This study reported that a new coating made with delaminated Ti₃C₂ MXene nano-sheets and a tea-derived compound effectively protects hair keratin from damage by providing UV screening, thermal dissipation, and antioxidation, while also enhancing mechanical strength and restoring wettability.

Different oils affect hair flexibility and strength, with their impact varying on whether hair is virgin or bleached.

This study's simulations suggest that biomechanical factors, like follicle geometry and tissue stiffness, are likely significant in hair fiber protrusion, providing a framework for future experimental validation.

In this study conducted in female mice, maternal Faecalibacterium pathobionts combined with a low-fiber diet increased systemic inflammation and skin problems in offspring, suggesting a link to atopic dermatitis and the influence of dietary trends on chronic conditions.

This review highlights the critical role of microRNAs in regulating hair follicle biology, significantly impacting wool and cashmere development by modulating gene expression and signaling pathways in sheep and goats.

This study found that for straight hair, friction mainly influences fragment formation during combing, suggesting no direct connection to tensile fatigue failure, while with textured hair, combing performance may be more complex.

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.

This study found that the tensile strength of curly hair is influenced by two main components, with springiness (toe region) contributing significantly, unlike in noncurly hair where it is negligible.

This study found that in naturally curved human scalp hairs, distinct arrangements of cell types on either side of the hair fiber contribute to its curvature.

This study found that differences in cashmere fiber diameter in Tibetan cashmere goats are associated with variations in metabolic, hypoxic, and stress response-related proteins, offering insights for breeding strategies.

This study found no significant difference in the tensile properties of hair from different scalp positions, suggesting that microscopic structural heterogeneities may play a role.

This study developed a multifunctional dressing with the MeGel-SFSR composition, which showed faster healing and better tissue regeneration in diabetic wounds compared to controls, by utilizing a herbal compound and enhanced mechanical support, promoting hair follicle regeneration, collagen deposition, reduced inflammation, and vascularization in vivo.

This study found that specific genetic variations in the IRF2BP2 gene influence fleece structure in sheep, with one variant completely determining coat type and another significantly modifying fiber characteristics, providing valuable insights for improving fleece quality through selective breeding.

This study assessed the effects of chemical treatments on hair fiber integrity and found that conditioners with vegetable oils like jojoba and coconut enhanced hydrophobicity and reduced combing friction except for jojoba, while participants preferred these oil-containing conditioners over the base formulation.

Merkel cells likely attract sensory nerve fibers.

This review discusses selection signatures and selective sweeps in fiber-producing animals and recommends further genomic investigations to identify genes related to important fiber traits, without providing new results.

In this study, researchers observed that even a single session of hair dyeing can damage hair fibers, with significant worsening of mechanical properties and protein composition after three or more consecutive treatments, emphasizing the need to consider the cumulative impacts of dyeing on hair health.

This study found that rhodamine B penetrated human hair fibers more effectively from an aqueous solution compared to a methanol/ethanol solvent, with penetration depending on hair morphology.
