ABSTRACT:
A method of imparting improved conditioning properties to hair comprising treating the hair with a composition comprising a water-soluble quaternary ammonium compound, such as cetrimonium chloride; an oil-soluble, water-dispersible quaternary ammonium compound, such as distearyldimonium chloride; an acid-neutralized amidoamine compound, wherein an amidoamine having the general formula: ##STR1## wherein R.sub.1 is a fatty acid chain containing from about 11 to about 21 carbon atoms, R.sub.2 is an alkylene group containing from two to about four carbon atoms, R.sub.3 is hydrogen, methyl, ethyl or a hydroxyalkylene group containing from one to about three carbon atoms, R.sub.4 is methyl, ethyl or a hydroxyalkylene group containing from one to about three carbon atoms, and Y is a heterocyclic nitrogen-containing moiety, like morpholine or pyridine, is neutralized with a suitable acid, such as the amidoamine compound stearamidoethylethanolamine neutralized with phosphoric acid; and a low molecular weight polydimethylsiloxane compound, such as cyclomethicone. The method and composition unexpectedly provide improved hair-conditioning properties such as wet feel, wet and dry combing, manageability, sheen, luster, body and overall hair condition.
