Light scattering from human hair fibers [PDF]
Light scattering from hair is normally simulated in computer graphics using Kajiya and Kay's classic phenomenological model. We have made new measurements of scattering from individual hair fibers that exhibit visually significant effects not predicted by Kajiya and Kay's model.

Effect of Freezing-Thawing on Clayey Soils Reinforced with Human Hair Fibers
The reinforcing of fine-grained soils using natural or synthetic fibers has been successfully applied today. The use of waste human hair fibers among natural fibers is seen as a sustainable solution as a reinforcing material.

Protein Carbonylation as a Reliable Read-Out of Urban Pollution Damage/Protection of Hair Fibers
(1) Background: Environmental factors, such as airborne pollutants and solar UV, induce oxidative damage to proteins and lipids on hair fibers, leading to decreased hair strength and shine, increased fiber porosity, brittleness, dryness, and stiffness ...

Effect of equilibrium pH on the structure and properties of bleach-damaged human hair fibers. [PDF]
Hair proteins are significantly affected by environmental pH. This impact tends to increase with prior hair damage. To understand how pH affects bleached hair properties, we utilized a number of techniques allowing for the determination of hair thermal ...

Human pollution exposure correlates with accelerated ultrastructural degradation of hair fibers. [PDF]
Significance Air pollution via phototoxic polycyclic aromatic hydrocarbons (PAHs) is a major risk factor for human health. While in vitro observations and in vivo correlations suggest a detrimental effect of PAHs at physiological concentrations, in vivo ...
