Description

TECHNICAL FIELD The present invention relates to a hair styling agent composition suitable for use as a hair styling agent for styling hair.

One of the hair styling performances required for hair styling compositions is the ability to maintain a styled hairstyle for a long period of time (hair style retention). A hair styling agent composition containing a wax that is solid at 25° C., as described in Patent Documents 1 and 2 below, can harden hair tresses after styling, and thus can enhance hair styling retention.

Hair styling using a hair styling composition is usually carried out by 1) stretching the hair styling composition on the palm of the hand to some extent, 2) applying the hair styling composition to the hair, and 3) applying the desired hair styling composition while spreading the hair styling composition on the hair. It is done through the process of styling the hair.
