Patent number: 6908491Abstract: A method for color-revitalizing a color tone of hair that involves applying a color-revitalizing composition to hair previously dyed with an oxidative hair dye composition. The color-revitalizing composition, which has a color determined by the color of the oxidative hair dye composition and contains at least one direct dye, revitalizes the color tone originally obtained by after dyeing with the oxidative hair dye composition.Type: GrantFiled: October 23, 2001Date of Patent: June 21, 2005Assignee: The Andrew Jergens CompanyInventors: Vince Fischer, Masahiko Sakai, Satoshi Onitsuka, Hajime Miyabe, Hiroshi Ikeda, David Ferguson

Patent number: 6824387Abstract: A mirror for checking dyed hair color has a mirror and a colored filter formed on part or the whole of the surface of the mirror. The colored filter is formed such that the color of the reflected image of hair from the colored filter is the same as the dyed hair color for when the hair has been dyed with a particular hair dye. By using this mirror for checking dyed hair color, it is possible to easily predict hair color after dyeing for any given initial hair color, thus making it possible to easily select a hair dye for obtaining a desired dyed hair color.Type: GrantFiled: December 26, 2001Date of Patent: November 30, 2004Assignee: Kao CorporationInventors: Masahiko Sakai, Satoshi Onitsuka, Mitsuo Asano

Patent number: 5538720Abstract: A composition for hair treatment comprising at least two compositions (A) and (B) that are kept separate until application and that upon mixing increase in viscosity while generating heat, wherein one composition (A) comprises an essentially anhydrous mixture of a physiologically compatible salt that generates heat when mixed with water, and at least one thickening agent, and composition (B) comprising at least one polyalcohol that is liquid at 25.degree. C. and is selected from the group consisting of polyethyleneglycol, polypropyleneglycol, glycerol and diglycerol and, optionally, additional hair conditioning. A process for hair treatment, wherein composition (B) is first mixed with water and then blended with composition (A), whereby, while generating heat, a viscous gel develops that is applied onto the hair where it provides an enhanced conditioning effect due to improved penetration at higher temperature.Type: GrantFiled: August 17, 1993Date of Patent: July 23, 1996Assignee: Kao CorporationInventors: Madeleine Jendryssek-Pfaff, Satoshi Onitsuka
