TLDR A new method helps understand hair shine and various products improve hair care.
The study by A. John McKinnon used a reciprocal lattice approach to model light scattering by periodically deformed hair fibers, successfully reproducing several features of experimentally observed scattering and providing a three-dimensional understanding of hair luster. Additionally, the document reviewed various hair care products: antioxidants in sun care formulations showed some protective effects but sometimes reduced tensile strength; silicones in hair dyes reduced color fading; a new emollient enhanced hair shine; arginine protected against oxidative damage in hair coloring agents; the Bradford assay was proposed for quantifying protein loss; polymethylene waxes improved conditioning and shine in hair relaxers; new cationic cellulosic polymers showed superior conditioning in shampoos; and enhanced delivery of Octopirox® in a shampoo vehicle was demonstrated.
