Description

The present invention relates to a hair treatment agent set and a hair treatment composition. More specifically, the present invention relates to a hair treatment agent set and a hair treatment composition suitable for improving the frizziness of hair.

Hair is routinely damaged by shampooing with cleansers such as shampoos and drying with hair dryers. In addition, in recent years, with the diversification of hairstyles, chemical treatments such as dyeing, bleaching, and perming have become popular. These chemical treatments also damage the hair. Furthermore, it is known that the texture of hair changes with aging.

Damage to hair due to chemical treatments such as dyeing and bleaching, damage to hair due to physical treatments such as heat and friction, and changes in hair texture due to aging cause hair to have an undulating shape. The increase in such frizzy hair causes the hair to become dry and spread. In addition, the increase in frizzy hair deteriorates the texture of the hair, such as the luster of the entire hair, the feel of the hair, and the manageability of the hair.

Hair treatment agents containing specific compounds have been proposed to address the above problems. For example, Patent Literature 1 describes that hair frizziness is improved by hardening the hair using a hair treatment composition containing an aspartame component.

In Patent Document 2, hair frizziness is improved by using a hair cosmetic in which a first agent containing a specific cationized polymer and a second agent containing a specific phosphorylcholine group-containing polymer are combined. It is stated that

The techniques described in Patent Literatures 1 and 2 harden the hair by causing a hair treatment agent to act on the surface of the hair in order to suppress waviness of the hair. According to the hair compositions described in Patent Documents 1 and 2, the hair tends to become stiff. In addition, the effect of the hair treatment agent adhering to the surface of the hair is poorly sustained.

An object of the present invention is to provide a hair treatment agent set and a hair treatment composition that are suitable for reducing frizziness of hair.
