Comparative Example 1, in which Step 1 was not carried out and which did not include the first composition, was inferior in "effect of improving hair strength" and "effect of improving hair firmness and elasticity." Also, in Comparative Example 2 where Step 2 was not carried out and the second composition was not provided, the "hair strength improvement effect", "hair stiffness improvement effect", and "hair smoothness improvement effect" were inferior. Similarly, in Comparative Example 3 where the order of use of Step 1 and Step 2 was reversed, the "hair strength improvement effect", "hair stiffness improvement effect", and "hair smoothness improvement effect" were inferior. Also, in Comparative Example 4 where the first composition did not contain arginine in Step 1, the "hair strength improvement effect" and "hair stiffness improvement effect" were inferior. In Comparative Example 5 where the pH of the first composition at 25°C was less than 8.0 in Step 1, the "hair strength improvement effect", "hair stiffness improvement effect", and "hair smoothness improvement effect" were inferior. In Comparative Example 6 where, in Step 1, instead of the first hair mist composition, the first lotion composition was provided, the "hair strength improvement effect" and "hair stiffness improvement effect" were inferior. In Comparative Example 7 where the second composition did not contain a multi-chain cationic surfactant in Step 2, the "hair strength improvement effect" and "hair stiffness improvement effect" were inferior, and in Comparative Example 8, the "hair strength improvement effect", "hair stiffness improvement effect", and "hair smoothness improvement effect" were inferior.
