Advances in Polymers for Hair Conditioning Shampoos
By: Robert Y. Lochhead and Lisa R. Huisinga, Schoo…
The dilution-deposition mechanism is the core of the modern conditioning shampoo. It is described here, along with polymer inventions that enhance benefits and improve the clarity of conditioning shampoos, and enable conditioning from shampoos that do not contain a cationic polymer.

Inside the Hair: An Advanced Hair Biology Model
By: Randy Schueller and Perry Romanowski, Alberto-…
In this survey from the literature, various writers describe a model of the inside of a hair strand, showing a multilamellar structure of the cuticle cells, a multifibril structure of the cortex, and a variety of lipids that are thought to be major contributors to the hair’s physical properties. What exactly is hair? Simply put, the answer is that hair is protein. But this simple answer does not even begin to explain the complexity and sophistication of the hair fiber.

Advances in Polymers for Hair Coloring
By: R.Y. Lochhead, The University of Southern Miss…
This article surveys patents and technical literature, principally from the past 10 years, to report advances in polymers used for dyeing hair, color retention,and hair lightening. Associative thickeners (anionic, cationic, amphoteric, nonionic, HASE, HEUR), nonassociative thickeners, and silicones are discussed.

Cyclic Testing: Demonstrating Conditioner Benefits on Damaged Hair
By: Sidney B. Hornby, Mar-Tech Contract Services I…
Cyclic fatigue testing simulated stresses experienced by hair fibers from repeated grooming and styling. Researchers used the Weibull parameter of characteristic life to assess damage. Survival probability graphs showed conditioner use helped damaged hair.
