The document explains common hair disorders and the basics of hair anatomy and life cycle.
research Ultrastructural characteristics of trichilemmal cysts: report of two cases
Trichilemmal cysts may form from hair follicle outer root sheath growth.
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 Three-dimensional architecture of macrofibrils in the human scalp hair cortex
Human hair has a complex, variable structure with a consistent matrix and double-twist pattern.
research Pili Trianguli et Canaliculi Is a Defect of Inner Root Sheath Keratinization
The hair defect is due to abnormal inner root sheath keratinization.
research A case of pili torti in a young adult domestic short-haired cat
A young cat had a rare hair condition with twisted hair shafts but stayed healthy.
research Unilateral Straight Hair—A Symptom of Acquired Horner's Syndrome in a Neonate
A baby girl's hair turned straight on one side due to a neck tumor and surgery, but it returned to curly as she recovered.
research The Ziering Whorl Classification of Scalp Hair
The conclusion is that creating natural-looking hair restoration requires replicating natural scalp whorl patterns and inserting grafts at specific angles.
research 712 Using scanning electron microscopy to elucidate the role of hair shaft malformation in the pathogenesis of Central Centrifugal Cicatricial Alopecia
Hair shaft malformation contributes to Central Centrifugal Cicatricial Alopecia.
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 The Ziering Whorl Classification of Scalp Hair
Craig Ziering created a system to classify scalp hair patterns, important for improving hair restoration surgery results.
research Paired Ear Creases of the Helix (PECH): A Possible Physical Sign
Ear creases might indicate heart disease risk, needing more research.
research Pili trianguli et canaliculi as a phenotypic subtype in patients with central centrifugal cicatricial alopecia: A scanning electron microscopy study
Hair shaft changes may be linked to CCCA, but their role is unclear.
research Investigating the internal structure of sheep wool hair fibre using new microscopic techniques
Curly wool has more orthocortex than straight wool.
research Effect of Needle Geometry on Insertion Force of Different Hair Implanters
Needle shape affects the force needed for hair implants, with certain shapes reducing the effort required.
research When whorls collide: the development of hair patterns in frizzled 6 mutant mice
Hair follicles in mutant mice self-organize into ordered patterns within a week.
research Radially patterned morphogenesis of murine hair follicle placodes ensures robust epithelial budding
research 1412 “Telescope model” for coordinated organ morphogenesis and stem cell formation
Developing hair follicles form from ring-shaped patterns, with future stem cells originating from the outer ring, not the upper layers, as previously thought.
research Circle Hairs in a Patient with Multiple Myeloma
An elderly woman with cancer improved after treatment for a rare skin condition with coiled hairs.
research Vertebral epidermal transamidases
Transamidases are present in the epidermis but their exact role is unclear.
research A case of localized uncombable hair syndrome
A 4-year-old girl had a rare hair disorder affecting only part of her scalp.
research Hair Whorls in the Dog (Canis familiaris). I. Distribution
Most dogs have hair whorls on their chest and limbs, with shelter dogs and short-haired dogs having more chest whorls.
research Structure of the sinus hair follicle in the big‐clawed shrew, Sorex unguiculatus
The big-clawed shrew's sinus hair follicles are highly specialized for sensing vibrations.
research Trichological analysis on hair of German shepherd dog
German shepherd hair varies in color and pattern but is flat with a consistent internal structure.
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 Variation in the ovine trichohyalin gene and its association with wool curvature
Variation in the TCHH gene affects wool curliness in sheep.
research Cyclical dermal micro-niche switching governs the morphological infradian rhythm of mouse zigzag hair
Mouse zigzag hair bends form due to a 3-day cycle of changes in hair progenitors and their environment.
research Fractal geometry and topology abstracted from hair fibers
Hair fibers have fractal patterns with properties related to the golden mean, which may affect their functionality.
