This study found that Magra sheep with high-luster wool exhibited significantly higher expression of keratin genes, suggesting that increased keratin protein levels may be crucial for wool luster.

This study introduced a new method for extracting red mordant dyes from wool fibers that preserved the fibers for further analysis and allowed for spectrophotometric examination of the dyes' absorption curves.

This study describes a new method for extracting red mordant dyes from wool fibers using ethylene diamine tetraacetic acid and N,N-dimethyl formamide, preserving the fibers for further examination.

In this study, researchers found that L-cysteine interacted electrostatically with anionic ions on the surface of keratin fibers in human hair, reducing the rate of disulfide bond disconnection at pH 9.0.

This study found that chemically modifying hair with 2-iminothiorane hydrochloride improved the permanence of hair setting without damaging the hair by increasing disulfide bonds.

This study demonstrated that urea significantly accelerates the diffusion of poly(ethylene imine) into bleached human hair by increasing the diffusion coefficient twofold.

This study found that temperature significantly affects the mechanical properties of rabbit hair fibers, with increased tensile strain and decreased breaking strength in humid conditions.

This study found that polyquaternium-68 at pH 9 achieved the greatest hair deposition, while polyquaternium-44 demonstrated the best wash resistance at pH 6.

In this study, a new shading model for hair was developed that better matches real-life light scattering, thanks to detailed new measurements of hair fiber scattering not predicted by existing models.

This study introduced a new hair shading model that more accurately simulates light scattering on hair fibers, capturing effects not predicted by previous models.

This study found that cultured dental papilla cells from various mammals can induce hair follicle regeneration and influence tissue formation, with outcomes dependent on donor age, tooth type, and host environment.

This study demonstrates that spatially resolved IR and Raman imaging can effectively reveal the molecular structure and composition of untreated human hair, providing insights into its chemistry and structural integrity.

In this study, experimentally induced weight loss in merino sheep led to a decrease in wool fiber diameter and increased expression of certain high sulfur and glycine-tyrosine proteins, potentially impacting wool quality and industry preferences.

In these studies, researchers found that Peruvian camelids reach mature skin follicle development early, with specific cuticular characteristics useful for distinguishing fleece types, while Bolivian llamas have a mature follicle apparatus present at birth.

This study found that polymorphisms in the KAP8.2 gene in Chinese Inner Mongolia cashmere goats are associated with variations in cashmere fibre diameter, suggesting its potential as a molecular marker for this trait.

This study found that alkali bromide solutions are absorbed into hair depending on salt activity, and the presence of the salt increases water absorption compared to normal conditions.

Polyquaternium 7® builds up on hair, improving its look and feel, and AFM is good for measuring these changes.
