180-210 / 1000+ results research Hair cross-sectioning in uncombable hair syndrome: An easy tool for complex diagnosis
The document suggests finding a simpler, cheaper way to diagnose Uncombable Hair Syndrome.
research Water distribution in human hair microstructure elucidated by spin contrast variation small-angle neutron scattering
The technique showed that human hair has two main parts, with 68% being rigid and the rest flexible, and water swelling affects its structure.
research Mechanical forces in skin disorders
Skin problems can be caused or worsened by physical forces and pressure on the skin.
research An ex vivo comparative study of the tensile strengthening efficacy of protein-derived actives on heavily bleached hair
Protein-derived ingredients can help strengthen bleached hair.
research The toughening transition in hair keratin
The observed "toughening" in keratin was actually due to water evaporation, not a real change in keratin.
research Improved two‐dimensional electrophoretic mapping of Japanese human hair proteins; application to curved and straight Japanese human hairs; and protein identification by MALDI MS and MS/MS quadrupole time‐of‐flight mass spectrometry
The study found that minor protein differences between curved and straight Japanese hair are unlikely to significantly affect hair structure.
research Trichoscopy‐assisted hair pull test: A helpful adjunct to trichoscopy for diagnosing and managing alopecias
The trichoscopy-assisted hair pull test is useful for diagnosing different types of hair loss.
research Measurements of tension on wound edges after strip harvest surgery
Wound tension after hair transplant surgery increases with strip size and is higher on the sides, affecting scarring.
research J. Cosmet. Sci., 59, 263–289 (July/August 2008) Characterization of curved hair of Japanese women with reference to internal structures and amino acid composition
Japanese women's curved hair has an uneven internal structure and varied amino acid composition.
research Proteomic Analysis of Crimped and Straight Wool in Chinese Tan Sheep
Crimped wool has proteins linked to crimp formation, while straight wool has proteins linked to fiber fineness, which can improve wool quality and value.
research Symmetry breaking of tissue mechanics in wound induced hair follicle regeneration of laboratory and spiny mice
Tissue stiffness affects hair follicle regeneration, and Twist1 is a key regulator.
research The Cross-section Trichometer: A New Device for Measuring Hair Quantity, Hair Loss, and Hair Growth
The Cross-section Trichometer is a new tool that can measure hair quantity and detect hair loss and growth.
research A highly sensitive MEMS silicon‐hair device reproducing the function of hair follicle
The device mimics human hair follicles and detects tiny forces and moments with high sensitivity.
research WISP-1 induced by mechanical stress contributes to the fibrosis and hypertrophy of ligamentum flavum via the Hedgehog-Gli1 signaling
Mechanical stress causes ligament thickening through WISP-1 and Hedgehog signaling.
research Hair Shaft Abnormalities. Pili Bifurcati: A Scanning Electron Microscopy Analysis
The study found that pili bifurcati causes hair to intermittently split into two branches, each with its own outer layer.
research Investigating the origins of nanostructural variations in differential ethnic hair types using X‐ray scattering techniques
Different ethnic hair types have unique nanoscopic and molecular features despite having the same basic keratin structure.
research [Analysis of normal human hair keratins by two-dimensional polyacrylamide gel electrophoresis].
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 Monilethrix: an ultrastructural study
Monilethrix hair issues are due to problems in the hair's internodes.
research Structural analysis of human hair single fibres by scanning microbeam SAXS
Hair curliness is due to uneven distribution of different cortices within the hair fiber.
research Tactile and hair-hair friction behavior of hair fibers
Hair feels different when touched and rubs together in various ways.
research Electronic Circular Dichroism Imaging (ECD i ) Casts a New Light on the Origin of Solid‐State Chiroptical Properties
The research found that the properties of solid-state Electronic Circular Dichroism (ss-ECD) are influenced by the orientation of local crystals, which could help in examining and mapping chiral materials like pharmaceutical ingredients.
research Investigation of human hair fibers using lateral force microscopy
Hair treatments like bleaching increase friction by exposing tiny pores on the hair surface.
research Pili trianguli et canaliculi as a phenotypic subtype in patients with central centrifugal cicatricial alopecia: A scanning electron microscopy study
Hair shaft changes may be linked to CCCA, but their role is unclear.
research Keratin network modifications lead to the mechanical stiffening of the hair follicle fiber
Changes in keratin make hair follicles stiffer.
