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 The in vitro Assembly of Hair Follicle Keratins: Comparison of Cortex and Companion Layer Keratins
Different conditions affect how hair proteins assemble, and certain mutations can change their structure.
research Trichilemmoma.Cell biology of the normal human outer root sheath.
The outer root sheath in hair follicles changes during growth, with different keratinization processes in its layers.
research 13-cis-Retinoic Acid Affects Sheath-Shaft Interactions of Equine Hair Follicles in Vitro
research X-rays studies of the structure of hair, wool, and related fibres. II. - The molecular structure and elastic properties of hair keratin
Stretched hair has a similar structure to natural silk, showing hair's elasticity involves reversible changes within its molecules.
research Bubble hair
Bubble hair deformity may be caused by hair shaft trauma and can improve with gentle hair care.
research A single-cell transcriptomic atlas elucidates the hair cycle and apoptosis mechanisms in goat hair follicles
The study maps goat hair follicle cells, revealing key genes and pathways involved in hair growth and cell death.
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 Human stratified squamous epithelia differ in cellular fatty acid composition
Fatty acid composition in human skin, mouth, and hair cells varies with keratinization, and cultured cells show essential fatty acid deficiency.
research The walking dead: sequential nuclear and organelle destruction during hair development
Hair cells lose their nucleus and mitochondria in a specific order as they fill with keratin, which could help develop treatments for hair issues.
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 Expression pattern of human hair keratin basic 1 (hHbl) in hair follicle and pilomatricoma
hHbl gene is active in hair shaft cells and some pilomatricomas.
research Pili Annulati with Multiple Fragile Hairs
Frequent hairdryer use may worsen hair fragility in people with Pili Annulati.
research Internal structural changes in age‐related curved hair due to cyclical extension: An IR spectroscopy study
Age-related hair curvature increases due to internal structural changes from grooming.
research Horse hair follicles: A novel dermal stem cell source for equine regenerative medicine
Horse hair follicles could be a new source of stem cells for healing horses.
research Histological and dermatoscopic description of sphynx cat skin
Sphynx cats have abnormal hair follicles and keratinization affecting their skin.
research The structure of human trichohyalin : potential multiple roles as a functional ef-hand-like calcium-binding protein, a cornified cell envelope precursor, and an intermediate filament-associated (cross-linking) protein
Trichohyalin is a versatile protein involved in hair and skin structure.
research Double-wavelength laser scanning microphotometer (DWLSM) for in-vitro hair shaft and surrounding tissue imaging
The DWLSM provides detailed imaging of hair shafts and follicles with high accuracy.
research Monilethrix
Monilethrix has no effective treatment, but avoiding hair trauma helps manage it.
research Eruptive vellus hair cysts: An underdiagnosed entity
Eruptive vellus hair cysts are often missed in diagnoses.
research Comparative study of male and female human hair: A microscopic analysis.
Male and female human hairs have different microscopic structures that can help in forensic analysis.
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.
research Age-related changes in the hair follicle and hair shaft in women in the parietal region
As women age, hair follicles decrease in number and hair width tends to reduce.
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 Abnormal inner root sheath of the hair follicle in the loose anagen hair syndrome: An ultrastructural study
Loose anagen hair syndrome is caused by structural abnormalities in the hair follicle's inner root sheath.
research Human epithelial hair follicle stem cells and their progeny: Current state of knowledge, the widening gap in translational research and future challenges
We need more research to better understand human hair follicle stem cells for improved treatments for hair loss and skin cancer.
research Ultrastructural localization of hair keratins, high sulfur keratin-associated proteins and sulfhydryl oxidase in the human hair
Hair proteins change location and structure as hair cells mature.
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.
