ABSTRACT:
A method of imparting improved conditioning properties to hair comprising treating the hair with a clear conditioning composition comprising a quaternary ammonium compound, such as dicetyldimonium chloride; an amidoamine compound 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; a volatile conditioning agent, such as a volatile hydrocarbon compound or a volatile silicone compound, like cyclomethicone; a solubilizing nonionic surfactant, like lauryl pyrrolidone; and a polyhydric compound, such as a glycol, a triol or a polyol, like hexylene glycol. The clear conditioning composition unexpectedly provides improved hair-conditioning properties, such as wet and dry feel, wet and dry combing, less coating, increased body and overall hair condition to treated hair.
