This study analyzed the swelling behavior of human hair during permanent waving treatment, finding that both the microstructure and macrostructure of intermediate filaments swell simultaneously at the initial stage, and while partially destructed by reduction, they are considerably restored through oxidation.

This study reports that the new neighborhood face index (NFI) demonstrates a remarkably high correlation with the physiochemical properties of benzenoid hydrocarbons, highlighting its potential as a predictive tool.

The method effectively analyzes human hair proteins, especially nonfilamentous ones.

This study found that maternal early-pregnancy serum ferritin concentrations were associated with lower DNA methylation levels at specific CpG sites in cord blood, with some associations persisting into childhood.

This study found that the observed isotropic ss-ECD spectrum of finasteride is influenced by the anisotropy of locally oriented crystals, offering new possibilities for analyzing solid-state chiral materials.

This study found significant correlations for copper and zinc levels between hair and plasma in Pomeranian and Labrador dogs, but no significant correlation for iron.

This case study describes a 14-year-old girl with pili annulati who had fragile hair, which may be due to cavities within the hair shafts as seen in electron microscopic examinations.

This article reviews the role of polarity proteins in epidermal morphogenesis and homeostasis and discusses how their alteration may contribute to skin disease, but reports no new experimental findings.

This study reported that polarized dermoscopy was better for visualizing vascular patterns, scaling, and reticular pigmentation, while nonpolarized mode better documented features like black dots and tapered hair in various hair and scalp conditions.

PMS nanoparticles improve damaged hair by protecting and restoring its surface and color.

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 model study describes how interactions between hair keratin and various materials alter hair's physical and mechanical properties by affecting noncovalent bonds.

This study found that the cuticle layer of hair contributes approximately 60% to bending stress, highlighting its significant role in the mechanical properties of hair stiffness.

This study found that keratin intermediate filaments in the hair of patients with giant axonal neuropathy were structurally altered, resulting in hair that was stiffer, stronger, and more extensible.

This study proposes a new mathematical model, the Harmonic Mean equation, for precisely quantifying nuclear pleomorphism in breast cancer grading, showing high performance with accuracy, recall, specificity, precision, and F1-score metrics.

This article introduces a new theory on male pattern baldness, attributing it to scalp pressure affecting hair follicles, and suggests it could revolutionize understanding and treatment; no clinical results are presented.

This study found that exposure to extremely low-frequency electromagnetic fields at specific intensities significantly enhanced human hair follicle cell activation and proliferation, suggesting a potential new treatment approach for alopecia.

This study determined the stability constants of finasteride complexes with cobalt, zinc, cadmium, and copper, which may inform analyses of blood samples.

This study found that shampoo and conditioner do not alter hair's molecular structure, while perming treatments significantly affect keratin and intermediate filament structures due to bond alterations.

This study showed that chemical and mechanical treatments significantly alter the nanoscale surface properties of hair, affecting its roughness, mechanical stiffness, adhesion, and surface potential.

This study investigated the electron transfer processes in an iron-mediated DAMO–anammox system, finding that Fe3+ accelerated c-type cytochrome-mediated electron transfer and suggested that riboflavin acts as an electron shuttle and DIET may occur among these microorganisms.

This study found that mouse type II spiral ganglion neurites in vitro avoided laminin and high concentrations of fibronectin, indicating both can guide neurite paths differently than type I neurites.

The researchers reported that certain physical characteristics of hair shafts, such as length and color, may influence mtDNA read counts and degradation state when analyzed by massively parallel sequencing.

This study found that lead treatment enhances the imaging of organized hair lipid structures, revealing their orientation and possible composition as lead and calcium soaps, with potential applications in various fields.

In this study, combining photobiomodulation therapy and pulsed electromagnetic field therapy over 24 weeks significantly increased hair density in androgenetic alopecia patients compared to a sham device control, with minimal side effects reported.

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 found that sodium and potassium levels in scalp hair might be sex-specific indicators, while females had slightly higher copper and iron levels, particularly during the reproductive period.

This study suggests that minoxidil sulfate and pinacidil do not activate K channel currents in hair follicles, indicating their hair growth effects may occur through other mechanisms like increased blood flow.

This study found that particle affinity was stronger on healthy hair compared to damaged hair, with the deposition influenced predominantly by hydrogen bonding and electrostatic attraction, while larger particles had poorer deposition.
