When electric power is supplied to the pump 91, the composition of this embodiment is sprayed from the nozzle 93, and the composition is guided to the outside of the device 10 through the second flow path 13B. When electric power is supplied to the motor 71, the fan 72 is activated, and the air flow sent out by the fan 72 is blown out of the device 10 through the first flow path 13A. The particle size of the composition sprayed in a mist form may be, for example, 20 μm or more and 200 μm or less. Here, the particle size refers to the volume average particle size measured by laser diffraction scattering method.

FIG. 4 is a schematic diagram for explaining the diffusion of the mist-like composition (mist composition M) of this embodiment (the mist-like composition in FIG. 4 is shown in a circular shape). The mist composition M sprayed from the second flow path 13B is attracted and diffused by the air flow A sent from the first flow path 13A. As a result, the composition of the present embodiment is suppressed from being applied locally to hair or skin, and can achieve highly uniform application. Moreover, when the air is heated by the heater 81 of FIG. 2, the application of the composition of this embodiment and the drying of this composition can be performed simultaneously.

＜＜Examples 4 to 7＞＞ The hair compositions of Examples 4 to 7 described in Table 4 below were applied in the form of mist to hair bundles (length approximately 30 cm, mass 10 g) that were washed and dried with a towel. This application method is to blow hot air as an air flow (temperature around 80°C, wind speed 20 m/s) from a device having an air blowing part and a mist generating part to the hair bundle, and apply the mist-like hair composition 200 for 3 minutes. mg. In addition, the particle size of the mist composition sprayed from the device was measured using a particle size distribution meter "AEROTRAC II" manufactured by MicrotracBEL Corporation. In this measurement, the measurement was performed under the conditions of using the lens "f100 lens", the exposure time "10 seconds", and the distance between the mist composition and the lens "50 mm", and the average value of the volume average particle diameter of 20 measurements was Let it be "the particle size of the mist composition".

Table 4 below shows the results of evaluating the surface smoothness of the hair bundles after applying the hair compositions of Examples 4 to 7. Examples 5 to 7 prepared with a nonionic surfactant showed better smoothness than Example 4.

＜＜Reference Examples 1～2＞＞ Wash the hair attached to the human head model and wipe off the water with a towel, and then apply 0.3 g of a commercially available liquid hair composition ("PLARMIA DAY ESSENCE" manufactured by Milbon Corporation) added with red pigment to the human head. Hair on one side of the head model. This application was performed by the processing of Reference Examples 1 and 2 below. Reference example 1: From a device having an air blowing part and a mist generating part, hot air (temperature around 80°C, wind speed 20 m/s) is blown while combing, and the above-mentioned liquid hair composition in a mist form is applied. Reference example 2: Apply the above-mentioned liquid hair composition spread on the palm of your hand.
