供することにある。DISCLOSURE OF INVENTION Problems to be Solved by the Invention In a hair dye containing an acid dye, the stronger the acidity, the higher the hair dyeing effect. However, there were few thickeners that could withstand strong acidity, and they were unstable over time. Xanthan gum, which is stable only under strong acidity, has a thixotropic hair dye finish,
It lacked usability. Further, a hair dye hardened with a higher alcohol is stable even under strong acidity, but has a drawback that the hair dyeing effect is slightly deteriorated due to the large amount of oil. Therefore, an object of the present invention is to provide a hair dye having excellent hair dyeing properties and high stability.

%, Preferably 2.0 to 10.0% by weight. When the content is less than 2.0% by weight, sufficient hair dyeing properties cannot be obtained, and when it is 15.0% by weight or more, there is a problem in safety, and no effect is enhanced with increasing content. The hair dye of the present invention has a pH of 1.0 to 3.0, preferably 1.0.
Adjust to ~ 2.5. This is because at a pH of 3.0 or higher, a sufficient hair dyeing effect cannot be obtained. The pH adjustment may be performed using, for example, an organic acid such as lactic acid, tartaric acid, glycolic acid, citric acid, oxalic acid, or an inorganic acid such as phosphoric acid or hydrochloric acid. Further, the hair dye of the present invention contains lower alcohols, polyhydric alcohols, preservatives, chelating agents, ultraviolet absorbers, fragrances, etc. in addition to the above-mentioned essential components as long as the stability of the system and the pH value are not impaired. It can be blended appropriately. To carry out dyeing of keratinous fibers such as hair using the hair dye of the present invention,
For example, the hair dye of the present invention may be applied to keratinous fibers at 15 to 50 ° C., after a working time of about 1 to 30 minutes, the keratinous fibers may be washed and dried.
