  • Patent number: 7074244
    Abstract: 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: Grant
    Filed: July 3, 2003
    Date of Patent: July 11, 2006
    Assignee: Unilever Home & Personal Care USA, division of Conopco, Inc.
    Inventors: Alexander C. Chan, Padmaja Prem, Katherine Jacobs-Dube, John Brian Bartolone
  • Patent number: 6994733
    Abstract: A method for electrochemically dyeing, highlighting or tinting hair is provided which includes first applying to the hair an oxidative dye precursor mixture containing a primary intermediate having a standard Redox potential that is less than about 1V. This precursor mixture on the hair in then contacted with an electrode system that has sufficient voltage to electrochemically oxidize the primary intermediate to produce a colored dye through a coupling reaction. A system or kit for carrying out the method is also provided.
    Type: Grant
