When the viscosity is at least the lower limit, the first agent and the hair treatment composition can be mixed more effectively. Furthermore, it becomes easier to adjust the viscosity of the mixed agent within a suitable range, further improving adhesion and applicability to hair. When the viscosity is at most the upper limit, the first agent and the hair treatment composition can be mixed more effectively.

[0104] The viscosity of the hair treatment composition at 25°C is measured using a viscometer with a No. 4 rotor at a rotation speed of 12 rpm for 1 minute. The viscometer may be a TV-25 model viscometer manufactured by Toki Sangyo Co., Ltd.

[0106] The hair treatment composition can be produced by a known method for producing a hair treatment composition (second agent). Examples of the method for producing the hair treatment composition include a method in which the components are stirred and homogenized using a paddle mixer or the like.

[0112] (oxidation dyes) The first agent contains or does not contain an oxidative dye. When the first agent contains an oxidative dye, a multi-component hair treatment comprising at least the first agent and the hair treatment composition (second agent) is an oxidative hair dye. When the first agent does not contain an oxidative dye, a multi-component hair treatment comprising at least the first agent and the hair treatment composition (second agent) is a hair bleach or hair bleaching agent. The term "oxidative dye" refers to both an oxidative dye precursor that develops color through its own oxidative polymerization and a coupler that develops various colors through a reaction with the oxidative dye precursor. Only one type of oxidative dye may be used, or two or more types may be used.

[0113] Examples of the oxidation dye precursor include phenylenediamine compounds, aminophenol compounds, diaminopyridine compounds, and salts thereof, such as hydrochlorides and sulfates.

[0119] (reducing agent) When the first agent contains an oxidative dye, it is preferable that the first agent contains a reducing agent. By containing a reducing agent in the first agent, color development of the oxidative dye is effectively suppressed when the first agent is exposed to the atmosphere. Only one type of reducing agent may be used, or two or more types may be used.

When the content of the reducing agent is equal to or more than the above lower limit and equal to or less than the above upper limit, color development of the oxidation dye when the first agent is exposed to the atmosphere can be more effectively suppressed.

[0122] (water) The first agent contains or does not contain water, and the water is preferably purified water.

[0123] The content of water in the first agent can be adjusted appropriately depending on the type of container that stores the first agent and the desired properties of the first agent. When the first agent is a powdered first agent, it is preferable that the first agent does not contain water.

[0124] The first agent may contain other components in addition to the oxidative dye, alkaline agent, reducing agent, and water, provided that the effects of the present invention are not impaired. Examples of such other components include those described in the section above regarding the "Hair Treatment Composition (Second Agent)."

[0125] (Other details of the first agent) The form of the first agent is not particularly limited, and may be in powder form, liquid form, gel form, cream form, or any other form.

[0126] The first agent is preferably in powder form. When the powdered first agent is mixed with a conventional second agent, poor mixing of the first and second agents occurs, abnormal heat generation occurs, and adhesion to hair is reduced, leading to dripping. In contrast, the present invention uses a hair treatment composition (second agent) containing components (A1) to (A3), which allows the first and second agents to be mixed well, reduces abnormal heat generation, and improves adhesion to hair.

[0127] The first agent can be stored and used in a container, such as a plastic container, an aluminum tube container, or a pouch container.

[0128] As a method for producing the first agent, a known method for producing the first agent can be adopted.

[0129] [Hair treatment agent] The hair treatment agent of the present invention comprises at least the first agent and the second agent.

[0135] The ratio of the viscosity of the mixed agent at 25°C to the viscosity of the second agent (the hair treatment composition) at 25°C (viscosity of the mixed agent at 25°C / viscosity of the second agent at 25°C) is preferably 1.5 or more, more preferably 2.0 or more, and preferably 10.0 or less, more preferably 9.0 or less. When the ratio (viscosity of the mixed agent at 25°C / viscosity of the second agent at 25°C) is at least the above lower limit and at most the above upper limit, the adhesion and application to hair can be further improved.

[0136] The viscosity of the mixture at 25°C is measured using a viscometer with a No. 4 rotor at a rotation speed of 12 rpm for 1 minute. The viscometer may be a TV-25 viscometer manufactured by Toki Sangyo Co., Ltd.

[0137] The pH of the mixture is preferably 8 or higher, more preferably 9 or higher, and preferably 13 or lower, more preferably 12 or lower. When the pH is equal to or higher than the lower limit, the viscosity of the mixture at 25°C can be easily adjusted to fall within the preferred range, further enhancing adhesion to hair. When the pH is equal to or lower than the upper limit, skin irritation is reduced.

[0138] The mixing ratio when mixing the first agent and the second agent is not particularly limited. From the viewpoint of mixing the first agent and the second agent well, it is preferable to mix the second agent with 1 g of the first agent at preferably 0.5 g or more, more preferably 1 g or more, preferably 5 g or less, and more preferably 3 g or less.
