This study reports that hair analysis could potentially monitor metformin use in diabetic patients, suggesting a possible correlation between daily dose and concentration in dark hair but not in light hair.

This review discusses advancements and gaps in using proteomics for hair testing and its potential in developing a medical proteome repository, but reports no new research findings.

This paper outlines the structural and forensic significance of human hair, discussing its role in personal identification, drug exposure documentation, and evaluating its utility and limitations as forensic evidence without presenting new research findings.

In this study, Thai scalp hair exhibited some age and sex variations in hair area, which may aid forensic and anthropological investigations.

This study concluded that drug-distribution measurements using micro-segmental hair analysis are effective for drowned bodies, as natural water containing divalent ions prevents drug washout from hair.

This article reviews the use of hair analysis in forensic and environmental toxicology for detecting potentially toxic elements and drugs, but it reports no new research findings.

This study found that using a microscope can effectively distinguish between human and animal hair based on microscopic characteristics, making it a critical tool in forensic investigations.

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 found distinct sex-based differences in the microscopic characteristics of scalp hair among a Nigerian population, providing valuable forensic data specific to this group.

This review discusses the current state of research on genetic markers for predicting human phenotypic traits from DNA samples for forensic purposes and reports no new experimental findings.

This review discusses the increasing importance of hair analysis in forensic toxicology and highlights the complexities in interpreting results due to external contamination and regional collection differences, but reports no new findings.

This study found that hair dyes significantly affect DNA sequence analysis, with the organic extraction method performing better on hair shafts and the prepFiler kit yielding higher success for follicle-included samples.

This study found that hair shaft keratin proteins can be reliably identified from samples as small as 0.12 cm, suggesting their potential forensic utility with typical casework sample sizes.

This study demonstrated that genetic markers can predict human ear morphology with moderate to good accuracy, potentially aiding forensic identification in crime scene investigations where traditional DNA matches are unavailable.

In this study, researchers found that massively parallel sequencing of mitochondrial DNA (mtDNA) can improve information recovery from forensic samples, with successful full region amplification possible from as few as 2,000 mtDNA copies, albeit with variability in heteroplasmy among hair samples from the same donor.

This review highlights how the development of forensic DNA phenotyping systems like IrisPlex, HIrisPlex, and HIrisPlex-S has advanced criminal investigation by accurately predicting physical traits such as eye, hair, and skin color from DNA, thereby improving the precision and relevance of forensic applications.

This study suggests that degraded human hair shafts are highly resistant to contamination by exogenous DNA, making them a valuable source for forensic and ancient DNA analysis.

This study developed a new STR typing strategy for forensic casework, enabling the simultaneous analysis of 11 polymorphic systems, particularly useful for limited or degraded DNA samples such as telogen hair roots.

In this study, researchers used proteomics to analyze hair samples from diverse ethnic populations, finding that hair protein profiles could potentially distinguish individuals based on ethnicity, sex, and age, offering a new method for human identification in forensic science.

This study reported that acute thallium poisoning, investigated through three forensic cases involving both intentional and accidental overdoses, resulted in severe symptoms including neurological damage, multiple organ failure, alopecia, and, in two cases, death, emphasizing the extreme toxicity of thallium compounds.

This review examines the role and significance of next-generation sequencing technologies in forensic identification and other forensic applications, but reports no new findings.

This study used electron microscopy to characterize tissues on telogen hair roots, finding that tissue quality, including nucleated and nonnucleated epithelial cells, may play a crucial role in DNA typing for forensic analysis.

This article reviews the rationale and science behind forensic hair examinations and discusses the role of microscopic and DNA techniques in differentiating hair sources but reports no new findings.
