390-420 / 1000+ resultsresearch 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 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 Spatial Probing of the Properties of the Human Hair Surface Using Wilhelmy Force Profiles
Human hair surface varies in wettability, showing daily and monthly patterns.
research New aspects of the structure of human hair on the basis of optical microscopic observations of disassembled hair parts.
Human hair's strength comes from a honeycomb-like structure and macrofibrils.
research Hair weathering and hair capacitance mapping: a pilot study
Hair capacitance mapping effectively measures hair surface moisture changes.
research Human hair keratins
research 571 Human Hair Follicles can “Taste”: Stimulation of the Bitter Taste Receptor TAS2R4 Inhibits Hair Growth Ex Vivo by Up-Regulating TGF-β2
Activating a bitter taste receptor in hair follicles can stop hair growth by increasing a specific growth factor.
research INTRODUCING THEORY LINKING GENESIS OF HAIR SHAFT BIPOLARITY WITH ARRECTOR PILI MUSCLE PROXIMAL ATTACHMENT
The document suggests that human hair has electrical charges because of a gap in nerve cell coverage that affects electromagnetic radiation.
research Friction and wear studies of human hair and skin
Human hair and skin friction vary by ethnicity, hair type, and environmental conditions.
research 216 Human hair follicles can “smell”: OR2AT4-mediated hair growth regulation
Human hair follicles have a scent receptor that can influence hair growth.
research Human scalp hair as a thermoregulatory adaptation
Tightly curled scalp hair helps reduce heat from the sun, protecting against overheating.
research Knismesis: the aversive facet of tickle
Light tickling can be unpleasant and may feel worse for individuals with autism.
research Interactions between Crossed Hair Fibers at the Nanoscale
Hair fibers interact through classical forces, which are influenced by treatments and products, important for hair care and other applications.
research Elastoinertial effects govern dynamic response of soft hair beds
Hair beds in fluid show nonlinear response due to viscosity, inertia, and elasticity.
research 1407 Mechanical force activation of TGF-β signaling controls hair follicle regression
Muscle around hair follicles controls hair loss by releasing a signal that causes cell death.
research Nanomechanical characterization of human hair using nanoindentation and SEM
Human hair's strength and flexibility vary by ethnicity, damage, and treatment.
research Cell Types Promoting Goosebumps Form a Niche to Regulate Hair Follicle Stem Cells
Muscles and nerves that cause goosebumps also help control hair growth.
research Hair—the most sophisticated biological composite material
Hair is a complex protein fiber with unique properties useful for developing hair products.
research Formation and Structure: An Introduction to Hair
Hair is important for social and sexual communication in humans.
research Hair curvature: a natural dialectic and review
The document concludes that hair curvature can be explained by the growth patterns caused by the shape and separation of cells in the hair follicle and is affected by specific molecular pathways.
research Biomechanics of hair fibre growth: A multi-scale modeling approach
The model shows that factors like follicle shape and stiffness are key for hair growth and anchoring.
research Nanotribological characterization of human hair and skin using atomic force microscopy
The research improved understanding of hair and skin properties across different ethnicities and conditions.
research 1334 Beyond goosebumps: Interactions between the hair follicle, the arrector pili muscle, and the sympathetic nerve during development and hair follicle regeneration
Arrector pili muscle regulates hair follicle stem cells, DNA methylation needed for hair cycling, and Wnt/B-catenin signaling starts hair growth.
research Epithelial skirt and bulge of human facial vellus hair follicles and and associated Merkel cell-nerve complex
Merkel cells are abundant in facial vellus hair follicles, especially during the anagen phase.
research Induction of follicle formation and hair growth by vibrissa dermal papillae implanted into rat ear wounds: vibrissa-type fibres are specified
Implanted dermal papillae can induce hair growth in rat ear wounds.
research Torsional behavior of human hair
Water makes hair more flexible, especially the outer layer.
research Characteristic microstructure of curved human hair
