research Fine structure and immunocytochemistry of monotreme hairs, with emphasis on the inner root sheath and trichohyalin‐based cornification during hair evolution
Monotreme hair structure and protein distribution are similar to other mammals, but their inner root sheath cornifies differently, suggesting a unique evolution from reptile skin.
research K25 (K25irs1), K26 (K25irs2), K27 (K25irs3), and K28 (K25irs4) Represent the Type I Inner Root Sheath Keratins of the Human Hair Follicle
K25, K27, and K28 are found in all inner root sheath layers of hair, while K26 is only in the cuticle.
research Integral hair lipid in human hair follicle
Human hair has a protective lipid layer that can be damaged by moisture and treatments, affecting hair growth and health.
research Structural analysis of the outermost hair surface using TOF-SIMS with gas cluster ion beam sputtering
The hair's outermost surface has multiple layers of lipids and proteins.
research Pattern of expression of c-Myc, Max and Bin1 in human anagen hair follicles
c-Myc, Max, and Bin1 help hair follicle cells mature and die.
research Fine structure of marsupial hairs, with emphasis on trichohyalin and the structure of the inner root sheath
Marsupial hair structure and keratin distribution are similar to placental mammals.
research Recognition of the ultrastructure of the hair follicle of Cashmere goats under the transmission electron microscope
Recognizing ultrastructures of cashmere goat hair follicles helps identify and locate follicle layers.
research Evaluation of Changes and Characteristics of Hair According to the Application of the Hair Dryer Plasma Functional Module
Plasma hairdryers cause less hair damage than regular hot air dryers.
research An Electron Microscopy Study of Keratin Degradation by the Fungus Microsporum gypseum in vitro
Microsporum gypseum fungus breaks down keratin in hair by digesting it enzymatically, starting with less keratinized parts.
research Integral Lipid in Human Hair Follicle
The lipid in human hair follicles acts as a barrier, similar to the skin's lipid layer.
research Abnormal inner root sheath of the hair follicle in the loose anagen hair syndrome: An ultrastructural study
Loose anagen hair syndrome is caused by structural abnormalities in the hair follicle's inner root sheath.
research Epithelial barrier function: assembly and structural features of the cornified cell envelope
The cornified cell envelope forms a protective barrier in skin and hair, using specific proteins and lipids to maintain effectiveness.
research Some electron microscope observations on hardening in the human hair follicle
The hair follicle structure is more complex than thought, with new findings on protein formation.
research A highly resistant structure between cuticle and cortex of human hair
A tough membrane between the outer and inner layers of human hair protects it from damage.
research A Raman spectroscopy investigation of the resilience of hair cuticular scales under uniaxial stress
Hair cuticles remain stable and resilient under stress due to strong protein content and crosslinking.
research Facile and Efficient Enzymatic Methods for Harvesting or Removal of Cuticle Cells from Human Hair Shafts
The conclusion is that new methods for isolating hair cuticle cells and removing the cuticle layer are effective and convenient.
research Characterization of the Human Hair Shaft Cuticle–Specific Keratin-Associated Protein 10 Family
KRTAP10 proteins help form the hair shaft's tough outer layer by interacting with specific hair keratins.
research Formation of surface membranes in developing mammalian hair fibres
Mature hair surfaces are formed by keratinized cells with developed layers, not just modified plasma membranes.
research Ultrastructural aspect of the keratinolytic activity of piedra.
Piedraia hortae fungi dissolve both the outer and inner layers of hair.
research Distribution of Glycolipid and Unsaturated Fatty Acids in Human Hair
Human hair has more unsaturated fats inside than on the surface, and certain lipids may help bind the outer and inner layers together.
research Hard X-ray Microscopic Images of the Human Hair
High-resolution x-ray images showed three main structures in human hair: medulla, cortex, and cuticle.
research The cracking of human hair cuticles by cyclical thermal stresses
Frequent blow-drying causes cracks and breakage in hair cuticles.
research A highly resistant structure between the cuticle and the cortex of human hair. II . CARB , a penetration barrier
CARB is a strong barrier in human hair that prevents dye penetration.
research Analyzing the laser-light reflection from human hair fibers Part1: Light components underlying the goniophotometric curves and fiber cuticle angles
Hair color affects light reflection, with black hair having higher cuticle angles and lighter hair showing less specular reflection.
research Fermented grapeseed oil repairs chemically damaged hair via enhanced permeability mechanisms
Fermented grapeseed oil effectively repairs and protects chemically damaged hair.
research Hair
Hair analysis can detect drug use but is costly and interpretation is complex.
research Distribution and Localization of Hydrophobic and Ionic Chemical Groups at the Surface of Bleached Human Hair Fibers
Bleaching hair removes its protective top layer and exposes more hydrophilic groups, changing its chemical surface and affecting how it interacts with products.
research Physical Properties of Human Hair. 1. Evaluation of Bending Stress by Measuring the Major and the Minor Axis of Human Hair.
The cuticle significantly contributes to hair stiffness, making up about 60% of the total bending stress.
