Research
870-900 / 1000+ results research Autosomal-Dominant Woolly Hair Resulting from Disruption of Keratin 74 (KRT74), a Potential Determinant of Human Hair Texture
A mutation in the KRT74 gene causes tightly curled hair.
research Quasi-Static Torsional Deformation of Single Hair Fibers: Application of a Modeling Approach and Results from Cosmetic Treatments.
The research found that twisting hair fibers can show changes in stiffness and damage, and help tell apart different hair treatments.
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 Chronological ageing of human hair keratin fibres
Hair ages as the cuticle wears down, especially beyond 1 meter from the root, affecting its strength and shine.
research Analysis of structural changes in permanent waved human hair using Raman spectroscopy
Permanent waving weakens hair by altering its protein structure.
research In-Situ Tensile Testing of Hair Fibers in An Environmental Scanning Electron Microscope (ESEM)
Hair fibers break by cuticle cell slipping, shape changing, cuticle fraying, and surface cracking when stretched under specific conditions.
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 Mechanism research of yak hair stretching slenderization based on the changes of conformation and cell shape
Yak hair stretches mainly due to macromolecules slipping past each other.
research Fractography of human hair
Moisture content significantly affects how human hair breaks.
research Morphological analyses in fragility of pili torti with Björnstad syndrome
Pili torti hair is fragile due to loose keratin filaments and weak disulfide bonds.
research Anti-aging Effect and Regression of Wart by Increasing Normal Cell Telomere: The Efficacy of Far-infrared Oily Cream
The far-infrared oily cream helped reduce a wart and had anti-aging effects by increasing telomere length.
research Intrinsic curvature in wool fibres is determined by the relative length of orthocortical and paracortical cells
Wool fibre curvature is due to longer orthocortical cells compared to paracortical cells.
research Clinical Snippets
Melanoma risk tools need improvement, certain gene mutations cause skin diseases and could be treated by targeting those mutations, skin wrinkling may relate to lung aging due to genetic factors, and oxidative stress affects hair loss but can be reduced in low oxygen.
research Monitoring of Wool Stretching Process Using Polarized Second Harmonic Generation
Stretching wool changes its structure and improves fiber alignment.
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 Hair resistance to mechanical wear
Hair's resistance to wear varies by ethnicity and treatment, with less wear indicating stronger hair.
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 Integration Analysis of Transcriptome and Proteome Reveal the Mechanisms of Goat Wool Bending
The research identified key proteins and genes that may influence wool bending in goats.
research Multiscale modelling of human hair
Human hair becomes weaker and stretches more easily at higher temperatures.
research The Mean Staple Length of Wool Fibre Is Associated with Variation in the Ovine Keratin-Associated Protein 21-2 Gene
The KRTAP21-2 gene affects wool length and quality in sheep.
research Pili annulati with fragility: Electron microscopic findings of a case
The study found that hair fragility in Pili annulati may be caused by cavities and damage within the hair shafts.
research Investigation of aging effects in human hair using atomic force microscopy
Aging makes hair thinner and rougher, with less clear edges.
research Effects of permanent waving on changes of protein and physicomorphological properties in human head hair.
Repeated digital perming with sodium thioglycolate lotion significantly damages hair protein and structure.
research Scalp lesions, in images
Different scalp conditions can lead to hair loss or tumors, with treatments varying from creams to surgery; early detection is crucial.
research Effect of oil application, age, diet, and pigmentation on the tensile strength and breaking point of hair
Children's hair is more elastic, but tensile strength is similar across different factors.
research Intermolecular disulfide cross-linked structural change induced by permanent wave treatment of human hair with thioglycolic acid.
Permanent wave treatment with thioglycolic acid changes hair structure by altering disulfide bonds.
research Update on detection, morphology and fragility in pili annulati in three kindreds
Careful light microscopy is crucial for detecting mild cases of pili annulati, which weakens hair and varies widely in expression.
research Whiskers amiss, a new vibrissae and hair mutation near the Krt1 cluster on mouse Chromosome 11
A new mutation in mice causes crooked whiskers and messy hair.
