This study observed that mice with a Cx43 mutation exhibited slower and asynchronous hair regrowth with severe cuticle weathering, mimicking aspects of hair phenotype in some ODDD patients.

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 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 found that inhibiting arachidonate 12-lipoxygenase (ALOX12) may enhance hair cuticle maturation by increasing S100A3 protein citrullination and promoting cuticular differentiation in isolated human hair follicles.

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.

In this study, researchers used SEM/SDD-EDS to identify waterborne minerals like calcium and aluminum in the scalp hair cuticle of individuals using treated or untreated water for hair washing, finding that prior application of coconut oil or conditioners can prevent calcium uptake.

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 after four weeks of daily use, the roughness of the hair surface significantly decreased, as shown through quantitative image analysis using HIROX.

This study discovered a new region in the hair cortex where intermediate filaments are both aligned with the hair's axis and orientationally ordered, influenced by the cuticle boundary.

This article reviews the role of adult stem cells in tissue homeostasis and wound repair, focusing on their regulation within the murine hair follicle's specialized niche, but it presents no new findings.

This study used rapid-freezing immunocytochemistry to successfully map the ultrastructural localization of hair keratins in human scalp hair, primarily finding them in macrofibrils in the cortex and endocuticle.

This study found that keratin 6hf, a type II keratin, is expressed in specific regions of mouse and human hair and suggests potential interactions with keratin 17, impacting hair development and associated disorders.

Human hair's ability to get wet is complex and can change with treatments, damage, and environment.

This study demonstrates that spatially resolved IR and Raman imaging can effectively reveal the molecular structure and composition of untreated human hair, providing insights into its chemistry and structural integrity.

Keratin patterns in hair follicles help understand hair growth and potential hair and nail disorders.

This study identified significant differences in medullary structure, hair length, and root diameter among dorsal guard hairs of red foxes, golden jackals, and gray wolves in Turkey.

Laser treatment followed by a special hair growth solution increased hair count and thickness without side effects.

This study found that hair fibers broke down and lost keratin in extremely basic conditions, revealing the inner medulla and changing the color of the fibers.

This study found that disrupting the Sox21 gene in mice led to progressive hair loss and regrowth, identifying Sox21 as a key regulator of hair shaft cuticle differentiation.

This review discusses the use of cosmetic nanocarriers to improve hair appearance and reports no new experimental results.

This review explains the mechanical composition and molecular interactions that determine hair's mechanical properties, without providing any new experimental findings.

This study found that unsaturated fatty acids are more abundant in the cortex of human hair than on its surface, and steryl glycoside-like lipids may help bind the cuticle to the cortex.

This study found that thermal hair-straightening devices significantly damaged the cuticle and cortex of virgin Asian and Caucasian hair, with Asian hair experiencing more protein loss than Caucasian hair.

The study found that a polymer treatment changes the charge on hair surfaces, making bleached hair smoother and less porous.

This study found that white hair fibers have lower lipid content and different water absorption dynamics compared to brown hair fibers, suggesting differences in their barrier functions.

This study in Hexi cashmere goats found that secondary follicle activity increases with time, and Hoxc13 expression varies significantly across different growth stages, suggesting a role in follicle activity.

This study found that involucrin likely plays a key role in forming the cornified material of the medulla and inner root sheath of human hair, contributing to its mechanical strength.

This review discusses the evidence for a cause-and-effect relationship between scalp condition and hair condition, and reports no new clinical results from trials.

This study found that an enzymatic method effectively identified chemical treatments like perming and dyeing by detecting higher degradation in treated hair compared to untreated hair.

The book discussed in this abstract is a comprehensive guide to hair analysis, detailing the latest methods and applications across various fields such as toxicology and drug monitoring, designed for both newcomers and experts in the field.
