Description

Technical Field

[0001] The present invention relates to a hair cosmetic applied to hair after bleaching treatment or hair dyeing treatment with an oxidative hair dye or a bleaching agent, and particularly relates to a hair cosmetic composition having good spreadability, softness of hair, and a sense of hair cohesion, and no stickiness of hair.

Background Art

[0002] In recent years, due to the influence of chemical treatments such as oxidative hair dyes and bleaching agents, and physical treatments such as blow drying, hair has a tendency to become frizzy and lack cohesion. For such hair, various hair cosmetics have been developed to obtain a cohesion effect and a smooth feel. Generally, there are hair cosmetics that can be rinsed off, such as hair rinses, hair treatments, hair packs, and hair masks, and hair cosmetics that cannot be rinsed off, such as hair oils, hair milks, hair creams, and hair mists. In addition, hair cosmetics that cannot be rinsed off can reduce the damage caused by bleaching agents or oxidative hair dyes by being applied to hair after treatment with a bleaching agent or an oxidative hair dye.

[0003] It is known that such hair cosmetics that cannot be rinsed off are adjusted by adding a cationic surfactant, a higher alcohol, and an oily component in order to provide a conditioning effect. However, such hair cosmetics that cannot be rinsed off have problems such as feeling heavier and stickier rather than moist during the process from application to hair to drying and finishing.

[0004] For the purpose of solving the above problems, a hair cosmetic (Patent Document 1) characterized by containing a cationic surfactant, a higher alcohol having 14 to 22 carbon atoms, an alkyl ester of a branched fatty acid having 2 to 6 carbon atoms, and an α-olefin oligomer has been disclosed.
