3. Thereafter, the hair bundle was taken out of the ion-exchanged water, and dried with a towel to remove moisture from the hair bundle.
4. The above operations 1 to 3 were performed once, and the hair bundle subjected to the single operation was produced as a hair sample for evaluation. In the evaluation described below, 1 g of the following conditioner for evaluation was applied to the hair bundle after towel drying, and the hair was thoroughly rinsed with ion-exchanged water and then washed with a towel to remove the entanglement of the hair. It was dried with a dryer for 3 minutes while adding operations. The prescription of the conditioner for evaluation is shown in Table 1 below.

(Evaluation of hair damage promotion degree (evaluation of stretched hair))
1. Five hairs were randomly picked up from the hair bundle of the evaluation hair sample subjected to the above-described treatment, and a 10 cm to 15 cm portion (hair length: 5 cm) was cut out from the hair tip with a razor. A mending tape (manufactured by Scotch) was attached to both ends of the cut hair at a position of 0.5 cm from above and below to form a fixing portion.
Then, the cut hair is gripped by the fixed portion and pulled in the axial direction of the hair at a pulling rate of 0.1 cm / sec and a stretching ratio of 25% (from 4 cm before stretching the hair in the portion where the tape is not attached to 5 cm before stretching). Stretched). The stretched hair was fixed on a slide glass with a two-part adhesive so as not to move, and used as a measurement sample.
2. Using the above measurement sample, measure the hair surface shape with a laser microscope (manufactured by KEYENCE, VK-8700) (measurement pitch: 0.1 μm), and measure the inclination (slide glass or mending) other than the hair origin that occurs in the sample preparation. Tape, masking tape, etc.) was corrected for surface inclination on software (3 points specified). Thereafter, an average height Rc value (JIS B0601: 2001) of a roughness curve element according to JIS was calculated. As a calculation method, a straight line having a length of 200 μm was drawn in the axial direction on the hair surface whose inclination was corrected earlier, and the Rc value on the straight line was calculated by software. This operation was performed a total of five times on a randomly selected hair surface, and the average value was obtained.
It indicates that the larger the Rc value (μm), the rougher the surface shape, that is, the more the cuticle peeling is promoted. The smaller this value, the more the cuticle peeling is suppressed. I have.
