Method, compositions, and kits for coloring hair

Abstract

A method for altering the color of hair comprising applying a bleach composition containing persulfate salts and at least one oxidizing agent to the desired strands of hair for a period of time sufficient to bleach the hair, removing the bleach composition from the hair but leaving at least some residual oxidizing agent on the bleached hair strands, then treating the hair with a colorant composition containing at least one dye operable to color hair in the presence of the residual oxidizing agent found on the bleached hair strands, said colorant composition being free of any oxidizing agents operable to react with the dye present therein to form color, whereby upon contact with the colorant composition, the hair strands treated with the bleach composition having residual oxidizing agent thereon will react with the dye present in the colorant composition to cause the bleached hair strands to become colored, while any remaining unbleached hair will not become colored by contact with the colorant composition and a kit and shampoo composition for use with the method.

       28 . A kit for applying highlights to hair comprising (i) a first receptacle containing a oxidizing agent composition, (ii) a second receptacle containing a persulfate composition, (iii) a comb through applicator for affixing to the first or second receptacle; and (iv) a third receptacle containing a colorant composition free of oxidizing agents but containing at least one oxidative dye reactive with the oxidizing agent in the first receptacle oxidizing agent composition.  
   
   
       29 . The kit of  claim 28  wherein the oxidizing agent in the first receptacle comprises hydrogen peroxide.  
   
   
       30 . The kit of  claim 28  wherein the first receptacle is a plastic bottle.  
   
   
       31 . The kit of  claim 28  wherein second receptacle is a tube, packette, or jar.  
   
   
       32 . The kit of  claim 28  wherein the comb on applicator is affixed to the first receptacle.  
   
   
       33 . The kit of  claim 28  wherein the third receptacle is a tube.  
   
   
       34 . The kit of  claim 28  which additionally comprises a hair conditioner composition contained in a receptacle that is a tube or a packette.  
   
   
       35 . The kit of  claim 28  wherein the different components are stored in a box.  
   
   
       36 . A shampoo composition comprising, at least one primary intermediate and, optionally, a coupler for the formation of oxidation dyes, and at least one anionic surfactant, wherein said composition is free of oxidizing agents reactive with the primary intermediate and coupler to form oxidation dyes.  
   
   
       37 . The composition of  claim 36  further comprising at least one thickener.  
   
   
       38 . The composition of  claim 36  further comprising at least one solvent.  
   
   
       39 . The composition of  claim 36  wherein the at least one primary intermediate comprises p-phenylenediamine.  
   
   
       40 . The composition of  claim 36  comprising, by weight of the total composition: 
 0.0001-6% of at least one primary intermediate, and optionally a coupler for the formation of oxidation dyes,    0.1-25% of an anionic surfactant; and    0.001-5% of a thickening agent.
