360-390 / 1000+ resultsresearch Multiscale modelling of human hair
Human hair becomes weaker and stretches more easily at higher temperatures.
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 Hair—the most sophisticated biological composite material
Hair is a complex protein fiber with unique properties useful for developing hair products.
research Structure of intermediate filament assembly in hair deduced from hydration studies using small-angle neutron scattering
Hair's internal fibers are arranged in a pattern that doesn't let much water in, and treatments like oils and heat change how much water hair can absorb.
research Keratin formation in the hair follicle
Keratin fibrils in hair form and stop growing at specific points in the follicle.
research Unruly hair
The document concludes that unruly hair can be congenital or acquired, often lacks specific treatments, and can be managed with oils and short hairstyles.
research Cryo-Electron Microscopy of Trichocyte (Hard α-Keratin) Intermediate Filaments Reveals a Low-Density Core
Trichocyte filaments have a low-density core and may include proteins for hair structure.
research Disulfide Cross-Linked Network Structure of Intermediate Filament and Matrix in Hair and Wool Cortices
Hair and wool strength is affected by the number and type of bonds in their protein structures, with hair having more protein aggregates than wool.
research Pseudopili Annulati in a Dark‐Haired Individual: A Light and Electron Microscopic Study
A dark-haired Chinese girl had hair that looked banded under certain light but was normal under a microscope.
research Curly Hair Follicle is Sculpted by a Contracted Arrector Pili Muscle. A Hypothesis with Treatment Implications
Curly hair may be caused by a muscle contraction, and muscle relaxants might help treat it.
research Fine Structure of Perifollicular Nerve Endings in Human Hair
research Hair structure anatomy and comparative anatomy1 1Dedicated to the memory of the late Dr. R. E. Rivett whose untimely death prevented his role in co-authorship.
Human hair is complex and grows in cycles starting from embryonic life.
research Acquired curved hair is caused by fusion of multiple hair matrix cells
Curved hair can develop when hair cells merge abnormally during growth.
research Some electron microscope observations on hardening in the human hair follicle
The hair follicle structure is more complex than thought, with new findings on protein formation.
research Woolly Hair in Two Siblings
Two siblings have a rare genetic condition causing curly, coarse hair.
research De novo filament formation by human hair keratins K85 and K35 follows a filament development pattern distinct from cytokeratin filament networks
Human hair keratins K85 and K35 create unique filament patterns important for early hair formation.
research ‘Plica neuropathica’: Matting of Hair
A girl's severely tangled hair couldn't be fixed and had to be cut due to a rare condition called plica neuropathica.
research 2P546 Structural Analysis of Curly and Straight Human Hair Fibers by Scanning Microbeam SAXS(52. Bio-imaging,Poster Session,Abstract,Meeting Program of EABS & BSJ 2006)
Curly and straight hair differ in how their internal fibers are arranged.
research Tight junctions form a barrier in porcine hair follicles
Tight junctions create a barrier in pig hair follicles that controls what can enter the skin.
research Keratin network modifications lead to the mechanical stiffening of the hair follicle fiber
Changes in keratin make hair follicles stiffer.
research The twisting tale of woolly hair: a trait with many causes
New genes linked to woolly hair have been found, which could help treat it and change hair texture.
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 Torsional behavior of human hair
Water makes hair more flexible, especially the outer layer.
research Plica neuropathica: Bird's nest under dermatoscope
Plica neuropathica is a tangled hair condition that may be caused by hair damage or psychiatric issues and is treated by cutting the hair and addressing mental health.
research X-rays studies of the structure of hair, wool, and related fibres. II. - The molecular structure and elastic properties of hair keratin
Stretched hair has a similar structure to natural silk, showing hair's elasticity involves reversible changes within its molecules.
research Quantifying whole human hair scalp fibres of varying curl: A micro‐computed tomographic study
Human hair varies in structure based on curl type, with high curl hair showing the most differences.
research [Frizzy hair pathology].
Frizzy hair is fragile and can lead to hair loss and damage if not properly cared for.
research "Curly" Wood and Tiger Tails
Tiger tail bands in hair are caused by wavy hair fibers with melanin, unlike straight fibers in normal hair.
research INTRODUCING THEORY LINKING GENESIS OF HAIR SHAFT BIPOLARITY WITH ARRECTOR PILI MUSCLE PROXIMAL ATTACHMENT
