This study found that in naturally curved human scalp hairs, distinct arrangements of cell types on either side of the hair fiber contribute to its curvature.

This article reviews the challenges in studying keratin proteins and emphasizes the potential of modern proteomic techniques to advance their research, but it reports no new findings.

In this study, researchers identified a putative ovine KAP24-1 gene in sheep, revealing four unique DNA sequences with some similarity to KRTAP24-1 sequences from other species.

This research examined the ultrastructure of deer hair fibers and found significant variations in diameter, cuticle thickness, and intermediate filament arrangements among different fiber types.

In this study, researchers mapped cysteine accessibility in wool keratins and KAPs, revealing that certain cysteines in keratin end domains and Types I and II rod domains are accessible and likely involved in forming disulfide bonds.

This review explores the biology of wool follicles and suggests their potential use as research models in modern biology, but it reports no new findings.

This study introduces a modular fiber model to investigate how changes in microstructural properties of wool affect its critical buckling load, highlighting potential uses and areas needing further research in wool fiber biophysics.

This study suggests that β-catenin plays an important role in wool follicle development in transgenic sheep by enhancing the expression of keratin protein genes.

This study suggests that human keratin fiber matrix has a well-defined nano-scale grainy structure rather than being amorphous, with grain size influenced by chemical treatments, temperature, humidity, and follicle-level factors.

This study presents computational modeling and experimental analysis of the HGT protein KAP8.1, identifying key structural features that may influence hair's response to environmental conditions.

This study found that CMAD wool keratin may protect human hair from damage during repeated bleaching and permanent waving treatments.

Merino wool fibers change shape with moisture, while human hair shape stays the same.

In this study, the authors concluded that a hydrolyzed eggwhite protein treatment promoted the reconnection of disulfide bonds in excessively bleached hair, after reduction and oxidation processes in permanent waving.

In this study, topical application of keratin extract from wool promoted hair growth in mice by reducing the time for initiation and completion of growth phases and improving hair quality.

This article discusses themes in the molecular structure of hair and reports no new research findings.

This study found that mutations in certain keratin genes significantly affect wool traits in Chinese Merino sheep, suggesting these genes could be important for sheep breeding to improve wool quality.

This study found that Super Merino sheep have a higher wool follicle density, finer fleece, and distinct gene expression compared to Small Tail Han sheep, which may inform future breeding and genetic interventions.

This study reveals that overexpression of Wnt3 in transgenic mouse skin leads to a short-hair phenotype and cyclical balding due to structural defects in hair shafts, highlighting a role for WNT signaling in hair growth regulation.

This chapter reviews the complexity of hair and wool follicle formation, emphasizing the importance of cytological studies to understand the relationship between cellular components.

This review classifies mutant mice with hair abnormalities into six categories, providing an annotated table that serves as a reference for understanding the molecular controls of hair growth.

This review presents updated tables of mouse mutants with hair growth abnormalities to aid in understanding the molecular mechanisms of human hair disorders, but reports no new clinical results.

This study found that permanent waving treatment induces structural changes in the cortex proteins of white human hair, significantly reducing its tensile strength without altering the S-S band intensity.

This study found that xylanase and pectinase enzymes clean wool and specialty hair fibers as effectively as soap, without causing physical damage, whereas resinase was not effective.

This study found that excessive heat caused the most significant structural changes in hair from Caucasian and Afro samples, especially when combined with other treatments like bleaching and straightening.

This study discovered a new region in the hair cortex where intermediate filaments are both aligned with the hair's axis and orientationally ordered, influenced by the cuticle boundary.

This article reviews the impact of UV radiation and visible light on human hair structure and summarizes protective strategies, reporting no new clinical results.

In this study, researchers observed that mice with the naked gene showed frequent absence of hair cuticle and cortical cells during follicle growth, with abnormal keratin deposition also noted.

This study analyzes the fine structure and protein distribution in monotreme hairs, finding similarities with other mammals and detailing unique immunocytochemical features in their inner root sheaths.

This study used single-cell RNA sequencing to map the cellular composition of sheep hair follicles, revealing differentiation pathways and potential molecular mechanisms for wool curvature, which may inform sheep breeding.

This study found that coconut oil impedes hair hydration more effectively than soybean oil by penetrating deeper, and suggested a new model for intermediate filament assembly in hair.
