PURPOSE:A hair dye that is composed of the first agent containing, as an essential component, an oxidation color and the second agent containing, as an essential component, a bromate salt, but not hydrogen peroxide and iron ion is added to at least one agent, thus showing high stability, low irritation and no hair injury. CONSTITUTION:The objective hair dye is composed of the first agent containing an oxidation color such as 2-amino-4-nitrophenol as an essential component and the second agent containing a bromate salt such as sodium bromate or aluminum bromate as an essential component and iron ion is added one of the two components or both components. The amount of the bromate salt is 0.1-20wt% based on the total second agent and the amount of iron ion is 10<-4>-5wt%, based on the second agent, calculated as iron. Since the oxidation power of bromate is mild to develop good and mild dyeing effect without injury or decoloration of hairs. Further, the resultant dye is prepared into an aerosol form.
