This paper reviews various techniques for measuring the physical and mechanical properties of human hair fibers, emphasizing their importance in developing effective cosmetic products.

This study demonstrated that the differential wetting characterization (DWC) method can effectively differentiate changes in the wetting properties of hair fibers after chemical or physical treatment.

Minoxidil treatment in mice preserved the integrity of elastic lamellae and improved arterial biomechanical properties, especially in females, suggesting it could be an anti-arterial aging agent potentially suitable for female-targeted therapies.

This study identified polymorphisms in HGT-KRTAP7-1 and KRTAP8-1 genes in Argentine llamas that may impact fiber characteristics by altering amino acid residues critical for keratin-associated protein properties.

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 dyed chitin nanofibers maintain color and mechanical properties when reinforcing resins, allowing color addition and strength improvement while retaining transparency.

In this study, combined treatment with transglutaminase and keratin significantly repaired damaged hair by improving its structural properties, reducing swelling, and enhancing crosslink activities, as evidenced by microscopy and spectroscopy analyses.

In this study, researchers found that the morphology, composition, and elemental enrichment of domestic cat hairs vary significantly along their length, contributing to a functional gradient that affects mechanical properties and challenging assumptions of uniformity in hair structure.

This study found that repeated exposure to ozonated water caused oxidative changes in hair proteins, lipids, and pigments, leading to altered hair properties, with minimal effects on shine and color.

This study reported that nanofibrous scaffolds made from a PVA and flaxseed extract combination showed enhanced antimicrobial activity and significantly better wound healing in vitro compared to pure PVA fibers.

This study found that individual differences between pigmented and unpigmented hair fibers in Old Order Mennonites suggest grey hair may be perceived as drier and less manageable due to small mechanical and moisture changes.

This study identified a unique concentric double-layered structure in both Japanese and Caucasian SHINAYAKA hair, associated with improved flexibility and elasticity, and developed a succinic acid treatment to enhance these properties.

This review discusses the hierarchical structure and chemical properties of hair fibers and offers insights for chemists and biochemists, but reports no new experimental findings.

This study found that applying botanical extracts improved the mechanical properties of bleached hair, reducing its permeability and increasing its crystalline content.

This study analyzed skin specimens from Australian Merino ewes to estimate hair follicle properties across different strains, providing baseline data essential for future genetic studies on fleece structure, but reported no new conclusions.

This study found that the X-ray patterns of stretched mammalian hair (β-keratin) are similar to those of natural silk (fibrion), suggesting a similar elastic mechanism involving reversible intra-molecular transformations.

This study found that glycylglycine treatment improved hair softness by enhancing hair alignment and altering internal fiber properties among Japanese women with typically coarse hair.

Hair growth can be induced by certain cells found at the base of hair follicles, and these cells may also influence hair development and regeneration.

Hair treatments like bleaching increase friction by exposing tiny pores on the hair surface.

This study found that cultured papilla cells can induce follicle formation and hair growth when combined with different epidermal and dermal cells, highlighting their powerful inductive properties and potential for dermatological applications.

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 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 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 discovered a conserved "fiber-like-motif" of melanosomes aligned in hair across various mammalian species, shedding light on the internal structure that influences hair's thermal and mechanical properties.

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.

This Ph.D. project aims to evaluate the self-assembling potential of hair keratin extracts and study the cellular response to both crude and purified keratins, highlighting their potential applications from biomedical to water remediation.

This study explores torsional measurements of single hair fibers to differentiate the effects of cosmetic treatments on hair structure, highlighting their potential to reveal shear stiffness changes related to cuticle damage.

In this review, the authors highlight a lack of understanding regarding the unique properties of Afro-textured hair, emphasizing the need for scientific collaboration to improve hair care practices and mitigate scalp issues.

This study reviewed literature on using vegetable oils to prevent skin aging, highlighting their antioxidant properties and their role in combating free radicals, which leads to extrinsic aging, while also noting Brazil's important contribution to this field with its rich natural resources.

In this study, a new delipidisation method that removes over 97% of key lipids from wool rapidly and without yellowing was reported to improve wool processing and printing quality.
