research The cell membrane complex: Three related but different cellular cohesion components of mammalian hair fibers
The cell membrane complex in mammalian hair has three distinct types with different structures and chemical properties.
research Scanning Electron Microscope Evaluation of Hair Dye Effects on the Cuticle Cells of Canine Hair
Hair dye can damage dog hair and cause health issues.
research Analyzing the laser-light reflection from human hair fibers. I. Light components underlying the goniophotometric curves and fiber cuticle angles.
The research found a way to measure hair surface changes by analyzing how light reflects off of it, and determined hair cuticle angles vary by hair length and color.
research A discrete transition zone between cuticle and cortex layers of a human hair fibre: changes observed in the presence of breast cancer
Breast cancer alters specific molecular structures in hair, which revert after cancer removal.
research Effects of conditioners on surface hardness of hair fibers: an investigation using atomic force microscopy.
Conditioners with PQ-10 soften the flat part of hair cuticles but harden the edges.
research A discourse on human hair fibers and reflections on the conservation of drug molecules
Hair analysis for drugs needs a better understanding of how drugs enter hair, considering factors like hair structure and pigmentation.
research In-Situ Tensile Testing of Hair Fibers in An Environmental Scanning Electron Microscope (ESEM)
Hair fibers break by cuticle cell slipping, shape changing, cuticle fraying, and surface cracking when stretched under specific conditions.
research Elucidating penetration pathways into the hair fiber using novel microscopic techniques.
The conclusion is that substances can penetrate hair fibers through multiple pathways, including both the cell membrane complex and the non-keratinous parts.
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 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 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 Morphology and ultrastructure of antler velvet hair and body hair from red deer (Cervus elaphus)
Antler velvet hair and body hair of red deer have different structures that help with protection and insulation.
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 Extractable substances from human hair: a discussion about the origin of the holes
Holes in mature hair are likely caused by the removal of substances during hair care.
research Photodegradation of human hair: a microscopy study
UV radiation significantly damages hair, especially with humidity, making it more vulnerable to further damage.
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 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 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 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 Quantifying the effects of repeated dyeing: morphological, mechanical, and chemical changes in human hair fibers
Repeated hair dyeing significantly damages hair.
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 Nanomechanical characterization of human hair using nanoindentation and SEM
Human hair's strength and flexibility vary by ethnicity, damage, and treatment.
research Cosmeceuticals for Hair and Nails
Hair care products mainly work on the hair's surface and need professional guidance for use.
