This disclosure relates to a composition for coloring hair containing comprising a multi-lamellar gel emulsion, which includes a haircolor formulation, and a method of making the same. The multi-lamellar gel emulsion includes about 0.5 wt % to about 4.0 wt % of cosmetically acceptable emulsifying fats, a cosmetically acceptable non-ionic surfactant, a water-soluble suspending polymer, and at least 80 wt % of water.

Compositions for coloring hair including ultra-efficient high aqueous, multi-lamellar emulsion systems, and methods of making the same

The disclosure relates to a method for gradually coloring hair comprising the steps of: a) applying an air oxidation haircolor composition to hair; b) removing the air oxidation haircolor composition from the hair directly after application; and c) repeating a set comprising the steps a) and b) in multiple spaced intervals. The air oxidation haircolor composition can include: 1) at least one primary oxidation dye intermediate; 2) at least one aromatic triol; and 3) water.

Gradual haircolor compositions and methods of using the same

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.

Hair dyeing method including an aligning step

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.

Method for providing more vibrant, natural and long-lasting color to hair

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.
