Research
930-960 / 1000+ resultsresearch μ-Crystallin, Thyroid Hormone-binding Protein, is Expressed Abundantly in the Murine Inner Root Sheath Cells
μ-Crystallin may help hair growth by affecting thyroid hormone levels in mouse hair follicles.
research The structure of hair and follicles of mice carrying the naked (N) gene
Mice with the naked gene have missing or abnormal hair cells.
research Analysis of heterogeneous reaction between reducing agents and keratin fibers using Raman spectroscopy and microspectrophotometry
The study found that thioglycolic acid breaks down hair bonds more consistently than l-cysteine, which is less damaging to hair.
research Reactive keratin derivatives: A promising strategy for covalent binding to hair
Modified keratin binds better to hair, especially bleached hair.
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 Chapter 4 Cytomechanics of Hair
Hair's strength and flexibility come from its protein structure and molecular interactions.
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 Prospective ultramorphological characterization of human hair by optical coherence tomography
OCT can identify hair structures, but chemical treatments can damage them.
research Photoageing of Hair Fiber and Photoprotection
Sunlight damages hair, causing cuticle loss, protein changes, and discoloration.
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 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 Chemical and physical treatments damage Caucasian and Afro‐ethnic hair fibre: analytical and image assays
Chemical and physical treatments like bleaching, dyeing, and UV radiation damage both Caucasian and Afro-ethnic hair.
research An ultrastructural study on corkscrew hairs and cigarette‐ash‐shaped hairs observed by dermoscopy of tinea capitis
Corkscrew and cigarette-ash-shaped hairs in tinea capitis are caused by internal hair degradation and external resistance.
research Progenitor‐cell‐enriched micrografts as a novel option for the management of androgenetic alopecia
Micrografts promote hair growth in androgenetic alopecia treatment.
research Three‐dimensional imaging and analysis of the surface of hair fibres using scanning electron microscopy
The new 3D imaging method accurately measures hair surface details quickly.
research Heat‐damaged evaluation of virgin hair
Heat damages hair, with Asian hair losing more protein than Caucasian hair.
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 The structural implications of water hardness metal uptake by human hair
Human hair absorbs calcium and magnesium from tap water, affecting its structure and styling properties.
research Copper and calcium uptake in colored hair
Hair coloring increases copper and calcium uptake, damaging hair and reducing shine.
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 Hair Mechanical Properties Depending On Age And Origin
Hair properties vary with age and ethnic origin.
research Microscopical characterization of known postmortem root bands using light and scanning electron microscopy
The research found that postmortem root bands in hair are likely caused by the breakdown of a specific part of the hair's inner structure after death.
research Understanding breakage in curly hair
Curly hair breaks due to mechanical damage and environmental factors, not chemical makeup, and needs ongoing care to prevent breakage.
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 Copper in Green Hair: A Quantitative Investigation by Electron Probe X-Ray Microanalysis
Green hair has high copper levels due to contaminated water and damaged hair cuticles.
research Structure of intermediate filament assembly in hair deduced from hydration studies using small-angle neutron scattering
Hair's internal fibers are arranged in a pattern that doesn't let much water in, and treatments like oils and heat change how much water hair can absorb.
