research Structural Analysis of Human Hair Fibers Under the Ultra-High Voltage Electron Microscope
Human hair structure varies by ethnicity, and certain treatments can improve hair condition and appearance.
research Lipid Losses and Barrier Function Modifications of the Brown-to-White Hair Transition
White hair has less lipid content and absorbs water differently than brown hair.
research The Secrets of Beautiful Hair: Why Is It Flexible and Elastic?
Beautiful hair is flexible and elastic due to its unique double-layered structure and can be enhanced with succinic acid treatment.
research Nanomechanical Characterization of Human Hair Using Nanoindentation and SEM
Human hair's strength and flexibility vary by ethnicity, damage, and treatment.
research Exogenous and Endogenous Lipids of Human Hair
Removing external lipids from hair reduces moisture and increases strength, while removing internal lipids decreases water permeability.
research Effect of Ethnicity and Treatments on In Situ Tensile Response and Morphological Changes of Human Hair Characterized by Atomic Force Microscopy
Different ethnicities and treatments affect human hair strength and structure.
research Assessment of Hair Density and Caliber in Caucasian and Asian Female Subjects with Female Pattern Hair Loss Using the Folliscope
Caucasian hair is denser, but Asian hair is thicker in female pattern hair loss patients.
research Azimuthal Scattering from Elliptical Hair Fibers
Light scatters differently from elliptical hair fibers than from circular ones, and a new model better predicts this behavior, especially for shiny highlights.
research Stability of Opiates in Hair Fibers After Exposure to Cosmetic Treatment
Cosmetic treatments like bleaching and perming can greatly reduce opiate levels in hair, possibly leading to false-negative drug tests.
research Interactions Between Crossed Hair Fibers at the Nanoscale
Hair fibers interact through classical forces, which are influenced by treatments and products, important for hair care and other applications.
research Charge Density Alterations in Human Hair Fibers: An Investigation Using Electrostatic Force Microscopy
The study found that a polymer treatment changes the charge on hair surfaces, making bleached hair smoother and less porous.
research Morphological Analysis of Polymers on Hair Fibers by SEM and AFM
Polyquaternium 7® builds up on hair, improving its look and feel, and AFM is good for measuring these changes.
research Raman Spectroscopy and Electronic Microscopy Structural Studies of Caucasian and Afro Human Hair
Hair treatments cause significant structural changes, especially with excessive heat, regardless of ethnicity.
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 Characterization of the Mechanical Properties of the Cortex Region of Human Hair Fibers by Multiparametric Atomic Force Microscopy Mapping
Atomic Force Microscopy is a more accurate way to assess hair damage and the effect of cosmetic treatments.
research The Physical Properties of Hair Fibers
I'm sorry, but I can't provide a summary without the content of the document.
research Heat-Damaged Evaluation of Virgin Hair
Heat damages hair, with Asian hair losing more protein than Caucasian hair.
research Physical Characterization of the Hair of Mexican Women
Mexican women's hair is between Asian and Caucasian hair in thickness and shape, with varied strength and some damage.
research How Different Is Human Hair? A Critical Appraisal of Global Hair Fibre Characteristics and Properties Towards Defining a More Relevant Framework for Hair Type Classification
Human hair varies widely and should be classified by curl type rather than race.
research Advances in the Chemical Structure of the Hair Surface, Surface Forces and Interactions
Understanding hair surface properties is key for effective hair care products.
research External Lipid Function in Ethnic Hairs
African hair has the most lipids, while Caucasian hair is more hydrated and stronger.
research Reactive Keratin Derivatives: A Promising Strategy for Covalent Binding to Hair
Modified keratin binds better to hair, especially bleached hair.
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.
