[0019] Therefore, the present invention relates to a hair treatment agent or a fiber treatment agent for hair accessories that can maintain a non-dry feeling or non-tangling feeling in a wet state even after the treated hair or fiber for hair accessories is repeatedly washed. In addition, the present invention relates to a hair treatment agent or a fiber treatment agent for hair accessories that is also good in feel during use (non-sticky) and formulation stability.

[0020] The present inventors have found that by using two specific cationic surfactants, a higher alcohol, and two specific silicones in a rinse-off hair cosmetic used after shampooing, such as a hair treatment agent or a fiber treatment agent for hair accessories, preferably a hair conditioner or a hair rinse, the treated hair or fibers for hair accessories can be kept free of dryness or tangles in a wet state. In addition, the inventors have found that the hair treatment agent or the fiber treatment agent for hair accessories also has a good feel during use (non-sticky) and formulation stability.

[0021] The hair treatment agent or fiber treatment agent for hair ornament products of the present invention can maintain a feeling of no dryness or tangling in a wet state even after the treated hair or fiber for hair ornament products is repeatedly washed, and the hair treatment agent or fiber treatment agent for hair ornament products is also excellent in feeling during use (no stickiness) and formulation stability.

[0244] 2. Apply 1 mL of each of the conditioners shown in Tables 5 to 6, rub with hands, leave for 30 seconds, and then rinse for 15 seconds.

[0245] 3. After drying with a towel or hair dryer, rub 1 mL of the common shampoo shown in Table 1 on the front and back 20 times each, wash for 30 seconds, and then rinse for 15 seconds. Then, blend 1 mL of the common cleaning agent shown in Table 4 for 30 seconds and rinse for 15 seconds.

[0246] 4. After completely detangling the hair with a comb, adjust the water content to 15 g.

[0247] 5. The dynamic combing force method (Suzuki et al.; J. Soc. Cosmet. Chem. Japan. Vol. 27, No. 1, P11-13, 1993) was used to measure the combing force when the hair is combed 30 times at a constant speed (once per second), and the average of the 30 measured values ​​(maximum value) was calculated as the evaluation index of the sustainability of the conditioning effect. The smaller the combing force value, the better the combing property and the smoother the hair.

[0248] (Method for evaluating the sustainability of conditioning effects on wet hair after 3 washes)

[0249] The combing force was measured and evaluated in the same manner as in the above-mentioned "Method for evaluating the sustainability of the conditioning effect on wet hair immediately after treatment" except that step 3. of the evaluation procedure was repeated a total of three times.
