In this study, researchers found a significant decrease in the modulus of elasticity of hair shafts in premature neonates compared to full-term ones, potentially due to differences in disulphide bonds or microfibril arrangement.

This study found that biotinoyl tripeptide-1-loaded solid lipid nanoparticles significantly improved thermal protection in hair, enhancing cuticle integrity and resistance to heat damage, compared to control samples.

In this study, BTP-loaded solid lipid nanoparticles were developed and shown to protect hair from heat-induced damage by enhancing cuticle integrity and thermal resistance in simulated thermal straightening conditions.

This study found that oxidized hair undergoes time-related structural changes, resulting in improved thermal and mechanical stability over several months after moderate or intense oxidative treatments.

Scientists found gene mutations that affect hair loss, skin stem cells, and skin disorders, and identified drugs that may help treat blood vessel and skin conditions.

This study found that Mf-rich-fiber in human hair underwent significantly greater degradation by proteases than Ma-rich-fiber, especially when treated with Proteinase K.

This study describes the presence of holes in hair fibers, absent in hair follicles, likely forming from daily care actions and removal of extractable substances.

In this study, hair shafts from trichothiodystrophy patients with ERCC2 mutations revealed abnormal cuticle structures and protein imbalances compared to normal hair shafts.

This study suggests that holes found in mature hair fibers may be linked to daily hair care actions and the removal of extractable substances.

This study observed that surfactants in cosmetic treatments can bind to keratinous tissues like hair and nails, affecting their tensile properties and possibly leading to deterioration depending on the specific detergents used.

This study found that medullary cell content in mammal hair evolves from an amorphous form to a biphasic phase, with human and anthropoid hair containing both macrofibrils and microfibrils.

This study identified two types of hard alpha-keratin filament assemblies in developing human hair follicles, which may help investigate the structural framework of mammalian keratin appendages.

This study demonstrated that human hair shafts can be anatomically separated to obtain intact micron and nano keratin filaments using solvents like performic acid and urea.

This study found that the structural and chemical composition of human curly hair may resemble that of sheep wool, implying a shared characteristic among mammals with wavy hair.

This study observed that hair fibers in older women become more curved with age, decreasing hair luster due to their disordered alignment and structural differences between the convex and concave sides.

This study demonstrated that keratin can be effectively extracted from wool using alkaline solutions and that the extracted keratin maintains reactivity similar to that from other low-value sources like cattle hair.

This study utilized polarized light microscopy to examine hair shafts in ten children with rare genetic disorders, such as Netherton syndrome and ectodermal dysplasia, providing valuable diagnostic insights into hair thickness, composition, and structural irregularities associated with these conditions.

In this research, the author hypothesizes that curly hair is influenced by the contraction of the Arrector Pili muscle, suggesting that its relaxation through specific treatments could potentially modulate hair follicle curvature, but further studies are needed to confirm this mechanism.

This study found that harp seal vibrissal innervation studies focusing only on lateral vibrissae may overestimate total innervation by about 20%, highlighting the importance of considering the entire snout.

This study reports two cases where pili anulati, typically a non-fragile hair condition, showed increased fragility due to androgenetic alopecia, causing hair shaft fracturing in the affected area.

This chapter reviews the complexity of hair and wool follicle formation, emphasizing the importance of cytological studies to understand the relationship between cellular components.

This study reports on the biochemical characteristics of S100A3 protein in human hair cuticle, notably finding its N-terminal methionine is acetylated and has a slightly lower isoelectric point compared to the recombinant version.

This study proposes a new method to selectively isolate keratin-associated proteins and keratin from human hair, suggesting that KAPs may support keratin fibers in hair structure.

This article discusses themes in the molecular structure of hair and reports no new research findings.

This study demonstrated that in live rodents, actin filaments adjust their structure to facilitate membrane transfer between cellular compartments with different biophysical properties.

This study found that the mechanical stiffening of the human hair follicle along the first millimeter is linked to changes in the keratin network architecture and composition during keratinization.

This study found that excessive heat caused the most significant structural changes in hair from Caucasian and Afro samples, especially when combined with other treatments like bleaching and straightening.

This research examined the ultrastructure of deer hair fibers and found significant variations in diameter, cuticle thickness, and intermediate filament arrangements among different fiber types.

This study demonstrated that molecular dynamics simulations of keratin could effectively model the mechanical properties of hair, aligning well with experimental data, especially when conducted in vacuum conditions.

This review covers various aspects of hair biology, pigmentation, and development, focusing on genetic and biochemical modulation of hair follicle components but reports no new findings.
