This study found that male and female hair specimens show structural differences, with female hair having a brown color at the distal end and smooth surface texture, while male hair is completely black and shows surface irregularities; these differences may aid forensic analysis.

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 article reviews hair analysis for drug detection and its applications in various fields, but reports no new research findings, emphasizing the need to consider the method's complexities and potential pitfalls.

This review describes how liver and kidney diseases and diabetes may affect ethyl glucuronide levels in hair, impacting forensic and clinical interpretations, but reports no new experimental results.

In this research, sequencing the chloroplast genomes of 10 Sansevieria trifasciata cultivars allowed the identification of a trnT-psbD deletion marker capable of distinguishing closely related species, and highlighted evolutionary links with Dracaena, contributing molecular tools for taxonomy and phylogenetic studies in Asparagaceae.

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 review discusses the factors influencing human hair color, including genetic components and enzymatic activity, and highlights the forensic significance of hair color analysis, but reports no new findings.

This study explored a multidimensional approach to examine body hairs' physico-chemical properties, potentially supporting their use over scalp hairs in forensic and intoxication studies.

This study characterized the hair follicle patterns of Indian bison, Black buck, and Nilgai, providing valuable data to help identify these endangered species' skins, commonly targeted by poachers.

This review discusses the properties and extraction methods of keratins from natural fibers and highlights their promising applications in fields such as biomedicine, bioengineering, and forensic science, but reports no new experimental results.

This review discusses the role of the MC1R gene in human pigmentation and its genetic variants, reporting no new results; the authors highlight its forensic applications for phenotypic prediction.

This study found that the PLEE method increased hair protein extraction efficiency threefold and that bleaching hair reduced the coverage of keratin and associated proteins, leading to poorer hair quality, though it did not affect the overall protein identification.

This study found that a genetic model using SNPs can predict early-onset male-pattern baldness with moderate accuracy, which may assist in decisions about interventions.

This study reports two cases of fatal metformin intoxication with hair concentrations significantly higher than those in subjects under treatment, marking the first use of hair analysis for such cases.

In this case study, a 3-year-old with tinea capitis achieved complete resolution following treatment, highlighting hair salons as potential indirect transmission sites for infection and emphasizing trichoscopy's diagnostic value when traditional signs like Wood’s lamp fluorescence are missing.

This biographical abstract highlights George Rogers' pioneering contributions to the understanding of keratin molecular structure and keratinisation biochemistry, including the application of electron microscopy to hair ultrastructure and the discovery of enzymes and gene transcription processes relevant to keratin proteins.

This study used proteomic profiling to reveal significant individual and site-specific differences in human hair shaft proteins, which may improve the differentiation of hair based on ethnic origin and individual identity.

The ProScope HR is an effective, user-friendly, and affordable tool for diagnosing hair loss.
