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 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 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 Scattering from Elliptical Hair Fibers Based on Microfacet Theory
research Bubble hair
Bubble hair deformity may be caused by hair shaft trauma and can improve with gentle hair care.
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 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 Pili Trianguli et Canaliculi Is a Defect of Inner Root Sheath Keratinization
The hair defect is due to abnormal inner root sheath keratinization.
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 Improved two‐dimensional electrophoretic mapping of Japanese human hair proteins; application to curved and straight Japanese human hairs; and protein identification by MALDI MS and MS/MS quadrupole time‐of‐flight mass spectrometry
The study found that minor protein differences between curved and straight Japanese hair are unlikely to significantly affect hair structure.
research New aspects of the structure of human hair on the basis of optical microscopic observations of disassembled hair parts.

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.
research Investigating the internal structure of sheep wool hair fibre using new microscopic techniques
Curly wool has more orthocortex than straight wool.
research Morphological and Macromolecular Structure
research Morphological and Macromolecular Structure
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 Local structure of human hair spatially resolved by sub-micron X-ray beam
Human hair has a new region with ordered filaments and the cuticle contains β-keratin sheets.
research Different orientation of the incisions: an efficient method to facilitate the implantation process
Changing the direction of cuts can make it easier to put in implants.
research Reimagining Hair Science: A New Approach to Classify Curly Hair Phenotypes via New Quantitative Geometric and Structural Mechanical Parameters
New methods can better classify curly hair types and lead to improved hair care products.
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 Scalp Hair-II: Tubular Structure and Material Flow Property of the Medulla.
The medulla in Asian scalp hair has a tubular structure that allows ions and large molecules to flow through it.
research Variation in the ovine trichohyalin gene and its association with wool curvature
Variation in the TCHH gene affects wool curliness in sheep.
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 Proliferating trichilemmal cyst with histological malignant transformation: Identification of hair sheath keratins in the tumor.
A hair cyst can become cancerous, showing specific keratins from the hair sheath.
