research Wetting behavior of human hair fibers
Human hair's ability to get wet is complex and can change with treatments, damage, and environment.
research Chronological ageing of human hair keratin fibres
Hair ages as the cuticle wears down, especially beyond 1 meter from the root, affecting its strength and shine.
research Sequence and Expression of Murine Type I Hair Keratins mHa2 and mHa3
mHa2 and mHa3 keratins have different structures and roles in mouse hair and tongue tissues.
research Fractography of human hair
Moisture content significantly affects how human hair breaks.
research Evidence for various calcium sites in human hair shaft revealed by sub-micrometer X-ray fluorescence
The research found two types of calcium in human hair, one that varies among individuals and another that is consistent across people.
research The physical and chemical disruption of human hair after bleaching – studies by transmission electron microscopy and redox proteomics
Bleaching hair causes severe structural and chemical damage, including protein loss and oxidation.
research Photochemical alterations in human hair. I. Artificial irradiation and investigations of hair proteins
Melanin in black hair protects it from sun damage better than light-brown hair.
research Cuticle damage and the tensile properties of human hair
Cuticle damage doesn't affect hair's tensile strength; the cortex is responsible for it.
research Characterization of a gene encoding a cysteine-rich keratin associated protein synthesized late in rabbit hair follicle differentiation
A rabbit gene important for hair development was identified and detailed.
research Study of normal hair and of some malformations with a scanning electron microscope
Hair malformations may occur due to timing issues in hair development.
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 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 Photoageing of Hair Fiber and Photoprotection
Sunlight damages hair, causing cuticle loss, protein changes, and discoloration.
research Perspectives on Hair Evolution Based on Some Comparative Studies on Vertebrate Cornification
Hair in mammals likely evolved from glandular structures, not scales.
research Discrete Nanoscale Distribution of Hair Lipids Fails to Provide Humidity Resistance
Hair lipids do not protect against humidity.
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 The Study on Biological Function of Keratin 26, a Novel Member of Liaoning Cashmere Goat Keratin Gene Family
Keratin 26 affects cashmere goat hair growth and is influenced by various treatments.
research Lipid loses 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 Investigations on the penetration of hydrolyzed wheat proteins into human hair by confocal laser-scanning fluorescence microscopy
Hydrolyzed wheat proteins penetrate all hair types effectively.
research Qualitative investigation of fresh human scalp hair with full-field optical coherence tomography
Melanin density affects hair color, and this method can help in cosmetic assessments and diagnosing hair diseases.
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.
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 Ultrastructural localization of hair keratins, high sulfur keratin-associated proteins and sulfhydryl oxidase in the human hair
