Different oils affect hair flexibility and strength, with their impact varying on whether hair is virgin or bleached.

This study suggests moving away from using rigid racial categorizations and outdated typologies in favor of analyzing detailed trait patterns, providing a foundation for future research on human variation and hair traits in relation to population affinity.

This study analyzed scalp hair proteins from healthy children and their mothers, finding that non-structural proteins could serve as promising biomarkers for understanding long-term developmental changes and health status linked to early childhood experiences.

This study explored the potential of human hair keratin as a filtration material, finding that it may effectively absorb the pollutants diclofenac and perfluorobutanesulfonate. The researchers reported significant binding affinities through molecular simulations, supporting further investigation into keratin's use for water purification.

This study evaluated the protective effects of a hair conditioner containing rice derivatives on natural Caucasian hair using various analysis methods and found that the conditioner, especially with rice germ oil GX-N, effectively improved hair properties even under stress conditions like irradiation.

In this study, researchers found that subjects with clinical alopecia had significantly higher levels of squalene in their hair bulbs compared to controls, suggesting squalene as a potential metabolic and pathogenic marker for certain alopecia conditions.

This study suggests that the curly hair phenotype in Mangalitza pigs may involve complex gene interactions related to calcium signaling and lipid metabolism, rather than changes in TRPM2 or CYP4F3 expression.

This review discusses the psychiatric approach to treating alopecia patients and highlights the interplay between psychological factors and hair disorders, but reports no new research results.

This review discusses the potential strategy of continuing topical minoxidil when starting low dose oral minoxidil to mitigate initial hair shedding in alopecia, but reports no new clinical results.

This review discusses the genetic and biological factors influencing hair curliness, revealing strong links to specific protein variations, and reports no new clinical results.

This study found that components derived from Sansevieria trifasciata demonstrated notable antibacterial activity against Escherichia coli and Streptococcus aureus, highlighting potential for developing new antibacterial agents.

This study reported that machine learning analysis of protein profiles in hair segments achieved high accuracy in distinguishing women with non-suicidal self-injury disorder from healthy controls, suggesting hair proteomics as a promising non-invasive biomarker for stress-related psychopathology with potential clinical applications.

This review covers the basic principles of forensic hair analysis, including how chemical substances get incorporated into hair, and emphasizes its applications in disease diagnosis, without providing new experimental results.

This study documented three cases of acute thallium poisoning—one involving accidental overdose and two linked to intentional homicide—characterized by neurological and systemic symptoms, and in severe instances, death, underscoring thallium compounds' significant toxicity.

This review reports that hair analysis can confirm drug exposure but not accurately estimate doses due to variability and confounding factors like melanin and cosmetic treatments, suggesting it should be used as a qualitative forensic tool rather than for precise dose quantification.

The book is a comprehensive guide for forensic practitioners and exam candidates.

This study presents a comprehensive forensic analysis that suggests the original inhabitants of the Americas, today classified as Black Americans, have been systematically reclassified to obscure their genetic heritage and sovereign identity, with evidence showing greater genetic affinity to Paleoamerican specimens than African ancestors.

This study presents evidence suggesting that populations now categorized as Black American are the original inhabitants of the Americas, with genetic heritage and identity obscured by historical reclassification to strip sovereign rights.

This study reports that Korean adolescents with androgenetic alopecia tend to have milder symptoms than adults and a higher prevalence of family history of alopecia.

This study found that both AB(0) antigens and keratin phenotype can be determined from the same hair fragment using specific protein extraction and analysis methods.

In this study, human hair-carboxymethylated protein analysis showed that weathering for over 2.5 years can obscure electrophoretic patterns, while cosmetic treatments did not cause significant changes.

This review highlights recent innovations in hair specimen analysis, discussing its applications in medical diagnostics, forensic science, and stress assessment while noting challenges such as hair growth variability and contamination that limit its current impact.

This study developed a sensitive method for assessing hair keratin stretch elasticity modulus, suggesting potential applications in forensic medicine.

This study found a genetic electrophoretic variant in high-sulfur proteins from human hair, which was more prevalent in the Japanese samples compared to Caucasian samples, suggesting an autosomal inheritance pattern.

The woman likely died from acute arsenic poisoning, not chronic exposure.

This study found significant hair regrowth in male pattern baldness using 2% and 3% topical minoxidil solutions compared to placebo over a 4-month period.

This study proposes a new, objective method to classify human hair into eight categories based on specific shape measurements, rather than traditional ethnicity-based classifications.

In this study, bleaching and perming were found to significantly reduce opiate concentrations in both spiked and naturally opiate-positive human hair samples.

This study successfully used ATR FT-IR spectroscopy to uniquely identify or differentiate human hairs by detecting specific spectral features associated with individual hair characteristics and cosmetic residues on hair surfaces.

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.
