60-90 / 1000+ resultsresearch The effect of treatments on the shear modulus of human hair measured by the single fiber torsion pendulum.
Different treatments change the strength and flexibility of human hair.
research An overview of chemical straightening of human hair: technical aspects, potential risks to hair fibre and health and legal issues
Chemical hair straightening can damage hair and health, needing safer alternatives and stricter regulations.
research The G60S Connexin43 Mutant Regulates Hair Growth and Hair Fiber Morphology in a Mouse Model of Human Oculodentodigital Dysplasia
The G60S Connexin43 mutation causes hair growth issues and poor hair quality in mice, similar to human ODDD patients.
research The optical properties of human hair II. The luster of hair fibers
research Distribution and Localization of Hydrophobic and Ionic Chemical Groups at the Surface of Bleached Human Hair Fibers
Bleaching hair removes its protective top layer and exposes more hydrophilic groups, changing its chemical surface and affecting how it interacts with products.
research A discrete transition zone between cuticle and cortex layers of a human hair fibre: changes observed in the presence of breast cancer
Breast cancer alters specific molecular structures in hair, which revert after cancer removal.
research Mechanical Properties of Epoxy-Based Composite Reinforced with Kenaf, Grewia Serrulatta, Human Hair Fibers
research Multiscale modelling of human hair
Human hair becomes weaker and stretches more easily at higher temperatures.
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 Fractography of human hair
Moisture content significantly affects how human hair breaks.
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 Changes of Curvature with Regain of Set Wool and Hair Fibers
Merino wool fibers change shape with moisture, while human hair shape stays the same.
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 Evaluation of a new X-ray fluorescent analysis technique for the creation of a Nordic hair database: elemental distributions within the root and the virgin segment of hair fibers.
The new X-ray technique allows for precise and non-destructive measurement of elements in hair, creating the first database of its kind for a specific ethnic group.
research Natural swing frequency of human hair - a novel method to quantify natural hair collective movements
Human hair movement is affected by its inner structure and chemical treatments.
research Experimental study on the compatibility and degradation of human hair keratin bridging for peripheral nerve defects
Human hair keratin can help nerve regeneration and is a promising material for nerve repair.
research Experimental study on the compatibility and degradation of human hair keratin bridging for peripheral nerve defects
Human hair keratin is a promising material for nerve repair.
research Nanomechanical characterization of human hair using nanoindentation and SEM
Human hair's strength and flexibility vary by ethnicity, damage, and treatment.
research In situ tensile deformation characterization of human hair with atomic force microscopy
AFM helped show how hair changes under tension and the effects of damage and conditioner.
research Human Hair and the Impact of Cosmetic Procedures: A Review on Cleansing and Shape-Modulating Cosmetics
Future hair cosmetics will be safer and more effective.
research Culture of the human pilosebaceous unit, hair follicle and sebaceous gland
The article concludes that developing in vitro models for human hair structures is important for research and reducing animal testing, but there are challenges like obtaining suitable samples and the models' limitations.
research Variation in human hair ultrastructure among three biogeographic populations
Different populations have distinct hair structures related to their ancestry.
research Hair today, gone tomorrow: the degradation and conservation of archaeological hair fibers
Acidic sandy clay damages archaeological hair the most, while dry conditions preserve but make it brittle; silicone oil can help keep the hair flexible.
research Differentiation of nestin-negative human hair follicle outer root sheath cells into neurons in vitro
Human hair follicle cells can be turned into neural stem cell-like cells, which might help treat brain diseases.
research Human hair keratin templates for biomedical applications
Human hair keratin is a promising and sustainable biomaterial for tissue regeneration.
research Stem cell factor combined with matrix proteins promotes attachment and migration of amelanotic melanocyte from human follicle hair
Stem cell factor and certain proteins help melanocytes from hair follicles move and attach better, aiding vitiligo repigmentation.
research Skin equivalent containing collagen-human hair keratin matrice for formation of neodermis
HHK can help restore skin structure.
research Human hair follicle-derived mesenchymal stem cells promote tendon repair in a rabbit Achilles tendinopathy model
