840-870 / 1000+ results research L'idea di fenomeno fra Kant ed Husserl
Increased Wnt signaling causes hair graying by depleting melanocyte stem cells in aged mice.
research Bayesian measurement-error-driven hidden Markov regression model for calibrating the effect of covariates on multistate outcomes: Application to androgenetic alopecia
Model improves accuracy in predicting hair loss effects.
research Clinical Snippets
Melanoma risk tools need improvement, a gene mutation causes a hair disorder that might be treated by managing cell stress, a potential therapy for a skin-ear disorder involves blocking cell channels, skin wrinkling may indicate lung aging regardless of smoking, and oxidative stress might contribute to common baldness.
research Global and exponential stabilization of a chemotactic alopecia areata model with signal-dependent diffusion and sensitivity
Reducing CD8+ T cell growth can stabilize alopecia areata.
research Establishing a robust preclinical model to investigate early and late radiation-induced skin reactions
The model effectively mimics radiation-induced skin damage for future research.
research Loose anagen hair syndrome in two patients with epidermolysis bullosa simplex, Dowling-Meara type
Two patients with the same genetic mutation had both blistering skin and easily pulled out hair.
research Hair follicle aging is driven by transepidermal elimination of stem cells via COL17A1 proteolysis
Hair loss is caused by the breakdown of a protein called COL17A1 in hair follicle stem cells.
research Fundamental studies on the interaction between moisture and textiles. Part X. Moisture sorption properties of wool and hair fibers.
Wool and hair fibers absorb moisture similarly due to their keratin structure, with the amount of non-crystalline areas affecting the moisture uptake.
research Reviewer #3 (Public Review): Spatiotemporal dynamics of sensory neuron and Merkel-cell remodeling are decoupled during epidermal homeostasis
Sensory neuron changes and Merkel-cell changes in the skin happen independently during normal skin maintenance.

research Modeling Oxidative Stress–Linked Telogen Effluvium: A Monte Carlo Simulation Using Published Trichoscopy Norms and Cannabis Exposure Distributions
Higher cannabis use may be linked to more severe hair loss.
research A model for the turnover of dihydrotestosterone in the presence of the irreversible 5α-reductase inhibitors GI198745 and finasteride
Both drugs lower DHT levels, with GI198745 being more effective.
research Skin Ageing in Women: Pathophysiology and Treatment
The document concludes that skin aging in women can be caused by UV exposure and hormonal changes, and treatments like hormone replacement therapy and various skin therapies can help.
research ToF‐SIMS characterization of the lipid layer on the hair surface. II : Effect of the 18‐MEA lipid layer on surface hydrophobicity
18-MEA is essential for hair's water resistance, and a conditioner with 18-MEA and SPDA can restore it.
research General theory of skin reinforcement
Skin and its underlying fat layer act together to resist mechanical stress, and reinforcing this composite structure may help more with anti-aging than just strengthening the skin alone.
research Modeling Dynamic Hair as a Continuum
The authors created a realistic and efficient method to simulate hair movement by combining fluid dynamics with individual hair strand behavior.
research Expression of Wnt Genes in Echinaster Sepositus Arm Regeneration
Wnt genes help starfish regrow arms by aiding wound healing and cell development.
research Structural changes in the trichocyte intermediate filaments accompanying the transition from the reduced to the oxidized form
Oxidation changes the structure of hair protein filaments, causing them to compact and rearrange.
research Machine learning predicts scarring progression in lichen planopilaris: A multidimensional model integrating trichoscopy, vitamin D, and diagnostic timelines
A machine learning model can predict scarring in lichen planopilaris using factors like vitamin D levels and diagnostic delay.
research Age-Induced Hair Graying and Oxidative Stress
research Aging Skin: A Window to the Body
Skin aging reflects overall body aging and can indicate internal health conditions.
research Inhibition of 5α-Reductase, IL-6 Secretion, and Oxidation Process of Equisetum debile Roxb. ex Vaucher Extract as Functional Food and Nutraceuticals Ingredients
Equisetum debile extract, especially the ethyl acetate type, may be a promising natural ingredient for anti-hair loss products.
research Frontal Fibrosing Alopecia and the Role of Cosmeceuticals in Its Pathogenesis
Cosmeceuticals like sunscreens may trigger frontal fibrosing alopecia, but more research is needed.
research Investigation of aging effects in human hair using atomic force microscopy
Aging makes hair thinner and rougher, with less clear edges.
research Dual Case Reports for Lipid Loss from Human Hair
Changing hair's surface and structure can help protect its natural oils from being washed away.
research Effects of UV Induced-Photoaging on the Hair Follicle Cycle of C57BL6/J Mice
UV exposure causes hair thinning, graying, and changes in hair growth cycles in mice.
research Intrinsic versus Extrinsic Aging: A Histopathological, Morphometric and Immunohistochemical Study of Estrogen Receptor β and Androgen Receptor
The study concluded that both estrogen and androgen receptors, which decrease with age, are linked to skin aging and may be hormonally regulated.
research Fluid Loss Through Epidermis of the Rat and Factors Affecting It.
Fluid loss through rat skin is minimal when inactive but increases with skin activity and hair growth.
research The kinetics of moisture sorption by hair
Hair absorbs moisture differently based on its structure and treatment, with changes occurring at 30% humidity.
