As is clear from Table 9, when a high-set gel in an irreversible thermal gelation state is used, the set holding power is not bad, but the hair styling ability is in another gelation state. It became clear that it was inferior to that of. In particular, hairdressing cosmetics containing a powder dispersion in an ungelled state or a dissolved neutralized gelled substance which is considered to be in a gelling state different from thermal gelation exhibited particularly excellent effects. From this, it is presumed that the gelling state of the polymer substance is closely related to the hair styling power and the set holding power.

The compositions of Test Examples 32 and 33 were applied to fully dried hair after shampooing and wet hair to such an extent that water drops were gently wiped after shampooing, and then dried with 85 ° C. warm air. Was. Table 12 shows the hair styling power and the set holding power in this case. As a control for hair styling control, the same formulation as in Test Example 33 was used except that the non-gelled curdlan powder was replaced with carboxymethyl cellulose.

As can be seen from Table 13, when the powder was not blended (Test Example 32), the hair was too light during blowing, so that the hair was not easily caught by the brush and hard to blow. On the other hand, when the powder was blended, there was an appropriate tension at the time of blowing, and the powder was easily caught on the brush, and it became easy to blow. However, in the case of a powder having a pigment grade size, the lightness and feel after finishing are poor, so that it became clear that a fine powder was preferable as the powder.
