Complexity theory is used here to explain the formation and properties of polyelectrolyte complexes, whereby organized structures built through self-association exhibit synergistic properties. These materials can create new compounds and offer new benefits, as shown by the present work in which a complex based on PVM/MA copolymer and polyquaternium-28 is used to treat damaged hair.

Formulations containing quaternary-modified olefin-graft polymers are shown here to improve the permanency of artificial hair colorant in human hair exposed to repeated washing. In addition, when these polymers were applied to hair by a sulfate-based shampoo, the foam height and viscosity of the shampoo remained unaffected.

Generally, the primary goal of hair-growth products is not to cure a condition but to prevent hair loss and promote hair growth. Several hair growth ingredients currently available provide this effect by accelerating blood flow. This article excerpt* describes mechanisms of hair loss and materials to treat it.

Polyquaternium-74 is a synthetic high performance conditioning polymer whose flocculation and deposition characteristics enable it to match or outperform traditional conditioning polymers in detangling, overall hair conditioning, shine enhancement and buildup reduction when combined, as shown here, with a submicron dimethicone emulsion. Benefits are noted for 2-in-1 shampoo formulations.

Crotonic acid/vinyl C8–12 isoalkyl esters/VA/bis-vinyldimethicone crosspolymer is a new hybrid polymer for use in hair sprays. This highly branched block copolymer is shown to give hair a firm hold yet soft, natural feel. It is recommended for use in quick-drying, low-tack hair sprays with high water content.
