This study found that keratin-associated proteins related to metallothionein and occludin appear in various animals, suggesting they may have roles beyond hair characteristics and were later adapted for hair production.

This study found that all examined biomarkers and clinical features were elevated in systemic lupus erythematosus patients, particularly ANA and Anti-dsDNA autoantibodies, but no single biomarker was sensitive or specific enough for diagnosis.

This study used in-lab hair samples to show that cut hairs found at a crime scene and on a suspect can be matched to confirm they were from the same individual.

In this study, researchers found that alopecia areata patients show a significant reduction in suppressive regulatory T-cells and an increase in inflammatory T-cell populations, suggesting an immunological imbalance contributing to the disease.

This article describes various hair and scalp examination techniques, including noninvasive, semi-invasive, and invasive methods, noting that trichoscopy is a simple, well-accepted, noninvasive technique for evaluating hair loss patients and monitoring treatment.

This paper discusses advancements in forensic hair analysis, emphasizing a novel DART–HRMS method that improves the accuracy and efficiency of detecting drug use timelines.

This study found that carbon and nitrogen isotope analysis of cattle hair reflects dietary and farm system differences, offering insights into cattle nutritional ecology and agroecosystem characteristics.

This study found that a cocktail of three proteins from embryonic skin can enable adult fibroblasts to regenerate hair follicles by altering gene expression and activating regenerative signaling pathways.

This study found that combining micro-needling, low-level laser therapy, and autologous non-activated platelet-rich plasma increased hair density in patients with androgenic alopecia over the treatment period.

This study found that higher concentrations of copper (II) ions in human hair increase protein oxidative modification, contributing to hair damage regardless of UV exposure and pigmentation level.

This review discusses long hair FUE, highlighting its appeal for those seeking discreet hair transplants and noting comparable graft survival and final outcomes to shaven FUE, but reports no new clinical results.

This study found that the structural and chemical composition of human curly hair may resemble that of sheep wool, implying a shared characteristic among mammals with wavy hair.

Hair growth is cyclic and influenced mainly by local factors.

This study identified 12 new genes associated with the hair follicle and various stages of the hair cycle in mice, which could lead to novel targets for hair growth or depilation therapies.

This study at B.J. Medical College and Civil Hospital highlighted an extensive range of nail disorders, with onychomycosis being the most common, and emphasized the importance of nails in diagnosing both dermatological and systemic conditions.

This study demonstrated that a daily oral supplement of 1000 mg Kera-Diet® improved hair and nail conditions in women experiencing acute telogen effluvium and brittle nail syndrome over three months.

In this study, researchers evaluated emulsions made with natural plant extracts and oils on guinea pigs, finding that a specific hydrophilic/lipophilic balance and globule size led to a stable emulsion and stimulated hair growth.

This review discusses potential causes of alopecia and hair overgrowth in pediatric patients, detailing diagnostic techniques and treatments, but presents no new research findings.

This thesis investigates the underlying mechanisms and treatment options for androgenetic alopecia, highlighting the molecular roles of androgens and genetic predispositions, and evaluates current and emerging therapies, such as PROTACs and Janus Kinase inhibitors, to enhance patient management.

KAP genes are crucial for hair development and show both shared and unique traits in humans, chimpanzees, and baboons.

This study found that two pre-Hispanic mummies from the Andean coast had well-preserved hair with significant amounts of heavy metals like iron, lead, bromide, and occasionally arsenic, revealing their historical context.

This study identified three genes in the ovine KAP13 family on chromosome 1 and found that a specific allele of KRTAP13-2 is associated with improved wool fibre diameter uniformity in Chinese Tan sheep, suggesting its potential use as a marker for enhancing wool traits.

This study identified a unique concentric double-layered structure in both Japanese and Caucasian SHINAYAKA hair, associated with improved flexibility and elasticity, and developed a succinic acid treatment to enhance these properties.

This study characterized a new human keratin, hK6irs1, specifically found in the inner root sheath of hair follicles, which suggests its role in the structural integrity and guidance of growing hair shafts.

This study found that a keratin mutation may cause diffuse partial woolly hair associated with loose anagen hair syndrome in some families, but other genetic factors could play a role in different cases.

In this randomized controlled trial, oral intake of the probiotic Latilactobacillus curvatus LB-P9 significantly improved hair luster, elasticity, and participant satisfaction in individuals with mild to moderate hair damage compared to placebo, without significant adverse effects reported.

In this study, grape seed oil was found to be the most effective herbal oil for improving gloss and reducing fractures in various hair types.

This study demonstrated that Wnt5a can serve as an orienting signal for mouse skin's planar cell polarity but its overexpression disrupts hair follicle orientation, which can be rescued by modifying Fzd6 levels.

This study analyzed the swelling behavior of human hair during permanent waving treatment, finding that both the microstructure and macrostructure of intermediate filaments swell simultaneously at the initial stage, and while partially destructed by reduction, they are considerably restored through oxidation.
