<p>A two-part hair dye comprising a first preparation containing an alkali agent, a second preparation containing hydrogen peroxide, and a non-aerosol foamer container, wherein the first preparation contains the components (A) to (C) mentioned below, the ratio of the mass of the component (A) to the mass of the component (B) (i.e., an (A)/(B) ratio) in the first preparation is 0.3 or less, and the viscosity of the mixed solution is 1 to 300 mPa·s or more. (A): 0.9 to 1.7 mass% of resorcin. (B): a polyoxyalkylene-type nonionic surfactant. (C): a polymer or copolymer having a molar fraction of a diallyl dimethyl quaternary ammonium salt monomer of 70% or more.</p> |
