This article describes the structure and components of hair cuticle cells and their intercellular junctions but reports no new clinical results.

This study discovered that the lipid in human hair follicles is mainly located in the hair cuticle and keratinized inner root sheath, distinct from sebaceous and epidermal lipids, suggesting a potential role as a "hair barrier.

This study found that the formation of the fibre cuticle surface in Merino sheep is similar to the epidermal stratum corneum process and not from a modified plasma membrane as previously thought.

This study reports that structural abnormalities in the inner root sheath of hair follicles may cause the hair shaft to be loosely attached in patients with loose anagen hair syndrome.

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.

The researchers developed a technique for processing and staining free hair samples using paraffin embedded blocks, revealing that routine staining does not color the enucleated cuticle, while the cortex and medulla show distinct colorations when stained.

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 observed distinct changes in the ultrastructure of Hexi cashmere goat hair follicles throughout the year, highlighting stages with specific cellular and structural characteristics.

This study found that specific human hair keratins are differentially expressed in the hair follicle, suggesting a shared pathway of epithelial differentiation between hair cortex and nail plate cells.

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 article discusses how drug molecules integrate into hair fibers, focusing on biological transport mechanisms and physicochemical factors, but reports no new experimental findings.

This study found that 3-aminopropyltriethoxysilane penetrates hair fibers and improves the mechanical resistance of dry hair, addressing the needs for increased body in fine hair.

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.

This article examines the role and composition of integral hair lipids in forming a protective barrier similar to the skin's epidermal lipid layer and reports no new findings about their effects.

This study found statistically significant patterns in hair morphology and ultrastructure linked to biogeographic ancestry among European, African, and East Asian populations.

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 analyzes the fine structure and protein distribution in monotreme hairs, finding similarities with other mammals and detailing unique immunocytochemical features in their inner root sheaths.

KRTAP10 proteins help form the hair shaft's tough outer layer by interacting with specific hair keratins.

In this study, researchers observed that mice with the naked gene showed frequent absence of hair cuticle and cortical cells during follicle growth, with abnormal keratin deposition also noted.

This study used ultrahigh-resolution optical coherence tomography to observe hair shaft structures, finding melanin granules absent only in white hair, which may explain color differences between black and white hair.

In this study, autophagy was commonly observed during keratinization in neonate rat hair follicles, suggesting lysosomal proteases and cytoplasmic enzymes may coordinate in hair follicle cell differentiation.

The study developed a hair cream using extracts from plants like Hibiscus rosa sinensis and Nigella sativa, reporting that it may protect the scalp and hair by providing antimicrobial effects, promoting hair growth, and preventing hair fall and graying.

Pollution exposure speeds up hair damage.

In this study, researchers found that a protein-enriched cream made from Spirulina platensis improved the physical structure of natural hair, as evidenced by more intact and smoother cuticles compared to a control cream without protein, suggesting its potential for hair care applications.

The document explains how hair is studied in forensics to identify its source and its role in criminal investigations.

This study utilized advanced imaging techniques to quantify hair damage and dye uptake dynamics, revealing that compound penetration in hair is influenced by molecule size and lipophilicity.

In this study, researchers found that neonate hairs have a distinct microstructure with no medulla and smaller hair follicles compared to adult hairs.

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.

This review explores the structure and development of the hair cuticle, highlighting difficulties in studying some aspects and proposing new experimental approaches, but reports no new clinical results.

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.
