Patent number: 7074244Abstract: A sequential method for dyeing hair which comprises: contacting the hair with a substantially inactive dye precursor mixture containing at least one primary intermediate and an optional coupler for a period of time, followed by applying a means for aligning the hair and distributing the oxidative dye precursors uniformly, followed by contacting the hair with a developer mixture capable of oxidizing the hair dye precursors to react and form hair color molecules.Type: GrantFiled: July 3, 2003Date of Patent: July 11, 2006Assignee: Unilever Home & Personal Care USA, division of Conopco, Inc.Inventors: Alexander C. Chan, Padmaja Prem, Katherine Jacobs-Dube, John Brian Bartolone

Patent number: 7066968Abstract: The present invention relates to a 2-step methods, and compositions for providing more vibrant, natural and long-lasting color to hair and at the same time reducing hair fiber damage associated with alternative current methods. In the first step the hair is contacted for a period of time with a dye precursor mixture containing specific oxidative hair dye precursors under conditions where these dyes are substantially inactive. Color is then developed in a second step by contacting the hair with a mixture of a peroxide compound and a persulfate salt. Surprisingly the 2-step method leads to considerable “lift” or lightening without negatively impacting the coloring ability of the oxidative dye. The invention also relates to kits providing the means to accomplish these steps.Type: GrantFiled: March 2, 2004Date of Patent: June 27, 2006Assignee: Unilever Home & Personal Care USA, division of Conopco, Inc.Inventors: Alexander C Chan, Stella Arcella, John Brian Bartolone, Allan Robert Burger
