This study introduced a new hair shading model that more accurately simulates light scattering on hair fibers, capturing effects not predicted by previous models.

This paper reviews the complex anatomy and development of human hair and emphasizes the need to understand these processes for interpreting drug incorporation into hair, with no new clinical results reported.

This study observed morphological changes in scalp hair follicles of humans deprived of protein for 15 days, which suggests potential use in diagnosing protein-calorie malnutrition.

This research retrospectively evaluated 92 skin specimens to propose histopathological criteria for diagnosing alopecia areata incognito, distinguishing it from telogen effluvium and androgenetic alopecia.

This study found that improved outcomes in scalp surgery were achieved by utilizing knowledge of the surgical anatomy of the scalp to avoid complications like unsightly scars and distorted hair patterns.

This review discusses various aspects of hair follicle biology and highlights unresolved questions and potential new research avenues, but presents no new experimental findings.

This study found that unsaturated fatty acids are more abundant in the cortex of human hair than on its surface, and steryl glycoside-like lipids may help bind the cuticle to the cortex.

Chemotherapy can cause significant hair thinning and changes in hair texture, while tamoxifen has a smaller effect.

This article discusses scalp tissue expansion as a superior reconstructive option for large defects over traditional skin grafts and flap methods, but reports no new clinical outcomes.

This review highlights that human hair is a valuable biological matrix for clinical and toxicological analyses, demonstrating its applicability in detecting various active substances from different pharmacological classes.

Understanding hair structure and growth is key for diagnosing hair diseases accurately.

This review discusses the expanding understanding of TRPV3's role in pain and skin pathology, while highlighting the need for further pharmacological research to fully resolve its functions.

This study found that Caucasian hair is destroyed more easily than Asian hair when stretched, as indicated by changes in secondary structure, disulfide bond breakage, and physical disintegration.

This article discusses how drug molecules integrate into hair fibers, focusing on biological transport mechanisms and physicochemical factors, but reports no new experimental findings.

This study presents the first detailed 3D models of the complete K1/K10 keratin dimer and identifies structural features and interactions that may inform understanding of keratin filament assembly.

This review explores the structure and development of the hair cuticle, highlighting difficulties in studying some aspects and proposing new experimental approaches, but reports no new clinical results.

Keratin structure changes during keratinization, but the exact model remains uncertain.

This review discusses the role of hair microscopy in diagnosing alopecia, stating that while it excludes diagnoses related to hair breakage, it only confirms nonspecific short anagen in alopecia cases.

This review discusses the impact of various external factors like cosmetics, traction, and radiation on hair health and color, but reports no new findings.

This study found that PGA-4HGF nanoparticles enhanced hair growth in mice more effectively than 4HGF alone by increasing anagen phase duration and dermal papilla cell proliferation.

This study found that L-cystine-modified rabbit hair fibers had improved dye adsorption and spinnability, due to changes in secondary structure and surface characteristics.

This chapter reviews the anatomy and structure of hair, discusses hair damage and analyses, and explores methods for processing hair changes, but presents no new research findings.

In this study, reducing agents like ammonium thioglycolate, L-cysteine, and sodium sulfite in shampoo effectively decreased hair flyaway and frizz without causing damage, as no critical hair damage was observed in structural and tensile strength assessments.

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 concluded that the process of mummification disfigures facial features, making identification challenging, but commercial shrunken heads retain more defining features compared to ceremonial ones.

In this study, disruptions in phospholipase A2 activity in Arabidopsis thaliana significantly impaired the plasma membrane localization of PIN proteins, affecting auxin transport and root development.

This review discusses the influence of oestrogens on various skin components and highlights their modulatory roles and receptor pathways, but it reports no new clinical results.

This case study of a cat with pancreatic carcinoma and paraneoplastic alopecia found that removing the internal tumor reversed hair loss, but symptoms reappeared as the cancer metastasized.

This study identified a novel keratin-associated protein, KAP24.1, which is specifically expressed in the human scalp and located in the hair cuticle.

This study sequenced and analyzed the goat skin transcriptome, revealing genes involved in signal transduction and cell communication that are differentially expressed during hair growth phases, providing insights for Cashmere goat breeding.
