This study found that human hair cuticle and cortex have different protein structures, with beta-sheet and disorder configurations in the cuticle and alpha-helical structures in the cortex.

This study reported that fibrosing alopecia in a pattern distribution can occur in patients of color, with clinical and histopathological features allowing for an accurate differential diagnosis.

In this study, D-OCT imaging revealed distinct structural and vascular changes in patients with frontal fibrosing alopecia, highlighting the technique's potential for diagnosing and monitoring the condition's activity.

This study reports that different animal species exhibit distinct hair scale patterns and elemental compositions, which can aid forensic investigations in identifying animal hair.

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.

In this study, the KPAI and KP-IGA scoring systems for assessing keratosis pilaris showed excellent interrater and intrarater reliability, offering standardized measures for clinical and research use.

In this study, researchers identified a gene expression pre-pattern and implicated the Wnt inhibitor Dickkopf 4 in the formation of color patterns in domestic cat embryos.

In this study, researchers found that the gene Dkk4 influences color pattern formation in domestic cat fetuses, and its mutation is linked to the Ticked pattern type.

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 reviews the genetic mechanisms behind cat coat patterns, revealing that specific loci determine tabby variations and suggesting these patterns could unravel broader developmental and evolutionary biology insights.

This study found that while molecular hair structures were nearly identical across individuals, genetic factors seem to influence specific lipid compositions, as seen in identical-patterned hair from parent-child pairs and identical twins, but not fraternal twins.

This study found that the DFS pattern occurs in about 28% of ANA-positive cases and is relatively frequent in autoimmune diseases, contrary to previous observations suggesting no link with these diseases.

In this study, researchers found a correlation between x-ray patterns and the element composition of human hair, with certain metal roles in the hair matrix considered.

This study found that hair root sheaths can be accurately typed for erythrocyte acid phosphatase, adenylate kinase, and adenosine deaminase, consistent with blood typing results from the same donors.

This study explored the potential of using isoenzyme detection after electrophoresis to characterize human hair, though no new clinical results are reported.

This study examined the dermoscopic features of five patients with tuberous sclerosis and found that dermoscopy can differentiate characteristic cutaneous features from similar conditions, potentially aiding in earlier diagnosis when other symptoms are subtle or absent.

This small study reports that a 6-group geometric classification method is more reliable for classifying human hair curl, although a digital system could further reduce errors.

This report describes the sonographic characteristics of a proliferating trichilemmal tumor in the subungual region, identifying it as a heterogeneous mass with echogenic foci, potentially representing keratin and cholesterol.

In this case study, a 36-year-old male with symptoms of keratosis pilaris atrophicans faciei and frontal fibrosing alopecia tested negative for a specific mutation, highlighting genetic testing's potential to improve diagnosis and treatment outcomes in these similar conditions.

This report presents four new cases of follicular porokeratosis, which exhibit distinct histological features where the cornoid lamella are confined to the follicular ostia.

This study found that miniaturization of hair is present in some women with androgenetic alopecia, but diagnosis may also be based on differences in hair shaft diameter between scalp regions.

Hair feels different when touched and rubs together in various ways.

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.

In this study, researchers found that the shape of polygonal domains, such as squares and triangles, significantly impacts Turing pattern formation, with domain geometry affecting the stability and type of bifurcations observed in simulations.

Hair loss in male frontal fibrosing alopecia may spare areas covered by a wristwatch.

This study in Chennai, India, found that while some trichoscopic patterns are specific, many overlap across different scalp dermatoses, highlighting the importance of dermatologists staying informed about the latest findings.

This study highlights how examining hair histology under a microscope helps forensic analysts identify animal species by distinguishing specific microscopic features, which supports accurate reference database creation and aids crime scene investigations.
