This study suggests that elevated copper levels in domestic tapwater, exacerbated by its aggressive properties, likely contribute to green hair by damaging the cuticle and increasing copper uptake.

This study found that coconut oil impedes hair hydration more effectively than soybean oil by penetrating deeper, and suggested a new model for intermediate filament assembly in hair.

This study found distinct localization patterns of S100 family proteins in hair follicles, suggesting their differential roles in normal hair follicle physiology.

This study found that torsional measurements can effectively distinguish the effects of hair care products on the cuticle versus the cortex of hair fibers, unlike tensile measurements.

This article explores the structure of mammal body hair and the challenges in explaining its evolutionary origins, reporting no new empirical findings.

This study reports a good correlation between the curvature of human eyelashes and the displacement of the neutral axis, influenced by the non-uniform thickness of the outer cuticle layer.

Hair proteins change location and structure as hair cells mature.

This study found that perming and bleaching hair result in different distributions of cysteic acid, suggesting distinct damage mechanisms between the two treatments.

This study using an apertureless scanning near-field optical microscope found that dye restricted to hair's periphery remains mainly on the surface and in the endocuticle.

This review discusses the lipid composition of human hair across ethnic types, effects of damage on lipid content, and associated changes with diseases, but reports no new findings; further research is needed.

This study found that hydrogenated palm oil effectively conditions damaged hair by preventing water-induced swelling, with TOF-SIMS analysis showing that its component tripalmitin penetrates the hair's cuticle and outer cortex.

This study found that using henna dye positively affected hair cuticula pattern and diameters compared to undyed hair, though the degree of change may vary based on hair phenotype and condition prior to treatment.

This study found that CMAD wool keratin may protect human hair from damage during repeated bleaching and permanent waving treatments.

This study found that chemical hair straightening significantly reduced hair curl and improved smoothness and shine, but did not significantly affect transverse fissures or split ends, indicating potential benefits with some side effects.

This study identified two types of calcium in human scalp hair shafts: easily removable calcium, likely as calcium soaps, and more stably bound calcium, possibly related to Ca-binding proteins.

This study found that UV stabilizers must diffuse uniformly and in high uptake levels throughout hair fibers during humidification cycles to effectively prevent photo-oxidative degradation.

This study found that using a high-viscosity, high-amine-content silicone fluid as a pretreatment can protect hair from bleaching and dyeing damage without affecting these processes.

This study provides conclusive evidence of exogenous calcium fatty acid deposits forming between the cuticle layers in hair, affecting its optical and mechanical properties.

This article reviews the complex structure and molecular composition of hair keratins, highlighting their self-assembly process and implications for keratin extraction techniques, but reports no new experimental results.

This study found that the 16th-century mummified hair from a female mummy in Paju was remarkably well-preserved, with the hair's ultrastructural features maintained likely due to a calcium-rich surface coat.

This study found that DNA is present at low levels in human hair shafts, with higher amounts near the root, and that its levels decrease after surfactant washing and colorant treatments.

This study found that treating hair with a 1% cotton honeydew extract improves smoothness and reduces chipping compared to untreated hair, confirmed by clinical and SEM evaluations.

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.

This study found that shikimic acid- and maleate-based hair repair agents modified the structure of hair fibers, though they did not increase disulfide bridge content in the hair cortex.

This study analyzed how oxidative hair dye leaches from pigmented and nonpigmented hair during wash cycles, finding that melanin influences the dye deposition and leaching processes.

This study found that using a plasma hairdryer for 90 minutes caused significantly less hair damage, such as cuticle cracks or layer separation, compared to traditional hot air dryers.

This study found that patients with frontal fibrosing alopecia had significantly more titanium-containing nanoparticles in their hair compared to healthy controls, suggesting a potential environmental influence.

Frequent hairdryer use may worsen hair fragility in people with Pili Annulati.

Elkonyxis, a rare nail condition, improved when patients stopped their nail-picking habits.

This study found that hair from ovarian teratomas shares similar chemical composition and morphology with scalp hair, but differs in physical properties and cysteic acid bands.
