In this study, researchers observed that cosmetic peroxide bleaching causes oxidative damage and protein loss in human hair, not only affecting the cuticle but also deeper cortical structures, correlating with bleaching severity.

This study used advanced analytical techniques to reveal that proteins and lipids are distributed unevenly in hair, with distinct structural differences depending on their location within the fiber.

This study found that at pH 9.0, CYS penetrated less and caused less damage to virgin human hair than TG because it barely reached the cortex region.

This study observed that lipids in human hair accumulate in specific areas and do not significantly impact water permeability, highlighting the utility of AFMIR for studying complex biomaterials.

This study found that human hair exhibits significant deformation in its intermediate filaments under strain, with recovery taking about 1000 minutes, suggesting a self-healing period post-mechanical stress. Additionally, cuticle scales deform much less than the cortex, and the Poisson ratio aligns with soft matter properties.

This study suggests that TGase 3 may contribute to hair fiber scaffolding by forming specific isopeptide bonds between keratin intermediate filaments and keratin-associated proteins.

This study examined the cytodifferentiation stage of hair follicle development in cashmere goats, identifying nine cell populations and key regulatory pathways, including transcription factors and keratin genes, that may influence fiber quality and inform breeding strategies.

This study cataloged human type II hair keratins, detailing their expression and differentiation roles in hair follicles and comparing them with type I keratins to explore keratin-pairing principles.

This study found that rhodamine B penetrated human hair fibers more effectively from an aqueous solution compared to a methanol/ethanol solvent, with penetration depending on hair morphology.

KRTAP10 proteins help form the hair shaft's tough outer layer by interacting with specific hair keratins.

In this study, researchers used scanning electron microscopy to analyze hair damage from 3% hydrogen peroxide and UVB radiation, observing that Caesalpinia sappan hair tonic formulations coated and interacted with the hair cuticle, potentially modifying hair fiber damage.

This study demonstrates that a bioinspired peptide, PepACS, can efficiently and safely perm hair by interacting with keratin's sulfhydryl group without compromising tensile strength, and it shows potential for hair repair and dyeing applications in the hair care industry.

This study found that Keratin 26 is expressed differently in hair follicle phases, particularly during catagen and telogen, influencing cashmere growth and interacting antagonistically with the BMP signaling pathway.

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.

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

This study found that modern styling cosmetics can significantly alter hair structure through changes in interfacial chemistry and cohesion, particularly when applied to already damaged hair.

This chapter reviews hair anatomy, hair shaft structure, and various cosmetic treatments that can alter or damage hair, but it presents no new research findings.

This study found that keratin derivatives with functionalized thiol groups improved binding to both natural and bleached hair fibers, suggesting a promising strategy for enhancing keratin's durability in hair repair.

This study found that heating damages Asian black male and female hair cuticles without altering their structure, with damage severity increasing at higher temperatures and longer exposure times.

This notice states that the article has been withdrawn due to the journal's transfer to a new publisher and reports no research findings.

This study employed a laser-based method to analyze how light reflection patterns vary on human hair fibers, revealing changes related to hair color and the tilt of the cuticle cells.

This study found that reducing BMP signaling in mouse nipple epithelia, achieved through Noggin overexpression, can convert them into hairy skin with pilosebaceous units.

This study found that moisture sorption properties of wool and hair fibers from various animals were similar, despite different structural features, with sorbed water being more ordered than liquid water.

In this study, researchers identified three molecules in hair that varied with age, suggesting potential markers for aging and targets for cosmetic products.

This in-vitro study reported that a luliconazole-based formulation improved hair cuticle integrity and was more effective than ketoconazole in repairing damaged hair after 5 and 10 washes, with sensory analysis supporting these results. Further human studies are needed to confirm its clinical effects.

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 article describes how PESCADOR software assists in creating detailed biological pathway charts from PubMed abstracts, focusing on hair and breast development case studies without providing new clinical results.

This review discusses the use of cosmetic nanocarriers to improve hair appearance and reports no new experimental results.

This review discusses in vitro methods for evaluating the effects of hair care products on hair fibers, reporting no new results; the authors emphasize the importance of selecting appropriate and accurate equipment for testing.

This article examines the role and composition of integral hair lipids in forming a protective barrier similar to the skin's epidermal lipid layer and reports no new findings about their effects.
