90-120 / 1000+ resultsresearch Expression of Novel Keratin-Associated Protein 5 Genes in the Cuticle Layer of Human Hair Follicles
The study found nine new hair protein genes in human hair follicles.
research Impact of Acid (Progressive Brush) and Alkaline Straightening on the Hair Fiber: Differential Effects on the Cuticle and Cortex Properties
Glyoxylic acid straighteners cause more protein loss but have similar hair strength effects as traditional alkaline straighteners.
research On Pathways for Small Molecules Into and Out of Human Hair Fibers
Dye enters hair at the edges of cuticle cells and penetrates more from water than alcohol-based solutions.
research Chronological Aging of Human Hair Keratin Fibers
Hair ages as the cuticle wears down, especially beyond 1 meter from the root, affecting its strength and shine.
research Local Structure of Human Hair Spatially Resolved by Sub-Micron X-Ray Beam
Human hair has a new region with ordered filaments and the cuticle contains β-keratin sheets.
research Influence of Oxidative and Reductive Treatment on Human Hair: Analysis of Hair Damage
Chemical treatments and daily stresses damage hair, especially the cuticle layer.
research Attenuated Total Reflection Fourier Transform Infrared Spectroscopy Analysis of Human Hair Fiber Structure
Human hair has different protein structures in its cuticle and cortex.
research A Study of the Differentiation Products of the Hair Follicle Cells with the Electron Microscope
Hair follicle cells become four types: medulla, cortex, cuticle, and inner root sheath.
research Photoaging of Hair Fiber and Photoprotection
Sunlight damages hair, causing cuticle loss, protein changes, and discoloration.
research Hair Morphology in Androgenetic Alopecia
Abnormal cuticle and hair shaft medulla cause hair loss in androgenetic alopecia; sonography helps diagnose and manage it.
research Cross-Linked Features of Mouse Pelage Hair Resistant to Detergent Extraction
Some mutant mice have hair with abnormal cross-linking, mainly in the cuticle, not affecting other hair parts.
research Physical Properties of Human Hair: Evaluation of Bending Stress by Measuring the Major and Minor Axis of Human Hair
The cuticle significantly contributes to hair stiffness, making up about 60% of the total bending stress.
research On the Correlation Between the Curvature of the Human Eyelash and Its Geometrical Features
Eyelash curvature is linked to the thickness of the cuticle layer at the root.
research Application of XANES Profiles to X-Ray Spectromicroscopy for Biomedical Specimens: Part II. Mapping Oxidation State of Cysteine in Human Hair
Perming and bleaching damage hair differently, with bleached hair having more cysteic acid in the cuticle.
research Scanning Electron Microscopy Approach for Evaluation of Hair Dyed with Lawsonia Inermis Powder: In Vitro Study
Henna dye improves hair cuticle and thickness but effects vary by hair type and health.
research Microstructure of Defective Mink Guard Hair
Defective mink guard hairs have split tips and missing cuticle cells, causing a metallic sheen.
research In-Situ Tensile Testing of Hair Fibers in an Environmental Scanning Electron Microscope
Hair fibers break by cuticle cell slipping, shape changing, cuticle fraying, and surface cracking when stretched under specific conditions.
research Cross-Linked Features of Mouse Pelage Hair Resistant to Detergent Extraction
Two mouse mutants have defective hair cuticle cross-linking.
research Arachidonate 12-Lipoxygenase Inhibitors Promote S100A3 Citrullination in Cultured SW480 Cells and Isolated Hair Follicles
Inhibiting ALOX12 can help hair cuticle maturation by increasing S100A3 citrullination.
