Description

[Technical Field]

[0001] The present invention relates to a hair dye composition used for dyeing hair. [Background technology]

[0002] Hair dye compositions containing direct dyes are known as hair dye compositions that cause less damage to hair and scalp. In hair dye compositions containing direct dyes, it is difficult to achieve a desired color with a single direct dye, so two or more direct dyes are usually used.

[0003] Among direct dyes, basic dyes are convenient because they can dye hair without involving an oxidation reaction, and are dyes with excellent hair dyeing properties. Patent Document 1 listed below discloses a hair dye composition containing a specific basic dye. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Japanese Patent Application Laid-Open No. 2012-246229 Summary of the Invention [Problem to be solved by the invention]

[0005] The hair dyeing effect of basic dyes is achieved by the positively charged basic dye binding to the negatively charged parts of the hair. Damaged parts of the hair have a higher negative charge than non-damaged parts, so the basic dye is more likely to bind to damaged parts than non-damaged parts of the hair.

[0006] Hair may be repeatedly dyed using a hair dye composition. For example, a color rinse (also called a color treatment or color conditioner) may be used repeatedly every day or about two to three times a week, with rinsing. Repeated dyeing of hair makes it easier for the dye to adhere to the hair.

[0007] The present inventors have prepared a hair dye composition containing Basic Blue 77 as an essential component and Basic Blue 75 as an optional component in order to enhance hair dyeing power, and have found that when hair is repeatedly dyed with this hair dye composition, the problem of hair hue changing occurs, and that this problem occurs more significantly in damaged areas of the hair. The following is thought to be the cause of this.

[0008] Basic Blue 77 and Basic Blue 75 are basic blues that are particularly likely to bind to damaged areas of hair during dyeing and are likely to remain in the hair after rinsing (i.e., are less likely to fade). Therefore, when the basic blue is used in combination with a basic dye of another color, differences tend to occur in the degree of binding to and remaining on the hair between the basic blue and the basic dye of another color. For this reason, when hair is repeatedly dyed with a hair dye composition containing the basic blue and a basic dye of another color (especially when repeated dyeing is performed with rinsing), the hue of the hair changes due to differences in the degree of binding to and remaining on the hair.

[0009] The hair dyeing effect of dyes other than basic dyes, such as nonionic dyes, is achieved by the penetration of the dye into the hair. Therefore, dyes other than basic dyes are less likely to exhibit the above-mentioned differences in the degree of binding to hair and the degree of remaining in hair. Therefore, the problem of hair color change is mainly caused by the basic dye contained in the hair dye composition.

[0010] An object of the present invention is to provide a hair dye composition that can suppress changes in hair color. [Means for solving the problem]

Because the hair dye composition of the present invention has the above-mentioned configuration, it can suppress changes in hair hue. DETAILED DESCRIPTION OF THE INVENTION

[0030] The present invention will be described in detail below.

[0031] The hair dye composition of the present invention contains "Basic Blue 77, or Basic Blue 77 and Basic Blue 75," "Basic Brown 16," and "Basic Purple 2."

[0032] In this specification, the above-mentioned "Basic Blue 77, or Basic Blue 77 and Basic Blue 75" may be referred to as "component (A)".

[0033] In this specification, the above-mentioned "Basic Tea 16" may be referred to as "Component (B)."

[0034] In this specification, the above-mentioned "Basic Purple 2" may be referred to as "Component (C)."

[0035] Therefore, the hair dye composition of the present invention contains component (A), component (B) and component (C).

[0036] In the hair dye composition of the present invention, the mass ratio of the content of component (B) to the content of component (A) (content of component (B) / content of component (A)) is 1.3 or more and 6.0 or less, and the mass ratio of the content of component (C) to the content of component (A) (content of component (C) / content of component (A)) is 0.04 or more and 0.3 or less.

[0037] The hair dye composition of the present invention has the above-mentioned features, and therefore can suppress changes in hair color.

[0038] When hair is repeatedly dyed using a conventional hair dye composition containing component (A), the hue may clearly vary depending on the level of damage to the hair, i.e., depending on the region of the hair. In particular, when hair is repeatedly dyed using a conventional hair dye composition containing component (A) with rinsing, the hue is likely to vary depending on the region of the hair. In contrast, the hair dye composition of the present invention, despite containing component (A), can suppress changes in hair hue even when hair is repeatedly dyed, even when hair is repeatedly dyed with rinsing. The hair dye composition of the present invention can particularly suppress changes in hue in damaged regions of hair, thereby reducing the difference in hue between damaged and undamaged regions of hair. Therefore, the hair dye composition of the present invention can dye hair to a desired hue even when hair is repeatedly dyed, even when hair is repeatedly dyed with rinsing.

[0039] Furthermore, since the hair dye composition of the present invention contains component (A), it is possible to enhance the dyeing power of hair.

[0160] Step (5): Steps (2) to (4) were repeated a total of three times to repeatedly dye the test hair bundle.
