research Supplementary Material for: Life of the B10 mouse: a view from the hair follicles and tissue stem cells
Mouse skin and hair aging starts at 200 days, with changes in hair follicles and more white hairs as signs of aging.
research The RAIG Family Member, GPRC5D, Is Associated with Hard-Keratinized Structures
GPRC5D is linked to the formation of hair, nails, and certain tongue areas.
research Apoptosis in growing hair follicles following gamma-irradiation and application for the evaluation of radioprotective agents.
Radiation increases cell death in hair follicles, but certain treatments can protect against this effect.
research Human hair production by scalp samples grafted onto nude mice. Biochemical data on normal human hair and the genetic defect trichothiodystrophy
Grafted human scalp samples on mice can produce human hair, useful for studying hair genetics.
research Ceramic flat irons: Improper use leading to acquired trichorrhexis nodosa
Improper use of ceramic flat irons can cause severe hair damage.
research Experimental Methods
Human hair's structure and properties were studied using advanced microscopes and mechanical tests.
research Catagen in the hairless house mouse
Hairless mice have longer hair follicles and abnormal structures during the catagen phase.
research A Note on Postinflammatory Hair Darkening
Hair can darken after inflammation and then return to its original color.
research The failure behavior of the anchorage of hairs during slow extraction
Growing hairs are easier to pull out than resting hairs due to different anchorage strengths.
research AN UPDATE OF HAIR SHAFT DISORDERS
Advances in genetics may lead to targeted treatments for hair disorders.
research A Rapid Extraction Procedure of Human Hair Proteins and Identification of Phosphorylated Species.
A new method quickly extracts and identifies proteins from hair and other keratin sources.
research Monilethrix
A boy with monilethrix has brittle hair that breaks easily due to a genetic condition, which might improve by puberty.
research [Three-dimensional culture of plucked human hair follicles inside the collagen gel matrix].
Human hair follicles can grow and form structures in a collagen gel, useful for studying hair cell growth.
research Cryo-Electron Microscopy of Trichocyte (Hard α-Keratin) Intermediate Filaments Reveals a Low-Density Core
Trichocyte filaments have a low-density core and may include proteins for hair structure.
research Structural investigation on damaged hair keratin treated with α,β-unsaturated Michael acceptors used as repairing agents
Treatments improved hair surface and scale structure but didn't increase certain bonds in the hair cortex.
research 1314 Advanced age impairs self-renewal and biases fate choice of hair follicle dermal stem cells
Older hair follicle stem cells have a reduced ability to renew themselves, leading to more hair loss.
research Induction of Hard Keratin Expression in Non-Nail-Matrical Keratinocytes by Nail-Matrical Fibroblasts through Epithelial-Mesenchymal Interactions
Nail-matrical fibroblasts can make non-nail cells produce hard keratin, useful for nail repair.
research The Intermediate Filament Architecture as Determined by X-Ray Diffraction Modeling of Hard α-Keratin
Hard α-keratin in hair has a unique, nonordered structure, different from other fibers.
research The swelling behaviour of hair studied through the structural change of keratin protein during the permanent waving treatment
Hair structure changes immediately during perm treatment, with initial damage partially restored later.
research EXPRESS: Structure Evolution in Hair Fibres During Strain and the Effect of Relative Humidity
Humidity affects hair structure changes during stretching.
research Immunohistochemical analysis of tissue remodelling during the anagen-catagen transition of the human hair follicle
The inner root sheath is crucial for hair follicle stability during the transition from growth to involution.
research The surface and internal features of pubic hair: A comparative study with those of scalp hair
Pubic hair has a thicker, more protective outer layer than scalp hair, possibly due to evolution.
research Histopathology of aging of the hair follicle
Hair becomes gray and thin as we age, and while most hair loss in older people is due to genetics, there's a chance for gray hair to regain color under certain conditions.
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 Evaluation of Curl Durability for Artificial Hair Fibers
New resin B makes artificial hair fibers hold curls longer than traditional resin A.
research Water-Soluble Polymers in Hair Care
Alkaline hair relaxers damage hair, but cationic and non-ionic polymers can help reduce this damage.
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 Understanding Curly Hair Mechanics: Fiber Strength
Curly hair is mechanically different from straight hair and may need new testing methods.
research Fabrication of a 3D hair follicle‐like hydrogel by soft lithography
Researchers created a 3D hydrogel that mimics human hair follicles, which may help with hair loss treatments.
