research Plica polonica: Trichoscopic findings with a brief literature review
Plica polonica is a rare condition where hair becomes irreversibly tangled, and the treatment is to cut the matted hair.
research In vivo formation steps of the hard α-keratin intermediate filament along a hair follicle: Evidence for structural polymorphism
Hair follicles form hard α-keratin filaments in four steps, showing structural differences.
research An ultrastructural study on corkscrew hairs and cigarette‐ash‐shaped hairs observed by dermoscopy of tinea capitis
Corkscrew and cigarette-ash-shaped hairs in tinea capitis are caused by internal hair degradation and external resistance.
research Chapter 4 Cytomechanics of Hair
Hair's strength and flexibility come from its protein structure and molecular interactions.
research Cornified Epithelial Teeth of Jawless Vertebrates Contain Proteins Similar to Keratin-Associated Proteins of Mammalian Skin Appendages
Jawless vertebrates have teeth proteins similar to those in mammalian hair and nails.
research The Formation of Vellus Hair Follicles from Human Adult Epidermis1
Adult human skin can grow new fine hair follicles after a deep exfoliation treatment.
research Azimuthal Scattering from Elliptical Hair Fibers
Light scatters differently from elliptical hair fibers than from circular ones, and a new model better predicts this behavior, especially for shiny highlights.
research Morphological and Morphometric Analysis of Animal Hair From 18th Century Burial Sites in Mazamet (Southwest France)
Animal hair from 18th-century Mazamet burial sites shows locals used goat, badger, cow, or horse fur for clothing, indicating modest economic status.
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 Attraction of sensory fibers by Merkel cells during co-culture of sensory ganglia and hair follcies in collagen-gel
research Outer root sheath keratinization in anagen and catagen of the mammalian hair follicle. A seventh distinct type of keratinization in the hair follicle: trichilemmal keratinization.
Trichilemmal keratinization is a unique process in hair follicles where the outer root sheath turns into keratin without a specific layer.
research Skin Appendage Proteins of Tetrapods: Building Blocks of Claws, Feathers, Hair and Other Cornified Epithelial Structures
Understanding proteins in skin structures like claws and hair is crucial for future research.
research α1-AR agonist induced piloerection protects against the development of traction alopecia
Using a certain drug on the skin can help prevent hair loss caused by pulling on the hair.
research Sparse Hair on the Scalp
A 5-year-old girl has sparse, dry, and brittle hair but is otherwise healthy.
research Human hair morphology: a scanning electron microscopy study on a male Caucasoid and a computerized classification of regional differences.
Hair varies in size and features depending on body region.
research Hair Shaft Abnormalities. Pili Bifurcati: A Scanning Electron Microscopy Analysis
The study found that pili bifurcati causes hair to intermittently split into two branches, each with its own outer layer.
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 Trichohyalin: A structural protein of hair, tongue, nail, and epidermis
research Relationship between the bacterial community structures on human hair and scalp
The scalp has more diverse bacteria, while hair has more bacteria and unique types.
research Synthetic Hair Fiber Implantation: Fishing Lines on the Head
research Scanning Electron Microscopic Study on Collagen Fibrils in the Mink Dermis during the Hair Cycle and Growth
Collagen fibrils in mink skin change structure during hair growth, becoming looser and thicker in the active phase.
research Expression of Basement Membrane Proteins and Interstitial Collagens in Dermal Papillae of Human Hair Follicles
research Study shows thicker hair isn’t necessarily stronger
Thicker hair isn't always stronger.
research Hair Physiology and Grooming
Different hair care methods affect hair health and appearance, and there are many ways to camouflage hair loss.
research Staining of human skin with RGB trichrome unveils a proteoglycan-enriched zone in the hair dermal sheath
A new staining method shows a special area in the hair's skin layer with lots of proteoglycans.
research Casts and pseudocasts
It's important to tell the difference between hair casts, pseudocasts, and nits.
research Hair Keratin: Composition, Structure and Biogenesis
research A Raman spectroscopy investigation of the resilience of hair cuticular scales under uniaxial stress
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.
