[0033] The present invention will be specifically explained below based on test examples, but the present invention is not limited to these. In the following examples, the blending amounts are expressed in mass %.

[0034] [Test Example 1: Usage Evaluation] The compositions shown in Table 1 below were prepared according to conventional methods. Polyvinylpyrrolidone with a K value of 30 was used. Expert panelists evaluated the compositions according to the evaluation criteria. The results are shown in Table 1.

[0035] [Table 1]

[0036] (Evaluation criteria for texture) After washing a curling human hair bundle (Kinky Curl Virgin Cuticle Aligned Hair Products, manufactured by Xuchang Yousheng Hair Products Co., Ltd.) with a commercially available shampoo, the entire hair bundle was immersed in each test solution, left to stand at room temperature for 5 minutes, and then rinsed with water. The hair bundle was blow-dried using a hair dryer, and the feel (touch) of the hair bundle after drying was evaluated by running a finger from the root to the tip according to the following criteria. ◎: No feeling of catching 〇: The ends of the hair feel tangled, but the hair is smooth to the touch. △: The hair feels tangled from the middle to the ends, but is smooth to the touch. ×: Hair feels tangled and difficult to run your fingers through.

[0037] (Evaluation criteria for extensibility) After washing a curling human hair bundle (Kinky Curl Virgin Cuticle Aligned Hair Products, manufactured by Xuchang Yousheng Hair Products Co., Ltd.) with a commercially available shampoo, the entire hair bundle was immersed in each test solution, left to stand at room temperature for 5 minutes, and then rinsed with water. The hair was blown using a hair dryer to straighten it, and the hair bundle was observed after drying. The curl extensibility was evaluated according to the following criteria. ◎: No curls ○: Curls are at the ends of the hair △: Curls are at the root ×: Curly hair all over

[0038] (Evaluation criteria for ease of organization) After washing a curling human hair bundle (Kinky Curl Virgin Cuticle Aligned Hair Products, manufactured by Xuchang Yousheng Hair Products Co., Ltd.) with a commercially available shampoo, the entire hair bundle was immersed in each test solution, left to stand at room temperature for 5 minutes, and then rinsed with water. The hair was then blow-dried, and the manageability of the dried hair was evaluated according to the following criteria. ◎: Spreads evenly and is easy to manage 〇: Spreads evenly and is easy to manage △: Spreads slightly unevenly, but is easy to manage ×: Spreads unevenly and is difficult to gather

[0039] The composition containing components (A), (B), and (C) is smooth to the touch, making it easy to style the hair bundle with a hand, and the low friction on the hair surface is thought to minimize physical damage caused by rubbing the hair. The composition containing components (A), (B), and (C) tends to straighten curls when wet hair is blow-dried, improving hair flexibility and suppressing curl formation, thereby improving hair quality. The composition containing components (A), (B), and (C) is effective from the roots of the hair bundle to the fine tips, improving hair quality and making it easier to style, as hair blow-dried after shampooing spreads evenly and is easy to manage.

[0040] [Test Example 2: Usage Evaluation] The compositions shown in Table 2 below were prepared according to conventional methods. Polyvinylpyrrolidone with a K value of 30 was used. Evaluation was carried out by expert panelists according to the evaluation criteria. The evaluation criteria for texture were the same as those in Test Example 1. The results are shown in Table 2.

[0041] [Table 2]

[0042] (Foaming evaluation criteria) Each test solution was applied to the entire surface of a curled human hair bundle (Kinky Curl Virgin Cuticle Aligned Hair Products, manufactured by Xuchang Yousheng Hair Products Co., Ltd.), and then the hair was washed for one minute. The foaming rate during washing was observed and evaluated according to the following criteria. ◎: The foam spreads over the entire hair strand, and the amount of foam increases as you wash your hair. 〇: The foam spreads throughout the hair strands, and the amount of foam is maintained throughout the wash. △: The foam spreads over the entire hair strand, but the amount of foam decreases as you wash your hair. ×: Lathers, but the foam does not spread to the entire hair bundle

[0043] [Test Example 3: Usage Evaluation] The compositions shown in Table 3 below were prepared according to conventional methods. Polyvinylpyrrolidone with a K value of 30 was used. Evaluation was carried out by expert panelists according to the evaluation criteria. The evaluation criteria for feel and manageability were the same as those in Test Example 1. The results are shown in Table 3.

[0044] [Table 3]

[0045] Examples of preparations are shown below. The preparation example in Table 4 is a hair treatment. The preparation example in Table 5 is a shampoo. The preparation example in Table 6 is an after-bath treatment.
