DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an aerosol-type foam hair styling, and more particularly, to a hair styling which has good usability, is not uneven, and can be freely styled without firmly hardening the hair. And a foam-like hair styling material having excellent hair styling properties over time.

[0003]

However, the above-mentioned hair styling materials have a high base viscosity, and are often uneven when applied to hair. If the viscosity of the base is reduced to improve the usability, there are problems such as a sticky finish, a decrease in hair styling ability, and a break in the hairstyle over time. Furthermore, since hair cream and hair milk are emulsified products, the oil content in the base sometimes makes the finish of the hair greasy, and sometimes the hands become sticky when used. Therefore,
It has been desired to develop a hair styling material that is easy to spread on hair, has good usability, can be naturally styled without hardening the hair, and has excellent hair styling properties over time.

If it is a foam-shaped hairdressing composition in which the undiluted solution and the propellant are combined at a specific mixing ratio, it becomes a good foam, without unevenness when applied to hair, and has good usability. In addition, the present inventors have found that a foamy hair styling material which can be freely styled without firmly hardening the hair and has excellent hair styling properties over time can be obtained, and the present invention has been completed based on this finding.

That is, the present invention provides the following components (A) to
