EXAMPLES Hereinafter, the present invention will be described in more detail with reference to Examples, but it goes without saying that the present invention is not limited to only these Examples.

Example 1 A hair manicure of the present invention was prepared according to the following formulation. That is, the formulation components were stirred and solubilized at room temperature to obtain hair manicure. A hair dyeing test of white hair was performed using the hair manicure. After measuring the color of the gray hair bundle (10 g), the hair was treated with hemanicure, excess hair manicure was removed by shampoo, and the color was measured again to calculate the lightness difference (ΔL value) before and after the treatment. At this time, at the same time, Comparative Example 1 in which the polyhydric alcohol which is an essential component of the present invention was replaced with water, Comparative Example 1 in which glycerin was substituted, Comparative Example 2 in which propylene glycol was substituted, and Reference Example using conventional benzyl alcohol No. 1 was similarly prepared and tested similarly. Table 1 shows the results. This shows that the hair manicure of the present invention is excellent in hair dyeability.
This is because the penetration of the dye into the hair was promoted by the polyhydric alcohol having 4 or more carbon atoms having 0 or 1 ether bond, which is an essential component of the hair manicure of the present invention. In addition, it is apparent that a hair dye having better dyeability than benzyl alcohol can be obtained by such an action without using benzyl alcohol which is a conventional penetration enhancer. (The units of the components in the table represent parts by weight.)
