Description

The present invention relates to a cleansing agent which is applied to dyed hair in which the release of the dye from the dyed hair is reduced, foaming and foam quality during washing are good, and the squeaky feeling upon washing off is suppressed. .

In recent years, the habit of hair coloring has permeated regardless of generation and gender, and along with this, permanent hair dyes such as oxidative hair dyes using oxidative dyes, hair manicures using direct dyes, and semi-permanent hair dyes such as color treatments. Various types of hair dyes such as a temporary colorant (temporary hair dye) such as a color spray for temporarily coloring hair are commercially available. As a user who enjoys these hair coloring, one of the demands is to have good color retention after hair dyeing. The discoloration of the dyed hair is caused by the structural change of the dye due to ultraviolet rays and the loss of color due to the removal of the dye from the hair by washing.

Until now, several methods have been proposed as methods for preventing discoloration after hair dyeing treatment. Hair-cleansing composition for hair treated with a specific surfactant (Patent Document 1), shampoo containing arginine or a salt thereof (Patent Document 2), highly polymerized silicone, ultraviolet absorber, acidic amino acids And a hair treatment agent (Patent Document 3) containing the same.
