In addition, when each agent is configured as an aerosol type, the mixture may be applied to the hair after each of the agents is discharged in the form of foam, or the mixture may be mixed on the hair while applying each agent to the hair. good. The mixing method is not particularly limited, and for example, stirring may be performed manually using a stirring rod or brush, or a stirrer, an electric stirrer, or the like may be used. Application of the hair dye or hair bleaching/decoloring agent to the hair can be performed by a known method, for example, a method of applying to the hair with a thinly gloved hand, a comb, or a brush attached to the hair. .

After the mixture has been applied to the hair, a step of rinsing the mixture applied to the hair with water is carried out according to a conventional method after a predetermined period of time has elapsed. Next, a step of washing the hair, preferably using a shampoo composition in a conventional manner, and rinsing with water is carried out. The shampoo composition is not particularly limited as long as it is applied for washing hair, and known shampoo compositions can be applied. Next, a step of rinsing the hair with a rinsing composition and rinsing with water is performed, preferably according to a conventional method. The rinsing composition is not particularly limited as long as it is applied for rinsing hair, and known rinsing compositions can be applied. A known rinse composition can be applied to the treatment step using the rinse composition. Next, a step of drying the hair is carried out, preferably according to conventional methods.
