DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention repairs damage caused by hair dyeing by applying it to hair which has been subjected to hair dyeing treatment.
In addition, the present invention relates to a hair dye post-treatment agent capable of preventing accumulation of damage beforehand and improving touch and color durability.

[0002]

2. Description of the Related Art At present, from gray hair dyeing for hiding gray hair,
Various hair colors using oxidation dyes, such as bleach colors for brightening black hair, are widely used. However, there is a problem that the hair may be damaged by the hair dyeing treatment, the touch of the hair may be deteriorated, and the color tone may be changed due to detachment of the dye. Also, while repeating the hair dyeing operation,
Since damage to the hair is accumulated and does not easily return to the original state, there is also a problem that the feel of the hair deteriorates and the change in color tone increases.

[0003] Therefore, by acid treatment after hair dyeing,
Treatment agents that return the pH from neutral to near neutral have been proposed, but sharply lower the pH, causing convergence of the hair and decomposition of the dye, resulting in rough hair and a change in color tone. It had not been resolved.

[0004]

SUMMARY OF THE INVENTION The present invention repairs hair damage caused by hair dyeing, prevents the accumulation of the damage, and retains color after hair dyeing without causing discoloration due to hair convergence or dye decomposition. It is an object of the present invention to provide a hair dyeing post-treatment agent which can improve the finish and improve the finish such as the feel of hair.

[0005]

Means for Solving the Problems The present inventors have prepared (A) a pH comprising an organic acid and / or an organic acid salt and an alkali agent.
