1. A hair conditioning composition comprising by weight:
(a) from about 0.3% to about 8% of a cationic surfactant system comprising a mono-long alkyl cationic surfactant and a di-long alkyl cationic surfactant wherein the mono-long alkyl cationic surfactant is selected from the group consisting of behenyl trimethyl ammonium methyl sulfate, behenyl trimethyl ammonium ethyl sulfate, and mixtures thereof, and wherein the di-long alkyl cationic surfactant is selected from the group consisting of dicetyl dimethyl ammonium chloride, distearyl dimethyl ammonium chloride, and mixtures thereof; (b) from about 3% to about 10% of a fatty alcohol selected from the group consisting of cetyl alcohol, stearyl alcohol, behenyl alcohol and mixtures thereof; (c) from about 0.00005% to about 0.5% of a direct dye; and (d) from about 0.01% to about 0.1% of a nonionic thickening polymer wherein the nonionic thickening polymer is selected from the group consisting of hydroxyethylcellulose, hydroxypropylcellulose, cetyl hydroxyethylcellulose and mixtures thereof; (e) an aqueous carrier, wherein the hair conditioning composition has a pH of from about 5.5 to about 8.0 wherein the weight ratio of the di-long alkyl cationic surfactant to the mono-long alkyl cationic surfactant in the cationic surfactant system is within the range of from 1:1 to 1:10, and wherein the hair conditioning composition is free of an anionic polymer and wherein the direct dye is nonionic nitrobenzene derivatives and wherein the nonionic nitrobenzene derivatives is 4-hydroxypropylamino-3-nitrophenol wherein the hair conditioning composition comprises from about 0.1 to about 20% of a silicone compound and wherein the silicone compound is an aminosilicone compound, and wherein the hair conditioning composition is substantially free of anionic surfactants and is a rinse-off conditioning composition.
