Summary of the Invention

Problems to be Solved by the Invention

[0004] Hair styling using a hair styling agent composition is usually performed through the following steps: 1) spreading the hair styling agent composition to some extent in the palm, 2) applying the hair styling agent composition to the hair, and 3) styling the hair into a desired hairstyle while spreading the hair styling agent composition on the hair.

[0005] However, a conventional hair styling agent composition containing a wax that is solid at 25°C may have poor spreadability of the hair styling agent composition on the hair during styling and may be inferior in usability. For example, in a conventional hair styling agent composition containing a wax that is solid at 25°C, a resistance feeling such as being caught by a finger may occur during styling, making it difficult to style the hair.

[0006] Further, when the content of the wax that is solid at 25°C is reduced in order to improve the coatability, the hair styling retention decreases.

[0007] An object of the present invention is to provide a hair styling agent composition containing a wax that is solid at 25°C, which can improve elongation on hair during hair styling and further enhance the hair styling retention force.
