780-810 / 1000+ resultsresearch Impact of ultraviolet radiation‐induced damage to hair fiber integrity: A multi‐technique physicochemical characterization of surface and cortex properties
UV radiation damages hair similar to bleaching, but double bleaching causes more severe protein degradation.
research Nucleation and growth of macrofibrils in trichocyte (hard-α) keratins
Sheet formation is key to macrofibril structure differences in wool.
research Existence of various structural zones in keratinous tissues revealed by X-ray microdiffraction
Keratinous tissues have multiple structural layers, including ordered keratin and lipid granules.
research 289 Immortalization of primary human dermal papilla cells by Bmi-1 and TERT
Hair care products reduced hair roughness, a combination of Stemoxydine and Resveratrol increased hair density, fermented mackerel oil promoted hair growth, and genes TERT and Bmi-1 helped create new hair follicles.
research ToF‐SIMS characterization of the lipid layer on the hair surface. I: the damage caused by chemical treatments and UV radiation
Chemical treatments and UV radiation severely damage the lipid layer on hair.
research تصميم غطاء عالي الكفاءة لحماية الشعر من ملوثات الطقس
A well-designed cap can protect hair from weather pollutants and sun damage.
research Synthesis of a new amino acid derivative with long‐lasting hair shape control effects and elucidation of its mechanisms
A new amino acid derivative, ATS, improves hair texture and moisture, making it easier to straighten curly hair.
research Analysis of structural changes in permanent waved human hair using Raman spectroscopy
Permanent waving weakens hair by altering its protein structure.
research Heterotypic cell contacts and basal lamina morphology during hair follicle development in the mouse: a light, scanning, and electron microscopic study at the site of tissue interaction
Heterotypic cell contacts likely help hair matrix cells differentiate during mouse hair follicle development.
research Ziehl-Neelsen's stain for skin sections to show wool and hair follicles
Ziehl-Neelsen's stain helps identify different parts of hair in sheep and goats.
research High spatial resolution study of human skin using synchrotron infrared microscopy: application to the penetration of external agents
External agents penetrate skin more easily in areas with fewer lipids, especially through hair follicles.
research In vivo silica nanoparticle translocation across human stratum corneum: the effect of surface hydrophobization in relation to hair follicle density.
Hydrophobized silica nanoparticles penetrate the skin's outer layer more effectively, while hair follicle density doesn't impact their accumulation.
research Self Organized Skin Equivalent by Epithelial and Fibroblast Cells on Polycaprolactone Electrospun Mat with Porous Fibers
Researchers created a potential skin substitute using a biodegradable mat that supports skin cell growth and layer formation.
research Evaluation of a novel hybrid polymer in hair treatment
The new polymer improves dyed hair's color, moisture, shine, and smoothness.
research The Role of Interface Geometry and Appendages on the Mesoscale Mechanics of the Skin
Skin's uneven surface and hair follicles affect its stress and strain but don't change its overall strength, and help prevent the skin from peeling apart.
research Strontium: A Potent and Selective Inhibitor of Sensory Irritation and Topical Anti-inflammatory
Strontium can effectively reduce skin irritation and inflammation.
research Hair weathering and hair capacitance mapping: a pilot study
Hair capacitance mapping effectively measures hair surface moisture changes.
research Characterization of surface deposits on human hair fibers
research In vitro evaluation of changes of hair fibers subjected to oxidation-reductive straighteners associated with dyeing
Straightening and dyeing damage hair structure.
research Wetting behavior of human hair fibers
Human hair's ability to get wet is complex and can change with treatments, damage, and environment.
research “TRICHOASSIST” Trichogram Hair and Scalp Feature Extraction and Analysis Using Image Processing
"TRICHOASSIST" is a system that analyzes hair and scalp images to help diagnose scalp diseases.
