660-690 / 1000+ resultsresearch Human scalp hair: geometry, biochemistry, growth parameters and mechanical characteristics
A 6-group geometric classification of human scalp hair is more reliable and objective for testing than an 8-group system.
research Setting reference values in trichology
Normal hair density and diameter ratios were established to help diagnose adult hair loss.
research A modular modeling approach for investigating wool critical buckling from biologically variable along-fiber microstructure
The model helps understand how wool fiber structure affects its strength and flexibility.
research Clinical Snippets
Razor bumps are linked to a genetic variant, misoprostol helps erythromelalgia pain, steroid ointments don't affect skin rhythms, and certain antibodies are common in localized scleroderma.
research Exploring Variation in Ovine KRTAP19-5 and Its Effect on Fine Wool Fibre Curvature in Chinese Tan Sheep
The KRTAP19-5 gene affects wool curvature in Chinese Tan sheep, with Variant B reducing curvature.
research Effect of Rubbing Application on the Skin Permeation of Active Ingredients from Lotion and Cream
Rubbing skin increases absorption of water-soluble drugs from lotions and creams, but not oil-soluble drugs.
research 396 A novel investigator global assessment score for the evaluation of keratosis pilaris
The document's conclusion cannot be provided because the content is not accessible.
research Skin aging as a mechanical phenomenon: The main weak links
Skin aging is largely due to differences in stiffness and elasticity between skin layers, leading to wrinkles.
research Biophysical basis of skin cancer margin assessment using Raman spectroscopy
Raman spectroscopy could effectively guide skin cancer surgery by identifying tumor margins.
research Internal structural changes in age‐related curved hair due to cyclical extension: An IR spectroscopy study
Age-related hair curvature increases due to internal structural changes from grooming.
research 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 varying amino acid composition.
research Characterization of hair lipid images by argon sputter etching-scanning electron microscopy
Hair texture changes with age due to varying levels of lipids.
research Faculty Opinions recommendation of Symmetry breaking of tissue mechanics in wound induced hair follicle regeneration of laboratory and spiny mice.
research Exploring the effects of wetting and free fatty acid deposition on an atomistic hair fiber surface model incorporating Keratin Associated Protein 5-1
Water and fatty acids affect hair's surface differently based on hair damage, and models can help understand hair-cosmetic interactions.
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 Changes in structure and geometric properties of human hair by aging
Older people's hair becomes less shiny because it gets more uneven and curved.
research Comparison of Quantitative Evaluation and Conventional Scar Scale Analysis for Pediatric Pathological Scars
Antera 3D® offers more precise and detailed scar assessment than traditional methods.
research Taxonomy for the assessment of the subjective experience of curly hair manageability
Hair curvature is the main factor affecting curly hair manageability and product preferences.
research Development and Validation of a Dermoscopic Severity Score for Female Pattern Hair Loss
A reliable severity score for female pattern hair loss was developed and validated.
research Mechanical forces in skin disorders
Skin problems can be caused or worsened by physical forces and pressure on the skin.
research Flexabrasion Applied to the Evaluation of the Photodegradation of Hair Fibers
research The Knudsen Nomenclature
Dr. Russell Knudsen's system classifies hair grafts by class, shape, and size for clearer communication in hair restoration surgery.
research The Association Between Scalp Laxity, Elasticity, and Glidability and Donor Strip Scar Width in Hair Transplantation—A New Elasticity Measuring Method
Scalp laxity, elasticity, and glidability are important in hair transplants and can predict scar width at the donor site.
research Assessing Dihydrotestosterone-Induced Skin Alterations in C57BL/6 Mice: Implications for Androgenetic Alopecia through High-Resolution Ultrasound Imaging
DHT causes thicker and less elastic skin, linked to hair loss.
research 1618 Simulated solar radiation (SSR) induced skin inflammation across skin types measured by dynamic optical coherence tomography and laser doppler
Sunlight simulation causes skin inflammation, with different skin types reacting at different levels of exposure.
research A New Universal Follicular Unit Excision Classification System for Hair Transplantation Difficulty and Patient Outcome
The new SFS Scale predicts hair transplant difficulty using hair and skin types, with thick skin and coily hair being hardest to work with.
research Stiffness of Human Hair Correlates with the Fractions of Cortical Cell Types
Hair stiffness is higher when it has more para-like cortical cells.
research Fractography of human hair
Moisture content significantly affects how human hair breaks.
research Expression patterns of EGF and KGF in the skin of Gansu alpine Merino sheep with different fineness of wool
EGF and KGF affect wool fineness in Gansu alpine Merino sheep.
