Method and kit for coloring hair
A kit for coloring hair containing at least one leave on pretreatment composition for application to hair prior to coloring, and a method for coloring hair and improving hair condition and evenness of color deposition in hair that is permanently colored or lightened.
1 . An oxidative hair color kit comprising at least: (a) a receptacle containing an oxidative hair color composition, (b) a receptacle containing a developer composition, wherein (a) and (b) are combined to form a hair color mixture; and (c) a receptacle containing at least one leave on pretreatment composition for application to the hair prior to coloring the hair with the mixture of (a) and (b).
2 . The kit of claim 1 wherein the leave on pretreatment composition comprises a low molecular weight diffusible oil.
3 . The kit of claim 2 wherein the low molecular weight diffusible oil comprises coconut oil, mineral oil, esters having a molecular mass of 200 to 600 grams/mol, or mixtures thereof.
4 . The invention is further directed to a hair bleach kit comprising (a) a receptacle containing a developer, (b) a receptacle containing a persulfate bleach composition, and (c) a receptacle containing a leave on pretreatment composition for application to the hair prior to bleaching the hair with the hair bleach mixture formed by combining (a) and (b).
5 . The kit of claim 4 wherein the bleach is in a powdered form.
6 . The kit of claim 4 wherein the pretreatment composition comprises a low molecular weight diffusible oil.
7 . The kit of claim 6 wherein the oil is coconut oil, mineral oil, or esters having a molecular mass of 200 to 600 grams/mol, or mixtures thereof.
8 . A semi-permanent hair color kit comprising (a) a receptacle containing a semi-permanent dye composition, and (b) a receptacle containing a leave on pretreatment composition for application to the hair prior to coloring the hair with the semi-permanent dye composition.
9 . The kit of claim 8 wherein the leave on pretreatment composition comprises a low molecular weight diffusible oil.
10 . The kit of claim 9 wherein the oil comprises coconut oil, mineral oil, esters having a molecular mass of 200 to 600 grams/mol, or mixtures thereof.
11 . A hair highlighting kit comprising (a) a receptacle containing a developer composition, (b) a receptacle containing a persulfate bleach composition, (c) at least one application device, and (d) a receptacle containing a leave on pretreatment composition for application to the hair prior to highlighting the hair with the mixture of (a) and (b).
12 . The kit of claim 11 wherein the pretreatment composition comprises coconut oil, mineral oil, or esters having a molecular mass of 200 to 600 grams/mol.
13 . A lowlighting kit comprising (a) a receptacle containing a developer composition, (b) a receptacle containing a lowlight dye composition, (c) an applicator; and (d) a receptacle containing a leave on pretreatment composition for application to the hair prior to applying lowlights to the hair with the applicator and the mixture of (a) and (b).
14 . The kit of claim 13 wherein the pretreatment composition comprises coconut oil, mineral oil, or esters having a molecular mass of 200 to 600 grams/mol.
15 . A method for permanently coloring hair comprising:
(a) applying a leave on pretreatment composition to the hair to be colored,
(b) coloring the pretreated hair with a hair color composition.
16 . The method of claim 15 wherein the pretreatment composition comprises a low molecular weight diffusible oil.
17 . The method of claim 16 wherein the oil comprises coconut oil, mineral oil, or mixtures thereof.
18 . The method of claim 15 wherein the hair coloring composition is an oxidative hair color mixture prepared by combining a developer and oxidative hair color composition.
19 . The method of claim 15 wherein the hair coloring composition is a hair bleach mixture prepared by combining a powdered bleach composition and a developer.
20 . A method for improving hair conditioning and/or evenness of color deposition in hair that is permanently colored comprising applying a leave on pretreatment composition containing a low molecular weight diffusible oil to the hair prior to coloring the hair.
21 . The method of claim 20 wherein the permanent coloration is an oxidative dye or bleach.
22 . The method of claim 20 wherein the pretreatment composition comprises a low molecular weight diffusible oil.
23 . The method of claim 22 wherein the oil comprises coconut oil, mineral oil, or mixtures thereof.
