research An Innovative Experimental Petrographic Study of Concrete Produced by Animal Bones and Human Hair Fibers
Concrete made from animal bones and human hair is stronger and more environmentally friendly than traditional concrete.
research A discrete transition zone between cuticle and cortex layers of a human hair fibre: changes observed in the presence of breast cancer
Breast cancer alters specific molecular structures in hair, which revert after cancer removal.
research In vitro methodology, hormonal and nutritional effects and fibre production in isolated ovine and caprine anagen hair follicles
Angora goat hair grows faster and produces more protein than cashmere goat hair, and certain hormones and nutrients positively affect hair growth and protein synthesis.
research Distribution and Localization of Hydrophobic and Ionic Chemical Groups at the Surface of Bleached Human Hair Fibers
Bleaching hair removes its protective top layer and exposes more hydrophilic groups, changing its chemical surface and affecting how it interacts with products.
research Deficiency in Nucleotide Excision Repair Family Gene Activity, Especially ERCC3, Is Associated with Non-Pigmented Hair Fiber Growth
Low ERCC3 gene activity is linked to non-pigmented hair growth.
research Study of the Physicochemical Properties of Different Hair and Body Shampoo Samples Available in the Local Market of Al Khums, Libya
Hair and body shampoos differ in properties to meet specific needs for hair and skin.
research Understanding Curly Hair Mechanics: Fiber Strength
Curly hair is mechanically different from straight hair and may need new testing methods.
research Organization of microfibrils in keratin fibers studied by X-ray scattering
The study improved understanding of keratin fiber structure by showing consistent microfibril diameter but varying distances and electron density profiles.
research Experimental Confirmation of a Distinctive Diffraction Pattern in Hair From Women With Breast Cancer
A specific hair diffraction pattern may indicate breast cancer if tested with the correct method.
research Analysis of heterogeneous reaction between reducing agents and keratin fibers using Raman spectroscopy and microspectrophotometry
The study found that thioglycolic acid breaks down hair bonds more consistently than l-cysteine, which is less damaging to hair.
research Effects of melatonin administration to cashmere goats on cashmere production and hair follicle characteristics in two consecutive cashmere growth cycles
Melatonin improved cashmere production in goats during the first cycle but had no lasting effects on the next cycle.
research Giant Cells in Male Pattern Alopecia: a Histologic Marker and Pathogenetic Clue
Giant cells found in some male pattern baldness cases may help diagnose it and suggest hair is mistakenly seen as foreign by the body.
research The effects of melatonin treatment on wool production and hair follicle cycle in angora rabbits
Melatonin treatment increases wool production and improves fiber quality in angora rabbits.
research Scanning Electron Microscopy and X-ray Microanalysis of Reconstructive Hair Fibers.
All five hair fiber products improved appearance but didn't stick to completely bald areas.
research Human Hair: An Important Biological Matrix of Interest
Human hair is a significant sample for various tests in clinical, nutritional, archaeological, and forensic studies.
research Raman spectroscopic analysis of L‐phenylalanine and hydrolyzed eggwhite protein penetration into keratin fibers
L-phenylalanine and hydrolyzed eggwhite protein deeply penetrate human hair.
research Influence of urea on the coloring ability of a low‐temperature coloring method of keratin fibers using polyethyleneimine
Urea helps hair dye penetrate better and last longer.
research Hair analysis in health assessment
Hair mineral analysis might help diagnose diseases early, but standard methods are needed.
research Cortical cell types and intermediate filament arrangements correlate with fiber curvature in Japanese human hair
Hair curvature in Japanese people is linked to specific cell types and filament arrangements in the hair cortex.
research Identification of the Ovine Keratin-Associated Protein 22-1 (KAP22-1) Gene and Its Effect on Wool Traits
The gene KAP22-1 affects wool yield and fiber shape in sheep.
research Dietary supplementation with Essential-oils-cobalt for improving growth performance, meat quality and skin cell capacity of goats
