Head hair dyeing method

Abstract

There is provided a head hair dyeing method using a two-part hair dye composition which contains a first part containing an alkali agent, a second part containing hydrogen peroxide and a non-aerosol type foamer container for discharging a mixture solution of the first part and the second part as foam, the composition containing a surfactant in at least one of the first part and the second part, the method including discharging the mixture solution as foam, applying the foam to the head hair, and then re-foamed on the head hair.

1 . A head hair dyeing method using a two-part hair dye composition which comprises a first part comprising an alkali agent, a second part comprising hydrogen peroxide and a non-aerosol type foamer container for discharging a mixture solution of the first part and the second part as foam, the composition comprising a surfactant in at least one of the first part and the second part, the method comprising discharging the mixture solution as foam, applying the foam to the head hair, and then re-foaming on the head hair. 
     
     
         2 . The head hair dyeing method according to  claim 1 , wherein the mixture solution applied to the head hair is foamed with fingers. 
     
     
         3 . The head hair dyeing method according to  claim 1 , wherein the foam of the mixture solution is applied to the whole head hair and re-foamed. 
     
     
         4 . The head hair dyeing method according to  claim 1 , wherein the foam of the mixture solution is applied to a part of the head hair and re-foamed. 
     
     
         5 . The head hair dyeing method according to  claim 1 , wherein components (A) and (B) are present in the mixture solution of the first part and the second part:
 (A) 1 to 15% by mass of a surfactant; and   (B) 0.05 to 1% by mass of a higher alcohol,   wherein the mass ratio of component (B) to component (A) (content of component [B]/content of component [A]) is 0.02 to 0.4.   
     
     
         6 . The head hair dyeing method according to  claim 1 , wherein components (A) and (C) are present in the mixture solution of the first part and the second part:
 (A) 1 to 15% by mass of a surfactant; and   (C) 0.1 to 4% by mass of a nonvolatile hydrophilic solvent,   wherein the mass ratio of component (A) to component (C) (content of component [A]/content of component [C]) is 1 to 20.
