30 / 1000+ resultsresearch Three-dimensional architecture of macrofibrils in the human scalp hair cortex
Human hair has a complex, variable structure with a consistent matrix and double-twist pattern.
research ELECTRON MICROSCOPE STUDIES OF HAIR AND WOOL
Hair and wool have complex microscopic structures with microfibrils and varying cystine content.
research Organization of microfibrils in keratin fibers studied by X-ray scattering
The study improved understanding of keratin fiber structure by showing consistent microfibril diameter but varying distances and electron density profiles.
research Nucleation and growth of macrofibrils in trichocyte (hard-α) keratins
Sheet formation is key to macrofibril structure differences in wool.
research Ultrastructural Localization of Hair Keratins in Human Scalp Hair Shafts as Revealed by Rapid-Freezing Immunocytochemistry.
Hair keratins are mainly on macrofibrils in the cortex and in the endocuticle in the cuticle.
research Analysis of structural changes in permanent waved human hair using Raman spectroscopy
Permanent waving weakens hair by altering its protein structure.
research Direct Observation of Hair Components Involved in Formation of Permanent Waves
Microfibrils are key for permanent waves, and hydrolyzed keratin improves wave formation and hair condition.
research Mechanical Behaviour of Scalp Hair in Premature and Full-Term Neonates
Premature infants have less elastic hair than full-term infants.
research Scarring Folliculitis in the Ectrodactyly-Ectodermal Dysplasia-Clefting Syndrome
The patient with EEC syndrome had scarring alopecia due to deep folliculitis, possibly linked to abnormal hair structure.
research The swelling behaviour of hair studied through the structural change of keratin protein during the permanent waving treatment
Hair structure changes immediately during perm treatment, with initial damage partially restored later.
research Structural change of keratin protein in human hair by permanent waving treatment
Permanent waving damages hair by disrupting its keratin structure.
research Acoustic Fabrication of Collagen–Fibronectin Composite Gels Accelerates Microtissue Formation
Ultrasound helps create gels that speed up tissue formation.
research Discussion: Themes in the Molecular Structure of Hair
Keratin proteins are crucial for hair structure and strength.
research The Cytology and Cytochemistry of the Wool Follicle
Wool follicles are complex, involving interactions between different cell types and structures.
research Reimagining Hair Science: A New Approach to Classify Curly Hair Phenotypes via New Quantitative Geometrical & Structural Mechanical Parameters
New methods to classify curly hair types were developed based on shape and strength.
research Reimagining Hair Science: A New Approach to Classify Curly Hair Phenotypes via New Quantitative Geometrical & Structural Mechanical Parameters
A new system for classifying curly hair types using precise measurements can improve hair care products and cultural inclusion.
research How different is human hair? A critical appraisal of the reported differences in 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 Keratin network modifications lead to the mechanical stiffening of the hair follicle fiber
Changes in keratin make hair follicles stiffer.
research The utility of elastic Verhoeff-Van Gieson staining in dermatopathology
EVG staining is a valuable, simple, and cost-effective method for diagnosing various skin conditions in dermatopathology.
research Proline-rich protein-like PRPL1 controls elongation of root hairs in Arabidopsis thaliana
A gene in Arabidopsis thaliana, AtPRPL1, affects root hair length but not cell wall composition.
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 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.
research pH Dependence of the Coiled-Coil Structure of Keratin Intermediate Filament in Human Hair by 13C NMR Spectroscopy and the Mechanism of Its Disruption
Keratin structure in hair is stable at pH 5-6 but disrupts between pH 6-7.
research USES OF ONION (Allium cepa L.) & ALOE VERA (Aloe barbadensis Miller) POST HAIR DYE TREATMENT
Onion and Aloe vera can help protect hair from damage caused by hair dyes.
research Risks of Protein Conditioner Application under the Impact of Heat and/or Gamma Irradiation in Albino Rats
Repeated use of protein hair conditioner with heat or gamma irradiation can harm skin and hair health in rats.
research Biocompatibility of KAPs-Depleted Residual Hair
KAP-depleted hair causes less immune response and is more biocompatible for implants.
research Elemental hair analysis: A review of procedures and applications
Hair elemental analysis could be useful for health and exposure assessment but requires more standardization and research.
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 Hair in health and disease: an introduction
Hair health depends on various factors and hair loss can significantly affect a person's well-being; understanding hair biology is key for creating effective hair care treatments.
