative hair-coloring agent (I) comprising an oxidative dye, ammonia and hydrogen peroxide and having an ammonia concentration of 0.2 to 3.0% by weight and a hydrogen peroxide concentration of 2.5 to 5.0% by weight, and (B) the already-colored hair portions are colored with an oxidative hair-coloring agent (II) comprising an oxidative dye, ammonia and hydrogen peroxide and having an ammonia concentration of 0.1 to 1.5% by weight and a hydrogen peroxide concentration of 0.01 to 2.0% by weight. Hair having virgin hair portions and already-colored hair portions can be colored in a uniform color tone over the whole hair.
