The document describes a method for preparing hair for microscopy by embedding it in plastic, cutting it, and storing it cold before imaging.

This study found that hair fibers broke down and lost keratin in extremely basic conditions, revealing the inner medulla and changing the color of the fibers.

This study observed significant differences in hair and cashmere properties among three goat breeds in Southwest China, noting better quality cashmere in Inner Mongolia cashmere goats and their crossbreed compared to Dazu black goats.

This study presents a DNA-analytical method that can reliably identify and differentiate cashmere, fine wool, yak, and camel hair fibers in both untreated and processed samples.

In this study, bleaching and perming were found to significantly reduce opiate concentrations in both spiked and naturally opiate-positive human hair samples.

This study found that examining hair morphology provides deeper insights than classification, suggesting a potential population stratification artefact between hair curvature and cross-sectional shapes in the examined admixed African-European sample.

This study introduced a novel microscopy system using an Er3 + −doped femtosecond fiber laser, achieving detailed imaging of biological structures in plant and skin samples with improved spatial resolution for various applications, including in vivo imaging.

This study developed a quantitative method using SDS-PAGE and MALDI-TOF mass spectroscopy to accurately determine animal species from hair fibers, validated against standard samples and optical microscopy.

In this study, researchers found that a high-cost hair restoration product containing coconut oil and glycerol effectively restored the structural integrity of chemically processed hair, particularly in samples that were significantly damaged by bleaching and color treatments.

This study found that segmental single hair analysis produced ocfentanil concentration profiles similar to those from hair lock analysis, supporting its use in cases with limited samples.

This study observed that prolonged water or soil exposure can lead to significant reductions in drug levels in bleached and natural hair samples.

This study confirms that the proposed universal model for hard α-keratin structure applies to all known forms across various mammalian species.

This study found that a bio-based repair solution containing hydrolysed wool keratin, serine, and transglutaminase improved the physical and chemical properties of damaged hair, increasing its strength, flexibility, and thermal stability while offering long-lasting protection against chemical damage.

In this study, significant changes in hair fiber dimensions were observed between pre- and post-operative states in males undergoing abdominal surgery, with values normalizing by the fourth post-operative week.

This research investigated how moisture absorption impacts human hair structure, finding that moisture sorption kinetics reveal insights into chain entanglement and structural changes due to cosmetic treatments, while also quantifying the influence of sample weight and fiber density on the sorption process.

This study found that specific proteins associated with fiber structure, hair growth, and fatty acid synthesis, including the DSC2 gene, may influence wool and hair characteristics in sheep and goats.

This study found that seasonal changes significantly affected hair follicle activity and fibre growth in Merghoz goats, with variations seen in feed intake and growth patterns across different seasons.

This study found that Bakhtiari sheep hair fibers and follicles became larger and more organized with age across all skin regions, with no significant differences by sex.

In this study, UVB irradiation increased mast cell degranulation only when skin was innervated, suggesting that the interaction between mast cells and nerve fibres may exacerbate solar elastosis by promoting dysfunctional dermal elastic fiber accumulation, but further research is needed for confirmation.

This study found that Cream 1 effectively prevented UV radiation-induced nerve ending damage in human skin samples, unlike placebo and SPF15 creams.

This study introduces a new test using a pendulum device to assess the bending stiffness of hair fibers, which can evaluate the effects of different hair treatments.

In this study of four Chinese goat breeds, black goats exhibited significantly higher melanin content, while Inner Mongolian cashmere goats had longer fiber lengths. These findings highlight genetic variations in coat color and fiber length, informing future breeding programs.

This study found that reinforcing clayey soil with human hair fibers increased its strength significantly, both before and after freeze-thaw cycles, suggesting its potential use in cold climate zones.

This study suggests that ethylene and lignoceric acid (C24:0) may promote cotton fiber and Arabidopsis root hair growth by activating the pectin biosynthesis network.

This in vitro study found that opiate diffusion was more pronounced in damaged hair fibers than in undamaged ones, with high opiate concentrations detected in fiber centerpieces.

The conclusion is that a new method to measure hair shine was confirmed to match people's visual assessments.

This study investigated the penetration of a low-molecular-weight cationic conditioning compound into the hair cortex and suggests it may improve hair's fatigue resistance.

This study introduced a new high-throughput method for analyzing scalp hair morphology and found that quantifying hair form provides more accurate information than traditional classification based on racial categories, challenging the belief that cross-sectional morphology predicts hair curvature.

In this study, the researchers conducted tensile tests on individual curly human hair fibers sourced from a female donor and found distinct mechanical properties under various conditions, including different strain rates and temperatures, both dry and in saline immersion.

This study found that camel hair from Afif has suitable physical and chemical properties for textile production and its characteristics can be enhanced with chemical additives like acetic acid.
