Abstract
The present invention relates to rinse-off hair care compositions that leave a low residue on the hair. These compositions have good hair style retention properties and have a natural, non-sticky feel upon the hair. These compositions comprise a hydrophobic copolymer component having a drying coefficient of less than about 3% and a carrier suitable for application to the hair. The copolymer component further comprises a hydrophobic copolymer and a volatile hydrophobic solvent. The copolymer has a cohesive breaking strength of greater than about 20 kg.sub.f /cm.sup.2, an adhesive strength of less than about 30 kg.sub.f /cm.sup.2, a cohesive breaking strain of less than about 100%, wherein the ratio of said cohesive breaking strength to said adhesive strength is greater than or equal to about 1.
