Provided are leave-on hair care compositions which can impart enhanced hair conditioning and damage protection, while being formulated in a low viscosit y product. In particular, the atomizible leave-on hair care composition comprise: (i) from about 0.1 % to about 10 %, by weight, of a cationic cross - linked polymeric conditioning agent comprising the monomer units (A)m(B)n(C) p and a cross-linking agent wherein: (A) is a dialkylaminoalkyl acrylate monom er or a quaternay ammonium or acid addition salt thereof; (B) is a dialkylaminoalkyl methacrylate monomer or a quaternary ammonium or acid addition salt thereof; (C) is a nonionic monomer polymerizable with (A) or (B); m, n and p are independently zero or greater, but at least one of m or n is one or greater; (ii) from about 0.1 % to about 10 %, by weight, of a salt ; and (iii) from about 0.0001 % to about 0.05 % of at least one polyalkylene glycol corresponding to the structure (I), wherein R is H or CH3 and r is an integer from about 2000 to about 25,000; (d) from about 60 % to about 99.799 9 %, by weight, of a polar solvent; wherein the weight ratio of said cationic cross-linked polymeric conditioning agent to said salt is from about 1:25 to about 25:1; and wherein the viscosity of the composition is from about 10 cP to about 500 cP as measured using a Brookfield Viscometer, Spindel #41, at 2 5 ~C, at 10 RPM for three minutes.
