Disclosed is a quick dispersing hair conditioning composition comprising (a) an isostearamidopropyl ethyldimethylammonium salt or a dicocodimethylammonium salt; (b) one or more fatty alcohols; (c) dimethicone; and (d) water. The hair conditioning composition of the invention has one or more advantageous properties. For example, an embodiment of the invention has a dispersion rate such that when 1.5 mL of the composition is dispersed into 400 mL of water at about 35° C. to about 40° C., the dispersion has a transmittance at 420 nm that is less than about 70% of the water at the same temperature in less than about 120 seconds.
