Description

  The present invention relates to an aerosol spray hairdressing agent in which a hairdressing agent stock solution is sprayed in the form of a mist.

  In forming the hair style, the curling iron may be used to give the hair a curled shape. Moreover, in order to maintain the shape given to hair favorably, it is common to use a hair styling agent before or after giving a curled shape. Among the hair styling agents used in such cases, aerosol spray hair styling agents are low in moisture and tend to keep the hair in a light curl shape.

  By the way, it is common that the aerosol spray hairdressing agent is blended with a set resin for maintaining the hair style. However, with a hair styling agent containing a set resin, the set resin hardens immediately after being applied to the hair, and once the style is disturbed, the hair is restyled by applying a hand comb or comb, etc. It is difficult.

  For these reasons, studies have been made to increase the re-styling properties of aerosol spray hair styling agents. For example, Patent Document 1 describes an aerosol spray hairdressing agent containing a specific higher fatty acid and a polyhydric alcohol together with a film-forming polymer corresponding to a set resin.
