Abstract: An apparatus and method for facilitating program changes. The apparatus and method include a controller for detecting a change program request and for outputting change event data when a change event is detected. A non-active video information replacement module is coupled to the controller for receiving non-active video information and the change event data. When the replacement module receives change event data, a clear code generator generates clear code data that replaces non-active video information, and the non-active video information replacement module generates modified non-active video information. The modified non-active video information is provided to an output stage, whereupon the clear code data resets a non-active video information field within a display device, thereby preventing the display of erroneous information by a display within the output stage. Thereupon, clear code data is synthetically inserted within non-active video information upon the occurrence of a change event.

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.

Abstract: 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.

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 having at least 50% of the molecules comprising these precursors are in their non-anionic form, for a period of time, followed by contacting the hair with a developer mixture capable of oxidizing the hair dye precursors to react and form hair color molecules.

Abstract: A two step method of coloring hair is described. The hair is first contacted for a period of time with a dye precursor mixture containing an oxidative dye, specific fatty components and one or more water miscible organic solvents. Color is then developed in a second step by contacting the hair with one or more oxidizing agents. Greater color intensity and longevity are achieved when the fatty component in the dye precursor mixture contains at least one fatty amine and the fatty ingredients and organic solvents satisfy the relationship, ?FC<0.037(?OS)2?3.35(?OS)+63, where ?FC and ?OS are respectively the total weight of fatty ingredients and the total weight of water miscible organic solvents in the precursor mixture.

The present invention also relates to a method for coloring hair which comprises contacting said hair with a hair coloring composition as described above.
