This study found that a new 3D image analysis method from SEM images enables quick and accurate measurement of cuticle scale heights in hair fibers.

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

This study found that hair proteome profiling and genetically variant peptide identification in hairs remained effective after an explosive blast, indicating potential for forensic human identification despite damage.

This study found that African and Caucasian hair contain the most lipids, and depletion of these lipids leads to less water retention and increased water desorption, with Caucasian hair showing improved breaking tenacity after lipid extraction.

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 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 Piedraia hortae invades and damages human hair by slowly degrading keratin in the cortex, which may contribute to the fungus's persistence and the chronic nature of the infection.

This study suggests that BLMP-1 is important for timely molting and oscillatory gene expression in C. elegans, indicating a potentially conserved mechanism for rhythmic skin regeneration.

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 discovered previously unknown structures in human hair shafts that may stabilize hair structurally and physicochemically.

This study used phase contrast hard x-ray microscopy to capture detailed images of healthy human hair, revealing distinct structures such as the medulla, cortex, and cuticular layer.

This study found that a proteomics-based approach can effectively distinguish between scalp and pubic hair by identifying unique protein signatures, providing a more quantitative and objective method for tracing hair contamination sources in GMP manufacturing and forensic investigations.

This study found that UV radiation exposure during a simulated Brazilian summer caused more significant mechanical damage to natural hair than bleaching, although both caused comparable structural alterations, with double bleaching leading to the most severe protein degradation.

In this study, researchers found that a high-cost hair restoration product containing coconut oil and glycerol effectively restored the structural integrity of chemically processed hair, particularly in samples that were significantly damaged by bleaching and color treatments.

Hair styling products can damage hair over time.

In this study, ultrastructural examination of hair in children treated with valproic acid showed a normal hair surface and cuticular pattern, despite reported hair changes with the drug.

A woman with Parry-Romberg syndrome developed new curly hair on one side of her scalp, a condition not previously linked to the syndrome.

This study found that permanent dye application causes initial swelling and subsequent degradation of the hair cuticle, with recovery taking more than 8 weeks to approach pre-treatment conditions.

In this study, researchers found that specific enzyme activities in young females' hair follicles were correlated with changes in hair shaft structure and properties, and permanent waving was associated with chemical changes that suggest hair damage.

This study reports an improved method for determining blood type from human hair using immunohistochemistry.

This study found that enzymatic conversion of Arg-51 in S100A3 protein to citrulline promotes homotetramer assembly, potentially increasing Ca²⁺ binding required for hair cuticular barrier formation.

This study found that the hairless mutant gene in C 57BL/6 mice affects the hair follicle cycle and leads to early thymus degeneration and distinct skin changes.

This study found that the use of high pH chemical agents for hair straightening can cause significant damage to hair, including protein degradation and weakened fiber strength, and may lead to permanent scalp conditions like contact dermatitis and cicatricial alopecia.

This study observed that hair follicle cuticular cells undergoing keratinization were significantly thicker than those in a normal hair shaft, due to incomplete loss of cytosol.

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

In this report, the author shares experiences from a six-month curricular internship, highlighting activities such as arterial pressure monitoring in a community pharmacy and addressing off-label rituximab use at a hospital, alongside discussions of hair loss treatments and nutritional supplementation for dysphagia in the elderly.

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.

This article discusses the use of atomic force microscopy for examining human hair surfaces in dermatology, cosmetics, and forensic science, but presents no new research findings.

This study consolidates information on the unique structural and functional biology of Indian hair, reporting distinct scalp microbial ecology and trichoscopic parameters, which are important for diagnosing and treating hair conditions in Indian populations.
