research Color Doppler Ultrasound Pattern of Cutaneous Exosomes at High and Ultra-High Frequency.
Exosome treatments may cause mild inflammation, new blood vessel growth, and hair growth, detectable by ultrasound.
research Three-dimensional microanatomy of mechanoreceptors and their possible mechanism of sensory transduction.
Mechanoreceptors convert physical touch into electrical signals through specialized nerve structures.
research Dorsal skin responses to subchronic ultraviolet B (UVB)-irradiation in Wistar-derived hypotrichotic WBN/ILA-Ht rats.
Prolonged UVB exposure causes significant skin changes and damage in rats.
research Structural abnormalities of the hair shaft
The document concludes that understanding hair structure is key to diagnosing hair abnormalities and recommends gentle hair care for management.
research Sequential cyclic changes of hair roots revealed by dermoscopy demonstrate a progressive mechanism of diffuse alopecia areata over time
Dermoscopy shows that diffuse alopecia areata progresses through specific hair growth stages.
research Water distribution in human hair microstructure elucidated by spin contrast variation small-angle neutron scattering
The technique showed that human hair has two main parts, with 68% being rigid and the rest flexible, and water swelling affects its structure.
research Clinical, Tricoscopic and Histopathological Findings in Mexican Women with Traction Alopecia
Changing certain hairstyles can prevent worsening hair loss in Mexican women.
research Histological Structure of Si Chuan Rabbit Fur and Skin and in Different Procedures
Processing changes Sichuan rabbit skin structure by altering collagen fiber arrangement and porosity.
research Morphological analyses in fragility of pili torti with Björnstad syndrome
Pili torti hair is fragile due to loose keratin filaments and weak disulfide bonds.
research 364 Mechanical forces of human dermal fibroblasts significantly decrease with age
Skin cell strength decreases significantly as we age.
research Investigating the origins of nanostructural variations in differential ethnic hair types using X‐ray scattering techniques
Different ethnic hair types have unique nanoscopic and molecular features despite having the same basic keratin structure.
research Diseases that turn African hair silky
Certain diseases like AIDS and lupus can make African hair become silky.
research Morphological changes in human scalp hair during treatment by hair products containing copper and zinc enriched yeast hydrosylate
Hair products with copper and zinc enriched yeast made hair thicker and denser.
research Alterations in the expression of specific epidermal keratin markers in the hairless mouse by the topical application of the tumor promoters 2,3,7,8-tetrachlorodibenzo-p-dioxin and the phorbol ester 12-O-tetradecanoylphorbol-13-acetate
TCDD changes skin cell growth and keratin production in mice.
research Epithelial–mesenchymal transition in keloid tissues and TGF‐β1 –induced hair follicle outer root sheath keratinocytes
Keloid scars may form due to changes in skin cell characteristics and specific protein signaling.
research The Mineralization of Hair Follicle Tissue
Mineral deposits form in hair follicles after skin injury, faster in rats given DHT.
research ELECTRON MICROSCOPE STUDIES OF HAIR AND WOOL
Hair and wool have complex microscopic structures with microfibrils and varying cystine content.
research Cutaneous manifestation in pregnancy
Pregnant women often experience a variety of skin problems, including pigmentation changes and stretch marks.
research In vivo imaging of mammary epithelial cell dynamics in response to lineage-biased Wnt/β-catenin activation
Activating β-catenin in mammary cells leads to changes that cause early-stage abnormal growths similar to skin structures.
research TYPICAL MORPHOLOGICAL CHARACTERISTICS OF THE SKIN STRUCTURE OF THE HAIR PART OF THE NORMAL HUMAN HEAD AND WITH HAIR LOSS
Androgenic alopecia causes hair follicle degradation and skin restructuring, but some hair elements remain.
research Aging‐associated perifollicular changes and calcium deposition in poodles
Poodles' hair changes aren't always linked to calcium, and special staining is needed to detect true calcium deposits.
research Scanning electron microscopy study of hair shaft changes related to hardness of water
Hard water increases magnesium deposits on hair without changing its structure.
research A novel method for visualizing hair lipids at the cell membrane complex: Argon sputter etching/scanning electron microscopy1
The method shows how hair lipids form specific patterns and their roles in hair structure.
research New Histopathological Findings in Scarring Alopecias
New findings may help diagnose and understand scarring alopecia better.
research Moisture as a Plasticity Switch in Blowouts: Glass-Transition Behavior, Viscoelastic Response, and Tension-Defined Shape
Moisture makes hair flexible for reshaping during blowouts.
research Lipid loses and barrier function modifications of the brown‐to‐white hair transition
White hair has less lipid content and absorbs water differently than brown hair.
research Skin aging as a mechanical phenomenon: The main weak links
Skin aging is largely due to differences in stiffness and elasticity between skin layers, leading to wrinkles.
research Hair Morphology in Androgenetic Alopecia
Abnormal cuticle and hair shaft medulla cause hair loss in androgenetic alopecia; sonography helps diagnose and manage it.
research Phenotypic modulation of human hair matrix cells (trichocytes) by environmental influence in vitro and in vivo.
Human hair cells can change based on their environment, especially interactions with certain skin cells.
