FIG. 1 shows the principle of color development when dyeing hair using indigo.
In FIG. 1, (1) indican (water-soluble), a glycoside mainly contained in leaves of indigo, is hydrolyzed by an enzyme (β-glucosidase) contained in the same plant (2). ) Produces indoxyl (water soluble). In air, this (2) indoxyl is oxidatively associated with two molecules, and becomes (3) indigo (water-insoluble) to develop color.

The hair dye according to one embodiment of the present invention is a hair dye containing, as a main hair dye material, fresh indigo leaves or juice of indigo fresh leaves. The hair dye of the present invention containing mainly indigo fresh leaves is contained as long as the indigo leaves are not crushed, beaten or rubbed, etc. (1) Indican is stable, and the enzyme (β-glucosidase) is used. Not subject to hydrolysis. When used to dye hair, the indigo leaves are first crushed, beaten, or rubbed in the presence of water, and then uniformly applied to the hair.
