300-330 / 1000+ results research Evolution of Trichocyte Keratins
Hair keratins evolved from ancient proteins, diversifying through gene changes, crucial for forming claws and later hair in mammals.
research Curly Hair Follicle is Sculpted by a Contracted Arrector Pili Muscle. A Hypothesis with Treatment Implications
Relaxing certain muscles might straighten curly hair.
research Silk secretion from tarantula feet revisited: alleged spigots are probably chemoreceptors
Tarantula feet likely have chemoreceptors, not silk-producing parts.
research Mechanical anisotropy of hair affected by genetic diseases highlights structural information related to differential crosslinking in keratins
research Molecular modeling and structural characterization of a high glycine–tyrosine hair keratin associated protein
The 3D structure of a key hair protein was modeled, revealing specific helical structures and stabilization features.
research Pili Annulati
The patient's hair has unique structural differences with alternating bright and dark bands.
research The Ratio of Typical Clubbing in Pulled-Out Hairs as a Useful Marker in Predicting the Course of Alopecia Areata
Examining hair shape can help predict Alopecia Areata's progression.
research Rethinking the mechanics of hair growth: evidence for a pulling model
research Complex Hair Cycle Domain Patterns and Regenerative Hair Waves in Living Rodents
Mice hair growth patterns get more complex with age and can change with events like pregnancy or injury.
research The secret life of the hair follicle
Hair follicles create different cell layers and proteins, controlled by various molecules.
research Collagen-type synthesis in human-hair papilla cells in culture
research Determination of the cuticula thickness of human and porcine hairs and their potential influence on the penetration of nanoparticles into the hair follicles
Nanoparticles penetrate hair follicles better when their size matches the cuticula thickness.
research Cinnamic acid promotes elongation of hair peg-like sprouting in hair follicle organoids via oxytocin receptor activation
Cinnamic acid may help hair grow by activating oxytocin receptors.
research A Novel Epithelial Keratin, hK6irs1, is Expressed Differentially in All Layers of the Inner Root Sheath, Including Specialized Huxley Cells (Flügelzellen) of the Human Hair Follicle
A new keratin, hK6irs1, is found in all layers of the hair follicle's inner root sheath.
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 Three-dimensional microanatomy of longitudinal lanceolate endings in rat vibrissae
Rat vibrissae have sensory terminals with specific structures that help detect hair movements.
research Known and Unknown Features of Hair Cuticle Structure: A Brief Review
The hair cuticle is made of tough proteins that protect the hair, but more research is needed to fully understand its structure.
research Hard X-ray Microscopic Images of the Human Hair
High-resolution x-ray images showed three main structures in human hair: medulla, cortex, and cuticle.
research A highly resistant structure between the cuticle and the cortex of human hair. II . CARB , a penetration barrier
CARB is a strong barrier in human hair that prevents dye penetration.
research A Study of Aggregation Structures and Tensile Properties of Hair Fibers
research A Keratin Fiber Sheath
Hair fibers may have a unique, non-protein sheath not previously identified.
research Acquired progressive kinking of hair affecting the scalp and eyelashes in an adult woman
A woman developed rare, unexplained curly hair on her scalp and eyelashes.
research Morphology and Properties of Hair
Hair is made of strong keratin fibers that protect against the environment.
research In Vitro Assembly and Structure of Trichocyte Keratin Intermediate Filaments
Scientists successfully created mouse hair proteins in the lab, which are stable and similar to natural hair.
research Pili Torti: A Feature of Numerous Congenital and Acquired Conditions
Pili torti is a rare condition where hair is twisted and breaks easily, often linked to genetic disorders or other health issues.
research Isolation and characterization of genomic clones of human sequences presumably coding for hair cysteine-rich proteins
A new protein linked to hair strength was identified, aiding in understanding brittle hair conditions.
research The Arrector Pili Muscle and the Follicular Unit of the Scalp: A Microscopic Anatomy Study
The study found that hair follicles are above muscle connections in the scalp, which may help protect stem cell areas.
research Bubble hair – a possible explanation for its distribution
Using a blow dryer in a certain way can cause localized hair damage with bubble formation inside the hair.
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.
