[0085] <Preparation of hair bundles and evaluation wigs> Hair bundle samples (same human hair, hair diameter: 60-100 μm) were treated with a bleaching agent (Hoyu Co., Ltd., Recepowder Bleach EX) at 30°C for 30 minutes, then rinsed with water, shampooed, and dried with a hairdryer. From the treated hair bundle samples, those with similar brightness and texture were selected and designated as chemically treated hair samples. Ten g of chemically treated hair samples were washed with water, then cleansed with a hair cleansing agent (Hoyu Co., Ltd., "Promaster Color Care Stylish Shampoo"), and then washed again with water. Next, the samples were towel-dried, and 0.2 g of the hair cosmetic compositions of the examples and comparative examples were evenly applied to the entire chemically treated hair sample. The hair bundles were then dried with a hairdryer and used as evaluation bundles. The same treatment as described above was performed on a wig (made from the same human hair, with a hair diameter of 60-100 μm), except that the amount of hair cosmetic composition applied was changed to 1.0 g, and this was used as an evaluation wig.

[0086] <<Evaluation of softness>> Ten expert panelists ran their fingers through the hair strands used for evaluation, from the middle to the ends, and assessed the softness of the hair. They rated the softness on a scale of 5 points for very soft, 4 points for soft, 3 points for slightly soft, 2 points for not soft, and 1 point for not soft at all. The average score for each panelist was calculated, and the evaluation results were as follows: an average of 4.6 points or higher was given an "A grade," 3.6 points or higher but less than 4.6 points was a "B grade," 2.6 points or higher but less than 3.6 points was a "C grade," 1.6 points or higher but less than 2.6 points was a "D grade," and 1 point or higher but less than 1.6 points was an "E grade." The results are shown in Tables 1 to 3.

[0087] <<Evaluation of finger-feel>> Ten expert panelists ran their fingers through the hair strands used for evaluation, from the middle to the ends, and evaluated how easily their fingers could run through the hair. They rated the hair's texture on a scale of 5 points for very smooth texture, 4 points for good texture, 3 points for slightly good texture, 2 points for poor texture, and 1 point for very poor texture. The average score for each panelist was calculated, and the evaluation results were as follows: an average of 4.6 points or higher was given an "A grade," 3.6 points or higher but less than 4.6 points was a "B grade," 2.6 points or higher but less than 3.6 points was a "C grade," 1.6 points or higher but less than 2.6 points was a "D grade," and 1 point or higher but less than 1.6 points was an "E grade." The results are shown in Tables 1 to 3.

[0088] <<Evaluation of coherence>> Ten expert panelists ran their fingers through the hair strands used for evaluation, from the middle to the ends. They then visually inspected the hair strands and evaluated them on a scale of 1 to 5 for very good manageability, 4 for good manageability, 3 for slightly good manageability, 2 for poor manageability, and 1 for very poor manageability. The average score for each panelist was calculated, and the evaluation results were as follows: an average of 4.6 points or higher was given an "A grade," 3.6 points or higher but less than 4.6 points was a "B grade," 2.6 points or higher but less than 3.6 points was a "C grade," 1.6 points or higher but less than 2.6 points was a "D grade," and 1 point or higher but less than 1.6 points was an "E grade." The results are shown in Tables 1 to 3.

[0089] <<Evaluation of weight>> Ten expert panelists ran their fingers through the hair of the evaluation wig from the middle to the ends to check its weight, and then visually inspected the evaluation wig and evaluated it based on the following evaluation criteria. The average score for each panelist was calculated, and the evaluation results were as follows: an average of 4.6 points or higher was given an "A grade," 3.6 points or higher but less than 4.6 points was a "B grade," 2.6 points or higher but less than 3.6 points was a "C grade," 1.6 points or higher but less than 2.6 points was a "D grade," and 1 point or higher but less than 1.6 points was an "E grade." The results are shown in Tables 1 to 3. (Evaluation Criteria) 5 points: It has weight, gives a strong impression that the damage has been well cared for, and does not give the impression of being unnaturally crushed or dented as a result of being too heavy. 4 points: It has weight, gives the impression that the damage has been well cared for, and does not appear to have an unnatural appearance such as being crushed as a result of being too heavy. 3 points: It has a slight weight, gives the impression that some damage has been taken care of, and does not give the impression of an unnatural appearance such as crushing that can result from being too heavy. Points 2: It lacks weight and doesn't give the impression that the damage has been properly addressed, or it appears unnatural, such as being crushed due to being too heavy. 1 point: It lacks weight and gives no impression of damage being properly cared for, or it gives a strong impression of having an unnatural appearance such as being crushed due to being too heavy.
