Abstract: A formulation for the care of damaged hair is provided, comprising: a vehicle; a silicone; and a deposition aid, wherein the deposition aid is a cationic dextran polymer, comprising a dextran base polymer functionalized with quaternary ammonium groups; wherein the dextran base polymer has a weight average molecular weight of 50,000 to 3,000,000 Daltons; wherein the quaternary ammonium groups include (i) a quaternary ammonium group of formula (II) bound to a pendent oxygen on the dextran base polymer




(ii) a quaternary ammonium group of formula (III) bound to a pendent oxygen on the dextran base polymer




wherein




is pendent oxygen on the dextran base polymer; wherein X is a divalent linking group; wherein each R2 is independently selected from a C1-4 alkyl group; wherein each R3 is independently selected from a C1-4 alkyl group; and wherein each R4 is independently selected from a C5-20 alkyl group.
