[Family]
After spraying 0.3 g of each hair treatment composition of Examples and Comparative Examples on a dry hair bundle sample (30% human hair with a hair diameter of 60 to 100 μm) in a spray container and applying it by hand, It was made to dry enough using the dryer, without performing the washing-off process. Then, 3 g of an oxidative hair dye (trade name: Promaster G Curière Basic 8RB, manufactured by Hoyu Co., Ltd.) was uniformly applied to the hair bundle sample with a brush and left at 30 ° C. for 20 minutes. Thereafter, the hair bundle sample was washed with water, shampooed, and dried with a dryer. A specialized panelist evaluated the difference (familiarity) between the white hair and the black hair of the hair bundle sample after drying.

  The evaluation of “familiarity” is “8” when the difference in the degree of hair coloring between white hair and black hair is not felt at all, “7” when almost not felt, and “6” when the difference is felt slightly. “5” when it is slightly felt, “4” when it is slightly felt, “3” when it is felt, and “2” when it is felt a little The case was set to “1”.

  “Familiarity” here refers to the difference in the degree of hair coloring between white hair and black hair, which occurs when hair with mixed white and black hair is dyed. To improve the familiarity means to reduce the difference in the degree of hair coloring between white hair and black hair. That is, it means that the difference in the degree of dyeing between white hair and black hair is not felt.

[Low foaming during application]
Twenty professional panelists evaluated the foaming when each hair treatment composition of Examples and Comparative Examples was applied to the hair bundle sample. The evaluation is “5… very good” when the number of panelists evaluated as “less foaming during application” is 20 or more among the 20 panelists, and “4 ... “Excellent”, 9 to 12 people were “3... Good”, 5 to 8 people were “2 slightly bad”, and 4 or less were “1 bad”.

[No stickiness after drying]
Twenty professional panelists evaluated the ease of application (non-stickiness) when applying the hair dye composition after applying and drying each hair treatment composition of Examples and Comparative Examples to the hair bundle sample. . The evaluation is "7 ... very good" when the number of panelists evaluated as "no stickiness" among 18 panelists is 18 or more, "6 ... very good" when 15-17. In the case of 12 to 14 people, “5 ... excellent”, in the case of 9-11 people, “4 ... good”, in the case of 6-8 people “3… slightly bad”, in the case of 3-5 people “2” "Defective" and the case of 2 or less persons were designated as "1 ... very bad"

[Solubility]
(A) About the solubility in the hair treatment composition of the specific amino acid which is a component, after leaving each hair treatment composition of an Example and a comparative example for one day, the presence or absence of precipitation of (A) component It was evaluated by confirming. The evaluation was “◎” when no precipitation was observed after standing for 1 day and the sample was dissolved well. “◎” “O” means that a considerable amount of precipitate was observed after standing for 1 day, and the case where it could not be said that the precipitate was satisfactorily set was indicated by “Δ”.

[Evaluation results]
As shown in Tables 1 to 5, it can be seen that the hair treatment compositions of Examples 1 to 33 have a higher familiarity-improving effect than the hair treatment compositions of Comparative Examples 1 to 9. That is, it is possible to reduce the difference in the degree of white hair and black hair dyeing that occurs when hair with mixed white hair and black hair is dyed. It can also be seen that there is little foaming during application, no stickiness after drying, and high solubility.

  Moreover, as shown in Tables 1 and 2, it can be seen that the effect of improving the familiarity is enhanced by using histidine as the component (A). Moreover, when (A) component and (B) component are made into the same kind, and content of (B) component is made constant, by making content of (A) component into the range of 0.1-4 mass% It can be seen that the compatibility improvement effect and the solubility are increased.

  Moreover, as shown to the same table | surface, when (A) component and (B) component are made into the same kind, and content of (A) component is made constant, content of (B) component is 0.1-3 mass% It can be seen that the effect of improving the familiarity is enhanced by setting the amount within the range of (more preferably 0.5 to 3% by mass).

  Moreover, as shown in Table 3, in addition to the component (A) and the component (B), by further containing an anionic surfactant, while sufficiently suppressing foaming at the time of application and stickiness after drying, It can be seen that the familiar improvement effect is further enhanced.

  Moreover, as shown in Table 4, in addition to the components (A) and (B), surfactants other than anionic surfactants, that is, cationic surfactants, nonionic surfactants, amphoteric surfactants It can be seen that, even when it contains, a blending improvement effect can be sufficiently obtained while sufficiently suppressing foaming during coating and stickiness after drying.
