Formulation Examples 5b to 5d were employed for -5d (Comparison between Formulation Examples 5b to 5d and Formulation Example 5a). The evaluation results are shown in Table 2.

<Preparation of the first agent>
The first agents of Formulation Examples 3a to 3b, 4a to 4b, and 5a to 5d were prepared in a creamy dosage form by blending the raw materials shown in Table 2 below into water.

<Preparation of the second agent>
As the 2nd agent of prescription examples 3a-3b, 4a-4b, 5a-5d, the same thing as the 2nd agent of prescription examples 1a-1d was used.

  As is clear from Table 2, the two-part hair treatment agent of Formulation Example 3b in which kaolin is blended with the first agent as a powder is the formulation of Formulation 3a in which powder (kaolin) is not blended with the first agent. The feeling of thickness was improved as compared with the preparation-type hair treatment agent. In addition, the two-part hair treatment agent of Formulation Example 4b in which kaolin is blended with the first agent is compared with the two-part hair treatment agent of Formulation Example 4a in which powder (kaolin) is not blended with the first agent, The feeling of thickness was improved. From these results, it is considered that the sense of thickness is improved by adding kaolin as a powder to the first agent.

In addition, the two-part hair treatment agent of Formulation Example 5a in which kaolin is blended as powder with the first agent is used in the two-part hair treatment agent of Formulation Examples 5b to 5d in which powder other than kaolin is blended with the first agent. The feeling of thickness improved compared with. From this result, it is considered that blending kaolin as a powder with the first agent is effective in improving the feeling of thickness.
