210-240 / 1000+ results research Human hair keratin network and curvature
Curly hair shape is due to uneven growth patterns in the hair follicle.
research Fine structure and immunocytochemistry of monotreme hairs, with emphasis on the inner root sheath and trichohyalin‐based cornification during hair evolution
Monotreme hair structure and protein distribution are similar to other mammals, but their inner root sheath cornifies differently, suggesting a unique evolution from reptile skin.
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 Curl secret in cells
Hair curliness is caused by the arrangement and length of two different cell types.
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 morphological changes of mammalian hair scales
Mammalian hair scales change from smooth to wavy due to friction.
research The three-dimensional microvascular and collagen fibrillar arrangements around rat vibrissa hairs as revealed by scanning electron microscopy
The lower part of rat vibrissa hair gets more blood and is well-protected for growth.
research Hoxc13 mutant mice lack external hair
Hoxc13 gene is essential for hair, nail, and papilla development.
research Divergent genetic mechanism leads to spiny hair in rodents
Rodent spiny hair traits are due to genetic factors other than the Edar gene.
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 Pathogenesis in pili torti: morphological study
Pili torti hair twists due to uneven outer root sheath cell development.
research Single-Cell Transcriptomics Reveals the Molecular Anatomy of Sheep Hair Follicle Heterogeneity and Wool Curvature
The research identified genes that explain why some sheep have curly wool and others have straight wool.
research TRICHOSTASIS SPINULOSA
Trichostasis spinulosa mainly affects the nose, with many tiny hairs in one follicle, possibly influenced by hormones and sunlight.
research Circle hairs are not rolled hairs
research Chapter 4 Cytomechanics of Hair
Hair's strength and flexibility come from its protein structure and molecular interactions.
research Catagen in the hairless house mouse
Hairless mice have longer hair follicles and abnormal structures during the catagen phase.
research ELECTRON MICROSCOPE STUDIES OF HAIR AND WOOL
Hair and wool have complex microscopic structures with microfibrils and varying cystine content.
research Hox in the Niche Controls Hairy-geneity
Hox genes control hair growth patterns in mammals by regulating stem cell activity in the skin.
research J. Cosmet. Sci., 59, 263–289 (July/August 2008) Characterization of curved hair of Japanese women with reference to internal structures and amino acid composition
Japanese women's curved hair has an uneven internal structure and varied amino acid composition.
research Comparative aspects of the inner root sheath in adult and developing hairs of mammals in relation to the evolution of hairs
The inner root sheath evolved to help hair grow safely through the skin in mammals.
research Circle hairs involving the extremities in a young girl
Circle hairs are harmless, spiral-shaped body hairs that don't need medical treatment.
research Organization and Expression of Hair Follicle Genes.
Hair growth is controlled by specific gene clusters and proteins, and cysteine affects hair gene expression in sheep.
research Ultrastructural localization of hair keratins, high sulfur keratin-associated proteins and sulfhydryl oxidase in the human hair

Curly wool has more orthocortex than straight wool.
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 Intrinsic curvature in wool fibres is determined by the relative length of orthocortical and paracortical cells
Wool fibre curvature is due to longer orthocortical cells compared to paracortical cells.
