Capturing hair assemblies fiber by fiber
ACM SIGGRAPH Asia 2009 papers, 2009Hair models for computer graphics consist of many curves representing individual hair fibers. In current practice these curves are generated by ad hoc random processes, and in close-up views their arrangement appears plainly different from real hair.

Effect of Waste Human Hair Fibers on Shear Behavior of Sand in Dry and Saturated Conditions
Journal of Testing and Evaluation, 2018Soil reinforcement using natural fibers has been successfully employed in different projects. Among the natural fibers, the use of waste human hair fibers as a reinforcing material can be the solution for sustainable development.

Photoageing of Hair Fiber and Photoprotection
Skin Pharmacology and Physiology, 1994Examination by transmission electron microscopy of hair exposed to sunlight has revealed important damage. Findings indicate an alteration of various cell components. Damage occurs in the cuticle and leads to its loss. Separation of macro-fibrils and destruction of melanin pigments result in cortex damage.

Metaplexis japonica seed hair fiber: a member of natural hollow fibers and its characterization
Textile research journal, 2019Metaplexis japonica seed hair fibers (Mj-fiber), harvested from the seed pods of Metaplexis japonica (Apocynaceae: Asclepiadoideae) originating in China, Japan and Korea, have features ensuring its potential application in the textile and other ...

Fiber-Reinforced Mortar Incorporating Pig Hair
Advanced Engineering Forum, 2017Recycled fibers from food-industry could be added as reinforcement to cement-based materials. Cement-based materials perform well under compression, but tensile strength and post-cracking ductility in tension are poor. Fibers produced from steel, glass and synthetic materials, have been successfully used to overcome some of these shortcomings.

Wetting behavior of human hair fibers
Journal of Applied Polymer Science, 1978AbstractThe wetting behavior of human hair in water has been investigated using a technique based on the Wilhelmy balance principle. The experimental technique makes it possible to study the relaxation effects occurring at the solid–liquid–air interface.

Menkes Kinky Hair Disease with ‘Ragged Red’ Fibers
Developmental Medicine & Child Neurology, 1988SummaryA 30‐month‐old infant with Menkes kinky‐hair disease died, with prominent vascular, cerebral and cerebellar degeneration. Increased numbers of mitochondria containing homogeneous dense bodies were seen on electron–microscopic: examination of Purkinje cells.

Is polar bear hair fiber optic?
Applied Optics, 1998New direct measurement of high optical attenuation rates in polar bear hairs--2-8 dB/mm in the visible--and reanalysis of the data of Tributsch et al. [Sol. Energy Mater. 21, 219 (1990)] seem to rule out the UV waveguiding proposed by Grojean et al. [Appl. Opt. 19, 339 (1980)].

Investigating the relationship between the hair fiber proteome and hair quality
International Journal of Cosmetic Science, 2004Many hair characteristics (e.g. color and curl) are genetically determined. Here, we investigated whether hair quality is also genetically controlled and related to differences in hair composition. Female, Caucasian subjects (n = 292) were recruited into this study and segmented by self‐perceived hair quality and by permanent colorant usage.

Fiber-Safe Extraction of Red Mordant Dyes from Hair Fibers
Journal of the American Institute for Conservation, 1995To extract red mordant dyes from wool fiber samples, a new method was devised using a solution of 0.1% ethylene diamine tetraacetic acid in water combined with N,N-dimethyl formamide.
