Light scattering from human hair fibers [PDF]
ACM Transactions on Graphics, 2003 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.

Dataset from the uniaxial tensile testing of human curly hair fibers under different conditions [PDF]
Data in BriefIndividual human hair fibers exhibiting a curly morphology were procured from a female donor within her early thirties (30s). The selected hair fibers donor had refrained from undergoing any form of chemical treatment, including dyeing, relaxing, and ...

Understanding Curly Hair Mechanics: Fiber Strength [PDF]
Journal of Investigative Dermatology, 2020 The relationship between the geometric and mechanical profiles of hair fibers has been studied, with special focus on curly samples. Incidental observations pointed to a significantly different viscoelastic character with varying curliness. Further investigations confirmed initial observations, showing an initial distinct toe region behavior for curly ...

Experimental Investigation of Shrinkage of Nano Hair Reinforced Concrete [PDF]
Iranica Journal of Energy and Environment, 2013 Basically most of cement based mixtures are likely shrinking. Use of fibers is not a new idea in this case. Previously, there were some evidences that horse hair, straw and cotton fibers were used in mud and mortars in ancient times.

Flexabrasion Applied to the Evaluation of the Photodegradation of Hair Fibers
Cosmetics, 2021 Solar radiation is a significant source of damage to hair fibers. However, the instrumental measurement of the consequences of its interaction with hair fibers’ constituents remains a challenge. In this work, the flexabrasion methodology was investigated
