The numerical value in parentheses of the compound name POE is E.I. O. Indicates the number of moles added.

Then, the first agent, the second agent, and the third agent were mixed at a mass ratio of 1: 2: 0.3 to prepare the oxidative hair dye of each example. The obtained oxidative hair dye was applied to a hair bundle of black hair and white hair (manufactured by 10 cm Burax Co., Ltd.) (hereinafter, simply referred to as a hair bundle) using a brush, and left at 30 ° C. for 30 minutes. Next, after rinsing the oxidative hair dye adhering to the hair bundle with water, shampoo (a bigen treatment shampoo manufactured by Hoyu Co., Ltd. as a shampoo composition) is applied to the hair bundle twice, and rinse (Hoyu as a rinse composition). The company's Bigen Treatment Rinse) was applied once. The shampoo composition and the rinse composition are each rinsed with water after each treatment. Subsequently, the hair bundle was dried with warm air and then left for one day. The hair bundles after the hair dyeing treatment were evaluated for fading resistance and color vividness according to the methods shown below.

(Fade resistance)
The hair bundle that had been dyed was washed 10 times with a 10 mass% sodium laureth sulfate aqueous solution. The color tone of the hair bundle after the washing treatment was visually observed by five panelists under a standard light source, and the fading resistance was judged according to the following criteria as compared with the hair bundle not subjected to the washing treatment. The fading resistance is excellent (5 points), good (4 points), acceptable (3 points), slightly defective (2 points) and defective (1 point), and the average value for each panelist's scoring result. The average value is 4.6 points or more as "excellent: 5", 3.6 points or more and less than 4.6 points as "good: 4", and 2.6 points or more and less than 3.6 points as "possible:". 3 ”, 1.6 points or more and less than 2.6 points were regarded as“ slightly defective: 2 ”, and less than 1.6 points were evaluated as“ defective: 1 ”as evaluation results. The results are shown in the table below.

(Color vividness)
Five panelists visually observed the vividness of the color of the hair bundle after dyeing under a standard light source, and judged it according to the following criteria. The vividness of the color of the hair bundle is scored on a scale of 5: excellent (5 points), good (4 points), acceptable (3 points), slightly defective (2 points) and defective (1 point), and each panelist scores. Calculate the average value of the results, and if the average value is 4.6 points or more, it is "excellent: 5", if it is 3.6 points or more and less than 4.6 points, it is "good: 4", and if it is 2.6 points or more and less than 3.6 points. Was "OK: 3", 1.6 points or more and less than 2.6 points was "Slightly defective: 2", and less than 1.6 points was "Defective: 1". The results are shown in the table below.
