1. A hair styling composition comprising at least two latex polyurethane polymers and at least one component chosen from thickening agents, wherein at least one latex polyurethane polymer is a film-forming polymer,
wherein the at least two latex polyurethane polymers are chosen from: (a) polymer A, having a Young's modulus ranging from about 0.1 MPa to about 10 MPa, and a strain, under stress at 0.5 MPa, of at least about 1%; (b) polymer B, having a Young's modulus ranging from about 10 MPa to about 6 GPa, and a strain, under stress at 0.5 MPa, of less than about 5%; and (c) polymer C, chosen from non-film-forming latex polyurethane polymers; wherein the at least two latex polyurethane polymers are present in a combined amount ranging from about 0.1% to about 30% by weight, relative to the weight of the composition; and wherein the at least two latex polyurethane polymers are present in the composition in a weight ratio ranging from about 10:1 to about 1:10. |
