Disclosed are mild hair conditioning compositions comprising by weight: (a) from about 0.5 % to about 5.0 % of an amidoamine; (b) from about 0.05 % to about 2.0 % of an acid; (c) from about 0.1% to about 15 % of a fatty compound selected from the group consisting of fatty alcohols, fatty acids, fatty alcohol derivatives, fatty acid derivatives, and mixtures thereof; and (d) water; wherein the pH of the composition is from about 4.5 to about 6, or the mole ratio of the amidoamine to the acid is from about 1:0.3 to about 1:1.0. In a preferred embodiment, the fatty compound is selected from the group consisting of pure cetyl alcohol, pure stearyl alcohol, and pure behenyl alcohol. In another preferred embodiment, the hair conditioning composition is made by a method comprising the steps of mixing the amidoamine, the acid, and water at an elevated temperature, followed by addition of the fatty compound.
