390-420 / 1000+ resultsresearch Effect of shampoo, conditioner and permanent waving on the molecular structure of human hair
Perming significantly changes hair's molecular structure, while shampoo and conditioner do not.
research Recent advances in X-ray microanalysis in dermatology.
Trace elements like calcium, iron, and zinc are unevenly distributed in hair, while sulfur is even, and increased phosphorus and potassium levels are linked to skin reactions.
research A Study of Aggregation Structures and Tensile Properties of Hair Fibers
research The changing patterns of hair density and thickness in South Korean women with hair loss: clinical office-based phototrichogram analysis
South Korean women with hair loss have lower hair density and thickness compared to healthy women.
research 252 Follicle dermal papilla cells undergo chromatin remodelling processes in vivo and in vitro
Hair follicle cells change their DNA packaging during growth cycles and when grown in the lab.
research Basement membrane changes in lichen planopilaris
Basement membrane changes in lichen planopilaris cause scarring and permanent hair loss.
research Tissue Mechanics in Haired Murine Skin: Potential Implications for Skin Aging
Older mice have stiffer skin with less elasticity due to changes in collagen and skin structure, affecting aging and hair loss.
research X-ray diffraction study of the nanostructural dynamics of fibrillar systems of hair tissue
Hair tissue can help monitor environmental and public health risks.
research Longitudinal biomarker trajectories accompanying trichoscopic change after PRP-based regimens for alopecia: a complementary multi-marker analysis of a real-world cohort.
PRP-based treatments can increase hair density, but results vary among individuals.
research Ultrastructural visualization of cross-linked protein features in epidermal appendages
Cross-linked proteins help maintain the structure of hair, feathers, and hagfish teeth.
research A clinical study of skin changes in geriatric population
Older adults commonly experience wrinkles, itchy skin, psoriasis, fungal infections, skin growths, grey hair, hair loss, and nail ridging, but no skin cancer was found in this group.
research Trichoscopic spectrum of follicular and scalp changes following hair transplantation
This study explores the use of trichoscopy in monitoring post-hair transplantation changes in six patients. It highlights that at 1 month post-transplant, perifollicular erythema and scaling are prominent. By 6 months, there is a consistent accentuation of follicular ostia with a perifollicular gray-white halo, alongside various hair shaft abnormalities throughout the post-transplant period. The findings suggest that trichoscopy can be valuable in assessing surgical outcomes and detecting complications early in the post-transplant setting.
research Scanning electron microscopy and morphometric analysis of the hair in dromedaries with SEM-EDX in relation to age
Dromedary camel hair structure and mineral content change with age.
research Analysis of Morphological Changes on the Hair Surface by Heat Perm Treatment Method
Direct heat perms cause more damage to hair than softening heat perms.
research 1299 Live imaging of keratin network in stratum granulosum reveals dynamic cytoskeletal changes during cornification in mice in vivo
The keratin network in mouse skin changes during cornification and affects the skin's protective barrier.
research Physiological changes in the skin during pregnancy
Pregnancy can cause skin pigmentation, stretch marks, and changes in hair, nails, and sweat glands, with most resolving after birth.
research Tactile and hair-hair friction behavior of hair fibers
Hair feels different when touched and rubs together in various ways.
research Heterozygous Arrhythmogenic Cardiomyopathy-desmoplakin Mutation Carriers Exhibit a Subclinical Cutaneous Phenotype with Cell Membrane Disruption and Lack of Intercellular Adhesion
Carriers of a specific gene mutation have subtle skin changes without visible symptoms.
research Measuring changes in chemistry, composition, and molecular structure within hair fibers by infrared and Raman spectroscopic imaging
Infrared and Raman imaging can non-destructively analyze hair structure and help diagnose hair conditions.
research Spatiotemporal dynamics of sensory neuron and Merkel-cell remodeling are decoupled during epidermal homeostasis
Sensory neuron remodeling and Merkel-cell changes happen independently during skin maintenance.
research Epithelial‐to‐mesenchymal transition in cutaneous wound healing: Where we are and where we are heading
The document concludes that a better understanding of cell changes during wound healing could improve treatments for chronic wounds and other conditions.
