This study found that melanin extracted from cuttlefish ink provided significant protection against UV radiation damage to human hair, suggesting its potential as a photoprotective agent in hair-care products.

This study found that rare damaging variants in the KRT82 gene, which affect hair shaft integrity, may contribute to the risk of alopecia areata.

This study demonstrates that Rac1 activity is essential for normal hair follicle formation but influences hair structure and pigmentation, in terminal differentiation, through alterations in hair shaft, cuticle, and pigmentation organization.

This study found that the structure and mineral content of dromedary camel hair, specifically the medulla patterns, medulla index, and elemental composition, change with age, revealing differences among camels aged 1 year, 3-5 years, and 8-10 years.

This study investigated the hair structure of wild pigs in the Balıkesir region using stereomicroscopy and scanning electron microscopy, finding distinct bifurcation patterns, but concluded that pig bristles used in brushes likely wouldn't retain these features, complicating species identification.

This study observed that hair cuticles experience greater water-induced plasticization than hair cortex, affecting the torsional rigidity of hair fibers, which may help predict hair setting behavior.

This anatomical study on Eclipta alba concluded that unique secretory structures in stems and leaves may serve as identifying features of the plant and the Asteraceae family.

This chapter reviews hair anatomy, hair shaft structure, and various cosmetic treatments that can alter or damage hair, but it presents no new research findings.

This study concluded that bleach treatment partly transforms the hydrophobic top layer of human hair cuticles into a hydrophilic surface with clustered cysteic acid, visualized at the nano-scale using dynamic Chemical Force Microscopy.

This study observed that during male silkmoth development, trichogen cells in olfactory sensilla undergo significant membrane recycling, contributing to sensillum structure formation in a precisely timed series of stages.

This study found that monounsaturated oils like olive oil penetrate hair fibers effectively, whereas polyunsaturated oils typically do not penetrate beyond the cuticle.

This study investigated the hair of German shepherd dogs, revealing variations in color, shape, and band patterns across different body regions, while all hair types shared similar anatomical structures such as continuous, vacuolated medullas and cuticular scales with smooth or rippled margins.

In this study, the novel thiol-Michael click perming molecule, MA2-CySS, achieved repeatable perming with reduced oxidative damage, preserving hair keratin's structure while maintaining efficiency comparable to traditional oxidative methods.

This study examined the thermal conductivity of human hair using the Modified Transient Plane Source method, highlighting how frequent thermal, mechanical, and chemical treatments can damage hair by weakening its structure, particularly through changes in keratin that reduce elasticity.

In this study, researchers used the Modified Transient Plane Source method to measure the thermal conductivity of human hair, highlighting that common heat treatments can damage hair structure by altering its protein composition, emphasizing the importance of understanding thermal properties to mitigate such damage.

This study found that wool felting in Ukrainian Carpathian Mountain sheep is linked to significant changes in fatty acid composition, particularly highlighting a decrease in 18-methyleicosanoic acid in bound lipids, suggesting it as a potential marker for cuticle lipid layer damage during felting.

In this study, researchers found that hair fibers exposed to bleaching and UV irradiation displayed significantly more damage, including increased adhesion and surface heterogeneity, compared to untreated hair, highlighting a synergistic degradation pathway affecting the hair cuticle's integrity.

Polisorbate 20 is not suitable for curl creams due to instability.

TG5 helps maintain hair follicle health, while TG3 aids in hair shaft development.

This study suggests that ATR-FT-IR spectral analysis of hair fibres may detect breast cancer through increased lipid content changes linked to cancer presence.

This article reviews monilethrix, a rare genetic hair disorder causing brittle hair and alopecia, and emphasizes the need for clinical diagnosis and characteristic tricoscopic findings.

In this study, researchers identified the c.296C>T (p.T99I) variant in the KRT32 gene, which co-segregates with loose anagen hair syndrome, and found it decreases binding affinity to KRT82, potentially weakening hair anchorage.

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

This study found that at pH 9.0, CYS penetrated less and caused less damage to virgin human hair than TG because it barely reached the cortex region.

This study found that hair membrane fluidity is low in the cuticle but high in the cortex and medulla, with treatments like ionic surfactants and oleic acid increasing fluidity in hydrated hair; however, dehydration significantly reduces fluidity throughout the hair.

This study found that excessive heat caused the most significant structural changes in hair from Caucasian and Afro samples, especially when combined with other treatments like bleaching and straightening.

This study presents computational modeling and experimental analysis of the HGT protein KAP8.1, identifying key structural features that may influence hair's response to environmental conditions.

This article discusses themes in the molecular structure of hair and reports no new research findings.

This in-vitro study reported that a luliconazole-based formulation improved hair cuticle integrity and was more effective than ketoconazole in repairing damaged hair after 5 and 10 washes, with sensory analysis supporting these results. Further human studies are needed to confirm its clinical effects.

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.
