[0064] Performance verification:

[0065] 1. Fading test: The degree of hair fading was measured using an X-Rite colorimeter.

[0066] (1) The dyed hair was divided into groups (including examples and comparative examples), with 3 hair samples in each group. The hair was washed 10 times according to the experimental design, and the hair was blow-dried after each wash.

[0067] (2) Use an X-Rite colorimeter to measure the initial color (L*a*b* value) of each hair strand and calculate the average value as a baseline.

[0068] (3) Perform 10 washes (using commercially available ordinary shampoo) and conditioning (using the products of the examples and comparative examples) according to the experimental design, and blow-dry the hair after each wash.

[0069] (4) Measurement after fading (T1)

[0070] After 10 washes, the color change was measured using a colorimeter, and the L*\a*\b* values ​​were recorded. ΔE was then calculated. ab * (Color difference from the initial color T0).

[0071]

[0072] ΔE ab * The larger the value, the greater the color difference, indicating a higher degree of fading of the hair color;

[0073] ΔE ab * The smaller the value, the smaller the color difference, indicating a lower degree of hair color fading;

[0074] Where: L* (brightness), a* (redness / greenness), b* (yellowness / blueness).

[0075] Through the total color difference ΔE ab * The color retention ratio is calculated based on the change in , using the following formula:

[0076] Color protection rate % = [(ΔE) ab * Comparative Example - ΔE ab * Experimental example) / ΔE ab * [Comparative Example] × 100%

[0077] Table 2 shows the test results of color difference and color protection rate. It can be seen that, compared with the comparative example, the color protection rate of the color-fixing and color-protecting composition in the examples is significantly improved after treatment.

[0078] Table 2 Test Results of Color Difference and Color Protection Rate

[0080] 2. Static Electricity Test: The antistatic properties of the conditioner were tested using a Trek 520 series static electricity tester.

[0081] (1) Group hair strands of the same hair quality / length (example and comparative examples), apply the above examples and comparative examples samples evenly, let stand for 2 minutes, rinse with warm water, and blow dry (temperature: 22±2℃, humidity: 50±5%RH).

[0082] (2) Friction-induced static electricity: Rub the hair strand 10 times in one direction with a standard nylon comb (or wool cloth) (with consistent force).

[0083] (3) Electrostatic measurement: Point the Trek 520 probe at the hair bundle at a distance of 1cm (avoid contact), record the peak electrostatic voltage (unit: kV), repeat 3 times and take the average value.

[0084] Static electricity reduction rate % = [(static voltage of untreated hair - static voltage of treated hair) / static voltage of untreated hair] × 100%

[0085] Table 3 shows the test results of static voltage and static reduction rate. It can be seen that, compared with the comparative example, the static electricity was significantly reduced and the hair was smoother after treatment with the color-fixing and color-protecting composition of the example.
