research Case report: Exploring autosomal recessive woolly hair: genetic and scanning electron microscopic perspectives on a Japanese patient
A genetic mutation in the LIPH gene causes tightly curled hair that stops growing in some Japanese individuals.
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.
research Preparing the hair follicle canal for hair shaft emergence
A specific type of skin cell creates an opening for hair to grow out, and problems with this process can lead to skin conditions.
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 Microscopic Hair Changes Associated with Hair Coloring, Hair Waving and Hair Ironing in Iranian Women
Hair coloring, waving, and ironing cause more hair damage than not using these treatments.
research Morphological Changes of Human Hair Related to "Graying".
Gray hair affects hair's movement and appearance, making it less bouncy and more wavy.
research Cross-linked features of mouse pelage hair resistant to detergent extraction
Some mutant mice have hair with abnormal cross-linking, mainly in the cuticle, not affecting other hair parts.
research P5 Assembly of hair keratins in thansfected cultured cells
research Reactive keratin derivatives: A promising strategy for covalent binding to hair
Modified keratin binds better to hair, especially bleached hair.
research Evaluation of the predictive capacity of DNA variants associated with straight hair in Europeans
Certain DNA variants can predict straight hair in Europeans but are not highly specific.
research Cosmetic Products and Hair Health
Healthy hair is crucial to avoid dryness, weakness, and breakage.
research Prospective ultramorphological characterization of human hair by optical coherence tomography
OCT can identify hair structures, but chemical treatments can damage them.
research Preparation of human hair keratin/calcium alginate blend films
More human hair protein makes the films weaker and less clear.
research Structural change of keratin protein in human hair by permanent waving treatment
Permanent waving damages hair by disrupting its keratin structure.
research Analyzing the laser-light reflection from human hair fibers. I. Light components underlying the goniophotometric curves and fiber cuticle angles.
The research found a way to measure hair surface changes by analyzing how light reflects off of it, and determined hair cuticle angles vary by hair length and color.
research Optical coherent tomography: promising in vivo measurement of hair shaft cross section
OCT is a reliable, noninvasive way to measure hair thickness.
research Element profiles of mouse hair: A concern for using hair as a timetable repository
Mouse hair element patterns vary, making it unreliable for tracking time.
research Hair casts or pseudonits
Hair casts, also called pseudonits, are often mistaken for other conditions.
research Miscellaneous Disorders
Trichorrhexis nodosa causes hair to break easily, often affecting young to middle-aged black women.
research In-Situ Tensile Testing of Hair Fibers in An Environmental Scanning Electron Microscope (ESEM)
Hair fibers break by cuticle cell slipping, shape changing, cuticle fraying, and surface cracking when stretched under specific conditions.
research Quantifying variation in human scalp hair fiber shape and pigmentation
African hair is curled, Asian hair is thick, European hair is lighter, and chemical methods help identify hair color differences.
research Hair today, gone tomorrow: the degradation and conservation of archaeological hair fibers
Acidic sandy clay damages archaeological hair the most, while dry conditions preserve but make it brittle; silicone oil can help keep the hair flexible.
research Follicular Bisection in Hair Restoration: In Vivo Experiment
Splitting one hair follicle into two can help regrow hair with a 50% to 70% success rate, useful when donor hair is limited.
research Hair Follicle Transglutaminases and the Formation of ε-(γ-Glutamyl) Cross-links
Transglutaminases help form strong hair by linking proteins, and can potentially alter hair properties.
research Spectral histology of hair and hair follicle using infrared microspectroscopy
Infrared techniques reveal glycogen, unsaturated lipids, and calcium compounds in hair.
research Cyclic hair-loss and regrowth in transgenic mice overexpressing an intermediate filament gene.
Mice with extra sheep genes had hair that fell out and regrew in cycles.
research Improvement in Hair Loss and Better Hair Quality with Vitamin Therapy in Monilethrix
Taking vitamins, minerals, and amino acids can improve hair strength and quality in people with Monilethrix.
research Histological and dermatoscopic description of sphynx cat skin
Sphynx cats have abnormal hair follicles and keratinization affecting their skin.
research [Studies on monilethrix].
Monilethrix is not caused by a metabolic defect.
