As shown in the following Table 1, by using the pretreatment agent, it is possible to confirm that the "roots of the hair" to give an impression of a large amount of hair and the improvement of the arrangement of hair ends are confirmed.

(Hair treatment: Examples 2a to 2b)

As Example 2a, the same hair treatment as in Example 1a was carried out. As Example 2b, a hair treatment was performed in which the hot water washing which had been carried out between application of the pretreatment agent and the post treatment agent (I) in Example 1a was changed between the post treatment agent (I) and the post treatment agent (II) .

The following Table 2 shows the evaluation results of the hair treatment of Examples 2a to 2b. As in Table 1, the evaluation was made by the total of three or more evaluators. As shown in Table 2, it can be confirmed that the continuous application of the post-treatment agent (I) and post-treatment agent (II) was excellent in "arrangement of hair ends" and "thickness of hair" It can also be confirmed that the hot water cleaning of the post-treatment agent (I) and post-treatment agent (II) is suitable for the softness of the hair.

Separately from the above Examples and Comparative Examples, a cream phase post-treatment agent (I) having a pH of not less than 4.5 and not more than 6.5 and a cream phase post-treatment agent (II) having a pH of not less than 4.5 and not more than 6.5 were prepared by mixing water and a raw material Only the post-treatment agent (I) of Example 6 was in the form of a gel). The blended raw materials and compounding concentrations are shown in Tables 3 to 8 below. For pH adjustment, lactic acid, 2-amino-2-methyl-1-propanol or arginine was used.

The evaluation items in the following Tables 3 to 8 show evaluation results after hair treatment performed in the same manner as in Example 1.

In Table 3, it can be confirmed that when the amino-modified silicone is blended in the post-treatment agent (I) by adjusting the amount of the amino-modified silicone and the highly polymerized methylpolysiloxane, the hair is trimmed and the thickness of the hair is improved. It is also confirmed that when the post-treatment agent (II) is blended with highly polymerized methylpolysiloxane, the ends of the hair are trimmed and the thickness of the hair becomes good.

Table 4 shows evaluation results of "arrangement of hair ends" confirmed by visual observation and "moist feeling" which is a feeling of being moisturized. The evaluation in the following Table 4 is the contrast between Examples 4a and 4b, and the contrast between Examples 4a and 4c. In Table 4, it can be confirmed that the evaluation results were excellent in the pH range of 6.5 or less.

In Table 6, it can be confirmed that the cream formulations are suitable for the arrangement and moisturizing of the hair.
