360-390 / 1000+ resultsresearch A highly resistant structure between the cuticle and the cortex of human hair.
research Impact of acid (”progressive brush”) and alkaline straightening on the hair fiber: Differential effects on the cuticle and cortex properties
Glyoxylic acid straighteners cause more protein loss but have similar hair strength effects as traditional alkaline straighteners.
research Activation of the Notch pathway in the hair cortex leads to aberrant differentiation of the adjacent hair-shaft layers
Notch pathway activation causes abnormal hair layer development.
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 Hair Follicles in Hirosaki Hairless Rats with Deletion of Basic Hair Keratin Genes. Enlarged Medulla, Loss of Cuticle and Long Catagen
Hirosaki hairless rats have sparse, twisted hair due to missing hair keratin genes.
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 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 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 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 Analysis of structural change in keratin fibers resulting from chemical treatments using Raman spectroscopy
Chemical hair straightening changes hair proteins and mostly fixes broken bonds.
research Measuring changes in chemistry, composition, and molecular structure within hair fibers by infrared and Raman spectroscopic imaging
Infrared and Raman imaging can non-destructively analyze hair structure and help diagnose hair conditions.
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 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 Distribution Analysis of Triglyceride Having Repair Effect on Damaged Human Hair by TOF-SIMS
Hydrogenated palm oil repairs and conditions damaged hair by preventing swelling.
research Volume Changes During Water Binding to Hair Fibers
Hair increases in size when it absorbs water, and treatments like bleaching affect how much water it can take in.
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 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 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 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 Technique for Processing and Routing Staining of Hair Samples for Histological Study
A new method effectively stains hair samples for study without losing hair sections.
research Cross‐linked features of mouse pelage hair resistant to detergent extraction
Two mouse mutants have defective hair cuticle cross-linking.
research Novel Type I Hair Keratins K39 and K40 Are the Last to be Expressed in Differentiation of the Hair: Completion of the Human Hair Keratin Catalog
K39 and K40 are the last keratins expressed in hair development, completing the hair keratin catalog.
research Analysis of structural changes in permanent waved human hair using Raman spectroscopy
Permanent waving weakens hair by altering its protein structure.
research Trichothiodystrophy: an ultrastructural study of the hair follicle
Trichothiodystrophy causes abnormal protein deposits and distortion in hair follicles.
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 Transglutaminase-3 Enzyme: A Putative Actor in Human Hair Shaft Scaffolding?
TGase 3 helps build hair structure by forming strong bonds between proteins.
research Exploring a biological tissue from atomic to macroscopic scale using synchrotron radiation: example of hair.
Hair has unevenly distributed proteins and lipids, with lipids mainly in the cuticle and proteins in the cortex and medulla.
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 Human pollution exposure correlates with accelerated ultrastructural degradation of hair fibers
Pollution exposure speeds up hair damage.
research Influence of Oxidative and/or Reductive Treatment on Human Hair (I): Analysis of Hair-Damage after Oxidative and/or Reductive Treatment
