1. A shampoo formulation, comprising:
a dermatologically acceptable vehicle;
a dermatologically acceptable silicone;
a sodium lauryl ether surfactant, wherein the sodium lauryl ether surfactant is selected from the group consisting of a sodium lauryl ether sulfate having an average of two —(OCH2CH2)— groups per molecule, a sodium lauryl ether sulfate having an average of three —(OCH2CH2)— groups per molecule and mixtures thereof;
a deposition aid polymer, wherein the deposition aid polymer is a cationic dextran polymer, comprising a dextran polymer functionalized with quaternary ammonium groups; wherein the dextran polymer has a weight average molecular weight of 50,000 to 3,000,000 Daltons; wherein the quaternary ammonium groups are selected from the group consisting of quaternary ammonium moieties of formula (A) bound to a pendent oxygen on the dextran polymer
