The composition for hair according to another aspect of the present invention further comprises a side chain type cationic polymer in the hair composition.

Common hair compositions include linear, cationic polymers. These straight chain type cationic polymers form a complex of a strong cohesive force with the anionic surfactant in the hair composition and adsorb to the hair well. Since they have high adsorption power, they tend to accumulate in hair when repeatedly used.

On the other hand, the cationic polymer of the side chain type means that a specific group is introduced into the side chain of the linear type cationic polymer. In the composition for hair according to one aspect of the present invention, the group introduced into the side chain of the side chain-type cationic polymer includes a C ₁ -C ₂₂ hydrocarbon group.

The side chain-type cationic polymer forms a complex of a relatively flexible structure with an anionic surfactant in the composition for hair as compared with the linear cationic polymer. This is thought to be due to the steric hindrance effect by the hydrophobic group. Accordingly, when the hair composition contains a cationic polymer having a side chain type, the hair is less likely to accumulate on the hair because of its low adsorption ability to the hair, thereby reducing the hair oil and the itchiness of the hair and causing fever, scalp rash, erythema .

The composition for hair according to one aspect of the present invention comprises a nonionic surfactant. In the present specification, a surfactant means a substance that adsorbs at the interface in a solution to decrease its surface tension.
