The formulation components shown in Tables 1 to 3 below were blended (the blending unit was mass%) to prepare an aerosol spray hair styling composition (stock solution) having the composition shown in Tables 1 to 3 below. The obtained aerosol spray hairdressing composition (stock solution) was filled in an aerosol spray container (volume: 95 mL). Then, after clinching the aerosol valve into the aerosol spray container, the propellant shown in Tables 1 to 3 below was filled from the stem, and a button suitable for the stem was attached to prepare an aerosol spray hair styling agent.

(Evaluation)
Five expert panels made the following evaluations.

(Test Example 1: Compatibility)
Each stock solution (aerosol spray hair styling composition) and each propellant thus obtained were put in a pressure resistant bottle (“Aerosol test bottle” manufactured by Tokyo Kogyo Co., Ltd., capacity: 100 mL), and the total amount of the stock solution and the propellant was 30 g. (The mass ratio of the undiluted solution and the propellant is as shown in Tables 1 to 3). The compatibility was evaluated according to the following criteria. If the compatibility was evaluated poorly, Test Examples 2 to 6 were not performed.

<Comparison evaluation criteria>
◯ (good): no turbidity or precipitation x (bad): turbidity or precipitation

(Test Example 2: Dispersibility)
Each stock solution (aerosol spray hair styling composition) and each propellant thus obtained were put in a pressure resistant bottle (“Aerosol test bottle” manufactured by Tokyo Kogyo Co., Ltd., capacity: 100 mL), and the total amount of the stock solution and the propellant was 30 g. As described above, the mass ratio of the undiluted solution and the propellant is as shown in Tables 1 to 3 and the mixture was left standing for 24 hours. After standing still, the mixture was inverted and stirred, and the number of inversions until complete dispersion was obtained. The dispersibility was evaluated according to the following criteria. In addition, Comparative Example 3 was not evaluated because silica was not added to the stock solution. If the dispersibility was evaluated poorly, Test Examples 3 to 6 were not performed.

<Dispersion evaluation criteria>
◯ (Good): Completely disperse after 1 to 2 times of reversal stirring Δ (Slightly bad): Completely disperse after 3 to 5 times of reversal stirring × (Poor): Six times or more reversal stirring until completely dispersed is necessary

(Test Example 3: Hair styling power during hair styling)
Five specialist panels sprayed each aerosol spray hairdressing agent onto the hair of a short hair wig (lesson mannequin: made by Eucalyptus Japan) evenly from a position of 15 cm for 3 seconds, and hair was directed upward from the root of the hair. I got up and styled. The hair styling power during hair styling was evaluated according to the following criteria.

<Evaluation criteria for hair styling during hair styling>
○ ○ (quite good): Shaped hair is kept clear and easy to arrange ○ (Good): Shaped hair is kept sharp but arrangement power is slightly inferior △ (Slightly poor) ): Part of hair does not stand up x (bad): Hair does not stand up

(Test Example 4: Finish after hair styling)
After the evaluation of Test Example 3 (hair styling power during hair styling) described above, 5 expert panels evaluated whether the wig's hair had a matte natural finish according to the following criteria.

<Evaluation criteria of finish after hair styling>
○ ○ (quite good): Matte feeling, natural finish without unnatural hair bundles ○ (Good): Matte feeling, slightly hair bundle feeling but natural finish △ (Slightly (Poor): There is gloss or an unnatural hair bundle is formed. × (Bad): There is a gloss feeling and an unnatural hair bundle is formed.

(Test Example 5: Hair-holding power)
After the evaluation of Test Example 4 (finishing after hair styling), the wig after hair styling was allowed to stand in a thermo-hygrostat (35 ° C., 80% RH) for 8 hours. After standing, five expert panels observed the hair of the wig and evaluated the hair styling retention power according to the following criteria.

<Evaluation criteria for hair styling retention>
○ ○ (quite good): Maintains the condition at the time of initial hair styling ○ (Good): Slightly drips from the condition at the time of initial hair styling △ (Slightly bad): Initial hair styling for more than half of the hair Dripping from the state at the time x (poor): Almost all hair dripping from the state at the time of initial hair styling

(Test Example 6: Hair restylability)
After the evaluation of the above-mentioned Test Example 5 (hair-holding power), the shape of the hair of the wig that had been hair-dressed was broken. After that, the hair was raised from the root of the hair upward, and the hair was re-styled. Five professional panels evaluated the hair restyling properties according to the following criteria.

<Evaluation Criteria for Hair Restoration>
○ ○ (quite good): Shaped hair is kept clear and easy to arrange ○ (Good): Shaped hair is kept sharp but arrangement power is slightly inferior △ (Slightly poor) ): Part of hair does not stand up x (bad): Hair does not stand up

  The composition and results are shown in Tables 1 to 3 below.
