This study found that using near-infrared optics, specifically in the second NIR window, allows for effective noninvasive evaluation of intra-hair damage caused by cosmetic treatments, demonstrating distinct damage types and changes in hair condition due to chemical or thermal processes.

This study discusses that permanent hair straightening can be achieved at neutral or acidic pH conditions, with varying effects on cystine and lanthionine levels, by inducing supercontraction of the hair fiber.

This study investigated the tensile response and morphological changes of different ethnic hair types using AFM, showing variations between virgin, chemically damaged, and conditioner-treated Caucasian hair under different conditions.

In this study, the relaxed overhand knot method demonstrated its effectiveness in measuring the self-friction coefficient of single hair fibers, revealing that sodium hydroxide treatment significantly increases friction and could aid microsurgical applications.

This study suggests that the amino acid composition of fibrous proteins in normal human hair is similar to that of stratum corneum proteins, particularly in cysteine and glycine content.

This study found that calcium, magnesium, and vitamin D supplementation altered hair calcium and magnesium content in perimenopausal women, suggesting an early indicator of metabolic changes linked to skeletal mineralization.

This study found that children with pituitary dwarfism had higher zinc and copper hair concentrations and lower manganese concentrations compared to healthy children.

This study found that polyamines enhance genome integrity by facilitating homologous recombination-mediated DNA repair, suggesting a novel role for polyamines beyond promoting cell growth and proliferation.

This study found that DNMT1 promotes adipogenesis in hair follicle stem cells by regulating the miR-214-3p/MAPK1/p-ERK1/2 pathway, suggesting potential applications in stem cell therapy.

In this study, incorporating a novel amino acid compound into a hair-straightening formulation improved humidity-resistant straightening and enhanced the surface and mechanical properties of hair fibers, including increased bending stiffness, reduced friction, and better shape retention under high temperature and humidity conditions.

This study found that improved protein extraction methods enhanced the resolution of hair proteins on gels, but differences in protein abundance between curly and straight Japanese women’s hair were minimal and unlikely to affect hair structure.

This study reports that patients with Alzheimer's disease have increased levels of polyamines in their hair.

The document concludes that using gadolinium-based contrast agents during MRI can be linked to Nephrogenic Systemic Fibrosis in patients with severe kidney disease.

This study found that hair curvature in merino wool is influenced by differences in cell type length rather than the proportions of orthocortical and paracortical cells.

This study discusses using SEM/EDX for elemental analysis of hair samples in forensic science but notes challenges in detecting certain trace elements from raw hair.

This study found that copper levels varied significantly by gender, while young infants had higher levels of copper, zinc, calcium, magnesium, and iron compared to older age groups.

This study found that mycophenolate may stabilize β-catenin and counteract interferon-γ-induced catagen changes in human dermal papilla cells, which could promote hair growth.

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

Mycophenolic acid may help hair grow by activating pathways important for hair growth.

In this study, reduced serum levels of iron, copper, and calcium were associated with premature graying of hair, suggesting that supplementation might help, but more research is needed to fully understand the relationship.

Scientists made glow-in-the-dark dots from human hair that can detect iron, prevent counterfeiting, and reveal fingerprints.

In this study, researchers developed a long-lasting antibacterial coating for medical implants by anchoring silver nanoparticles onto polyamide surfaces, demonstrating potential to improve implant safety and effectiveness by reducing infection and inflammation.

This study found that multi-hair follicles naturally orient perpendicular to the radial line from the crown whirl, suggesting that perpendicular transplantation of grafts could replicate this natural appearance.

This study conducted in situ tensile loading experiments with atomic force microscopy to observe how conditioning treatments affect the tensile response of virgin, chemically damaged, and mechanically damaged Caucasian hair.

The authors concluded that controlling voltage, pulse width, and calcium concentration in pulse electric field-activated platelet-rich plasma enhances the release of growth factors and serotonin without causing clot formation, suggesting potential clinical advantages over bovine thrombin-activated PRP.

This study found that specific genetic markers near the androgen receptor gene are significantly more common in men with male pattern baldness, suggesting a genetic component in its development.

This review presents evidence that correlations exist between hair mineral imbalances and various diseases, though inconsistencies in results highlight the need for standardized preparation methods.

This study found that polyamines participate in DNA double-strand break repair, primarily by enhancing the homologous recombination pathway through RAD51-mediated DNA strand exchange.

This study investigates calcium and phosphorus accumulations in the hair of mummies from the Taklamakan desert and debates their exogenous or endogenous origin.
