First, a mixture in which a first agent and a second agent of an oxidative hair dye were mixed at a mass ratio of 1: 1 was applied to the hair bundle. After the hair bundle was allowed to stand for a predetermined time, the hair dyeing was completed by washing away the oxidative hair dye with warm water. This dyed hair bundle was used as a test hair bundle sample. The test hair bundle sample is in a wet state without being dried.

＜ヘアトリートメント剤の適用＞
表１に示される各例のヘアトリートメント剤を試験用の毛束サンプルに適用した。まず、ヘアトリートメント剤の第１剤、第２剤、及び第３剤を順に前記毛束サンプルに重ねて塗布した後、ヘアトリートメント剤を温水で洗い流した。次に、毛束サンプルに市販のシャンプー及び市販のコンディショナーを常法に従って適用した後にドライヤーを用いて乾燥させた。

<Application of hair treatment agent>
The hair treatment agent of each example shown in Table 1 was applied to a test hair bundle sample. First, the first agent, the second agent, and the third agent of the hair treatment agent were sequentially applied to the hair bundle sample, and then the hair treatment agent was washed away with warm water. Next, a commercially available shampoo and a commercially available conditioner were applied to the hair bundle sample according to a conventional method and then dried using a dryer.

<Good fingering>
20 panelists compared the fingering of the hair bundle sample to which the hair treatment agent of each example was applied and the fingering of the hair bundle sample for comparison. The hair bundle sample for comparison was prepared by applying a commercially available shampoo and a commercially available conditioner according to a conventional method without applying a hair treatment agent to the above-described hair bundle sample for testing and then drying it using a dryer. It is.

  For hair bundle samples to which the hair treatment agent of each example is applied, when the number of panelists who answered that finger passage is good for the comparative hair bundle samples is 17 or more, “5”, “13” for 13 to 16 people, “3” for 9 to 12 people, “2” for 5 to 8 people, and 4 or less. Gave a five-point rating of “1”. The results of this evaluation are shown in the “Fingering Good” column of Table 1.

<Permanent sustainability>
A hair bundle sample for evaluation used for evaluation of sustainability of goodness of finger was prepared. The hair bundle sample for evaluation was obtained by immersing the hair bundle sample obtained in the same manner as in the above <application of hair treatment agent> in a 1% by mass aqueous solution of sodium lauryl sulfate at 50 ° C. for 6 minutes (repeating shampoo treatment). It was washed with water after performing an acceleration test). Next, a commercially available shampoo and a commercially available conditioner were applied to the hair bundle sample according to a conventional method and then dried using a dryer.

In addition to the hair bundle sample for evaluation, the hair bundle sample obtained in <Application of hair treatment agent> was prepared as a reference hair bundle sample.
For each example, 20 panelists compared the fingering of the reference hair bundle sample and the fingering of the evaluation hair bundle sample. A five-point evaluation was made based on the number of panelists who answered that there was almost no difference between the two fingers, that is, the goodness of the fingers was maintained. The relationship between the number of panelists and the five-level evaluation is the same as the above <Goodness of finger>. The results of this evaluation are shown in the column “Sustainability of good fingering” in Table 1.

<Inhibiting effect of water swellability>
The test hair bundle sample was dried with a dryer. The hair bundle sample was observed with an optical microscope, and the diameter (R1) of the dried hair was measured. Next, the hair whose diameter (R1) was measured was swollen with water and observed with an optical microscope, and the diameter (R2) was measured.

On the other hand, for the hair bundle sample obtained in <Application of hair treatment agent>, the diameter of dry hair (R3) and the diameter of hair swollen with water (R4) were also measured.
The diameters (R1) to (R4) thus measured were substituted into the following formula to calculate the water swelling suppression ratio.

Water swelling suppression ratio (%) = 100-100 × [(R4 / R3) ² / (R2 / R1) ² ]
As shown in the above formula, the water swellability suppression ratio is a value calculated on the basis of a change in the cross-sectional area of the hair from a dry state to a swollen state, assuming that the cross section of the hair is a perfect circle. It is. The higher the water swellability suppression ratio, the closer the hair is to the state before being damaged by dyeing, and thus the natural elasticity of the hair can be easily obtained.

  For each example, “5” when the water swelling suppression ratio is 15% or more, “4” when 11% or more and less than 15%, and 7% or more and less than 11%. The evaluation was made on a five-point scale, with “3” being 3% or more and less than 7%, “2” being less than 3% and “1” being less than 3%. The result of this evaluation is shown in the column “Suppression effect of water swellability” in Table 1.

<Discoloration suppression effect>
20 panelists compared the color tone of the hair bundle sample to which the hair treatment agent of each example was applied and the color tone of the comparative hair bundle sample. The hair bundle sample for comparison was prepared by applying a commercially available shampoo and a commercially available treatment according to a conventional method without applying a hair treatment agent to the above-described hair bundle sample for testing and then drying it using a dryer. It is.

  The hair bundle samples to which the hair treatment agent of each example was applied were rated on a five-point scale based on the number of panelists who reported that fading was suppressed more than the comparative hair bundle samples. The relationship between the number of panelists and the five-level evaluation is the same as the above <Goodness of finger>. The result of this evaluation is shown in the “fading suppression effect” column of Table 1.

<Durability of anti-fading effect>
A hair bundle sample for evaluation used for evaluating the sustainability of the fading inhibiting effect was prepared. The evaluation hair bundle sample is the same as the evaluation hair bundle sample used for evaluating the sustainability of goodness of fingers.

In addition to the hair bundle sample for evaluation, the hair bundle sample obtained in <Application of hair treatment agent> was prepared as a reference hair bundle sample.
For each example, 20 panelists compared the color tone of the standard hair bundle sample and the color tone of the evaluation hair bundle sample. Then, a five-point evaluation was made based on the number of panelists who answered that there was almost no difference in color tone between them, that is, that the fading suppression effect was sufficiently sustained. The relationship between the number of panelists and the five-level evaluation is the same as the above <Goodness of finger>. The results of this evaluation are shown in the “Persistence of fading suppression effect” column of Table 1.
