• Comparative Examples 1, 2, 3, 4 and 6 are gel-like hair compositions composed of an anionic polymer alone. However, since no complex is present, it is difficult to feel the agent being easily broken and the usability is poor. .

The feeling of use was bad. Even when the ratio of the cationic polymer / anionic polymer and the viscosity are within the predetermined range, those having a large viscosity ratio as shown in Comparative Example 5 have a large amount of water carried in the complex and poor stability.
