    • Terpolymers with more than one constituent cationic monomer, further copolymerized with acrylamide, are conditioning additives for hair, skin and nail care products which, with regard to hair, improve wet and dry hair combability, especially detangling and reduced static flyaway, sheen, and fixative properties, especially curl retention, and with regard to skin and nails, improve softening or lubricating (lubricity), moisture retention and attraction (moisturizing), feel, and reduction of irritation. The dual cationic polymers may have a weight average molecular weight of from about 10 thousand to 10 million, and comprise (a) from at least 30 to as much as 75 weight percent of acrylamide (AM), (b) from at least 25 to as much as 80 weight percent of the cationic monomer dimethyldiallylammonium chloride (DMDAAC), and (c) from at least 5 to as much as 35 weight percent of a second cationic monomer of the formula: ##STR1## where Y is --O--A-- or --NH--A--, where A is ethyl or propyl; R.sup.1 is H or CH.sub.3 ; R.sup.2, R.sup.3 and R.sup.4 are independently selected from H and C.sub.1-12 alkyl; and X.sup.- is a suitable anion, especially .sup.- Cl and .sup.-OSO.sub.3 CH.sub.3.
