Rice derivatives in conditioners protect and improve hair health.
research Synthetically programmed antioxidant delivery by a domesticated skin commensal
Engineered bacteria can deliver antioxidants to protect skin.
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 Reproduction Mechanism of SS Cross-Links in Permed Hair by the Washing after Reduction with Thioglycolic Acid
Washing permed hair after using thioglycolic acid helps reform strong bonds, making hair stronger.
research A Raman spectroscopy investigation of the resilience of hair cuticular scales under uniaxial stress
Hair cuticles remain stable and resilient under stress due to strong protein content and crosslinking.
research Détection précoce de la cardiotoxicité due à la doxorubicine chez le miniporc par imagerie par résonance magnétique
Doxorubicin causes heart damage, so early detection and monitoring are important during chemotherapy.
research Accessing Properties of Molecular Compounds Involved in Cellular Metabolic Processes with Electron Paramagnetic Resonance, Raman Spectroscopy, and Differential Scanning Calorimetry

research 616 Endoplasmic reticulum stress upregulates NKG2D ligands in the hair follicle
Stress in hair follicle cells increases certain immune-related proteins, which might contribute to hair loss conditions.
research Stress and Psychoneuroimmunologic Factors in Dermatology
Stress and emotional factors can worsen skin conditions by affecting the immune system.
research Association between stress and bilateral symmetrical alopecia in free-ranging Formosan macaques in Mt. Longevity, Taiwan
Stress is likely causing hair loss in Formosan macaques.
research Chronic Restraint Stress Inhibits Hair Growth via Substance P Mediated by Reactive Oxygen Species in Mice
Chronic stress can cause hair loss by increasing oxidative stress, but antioxidants may help.
research Persistent escalation of alcohol consumption by mice exposed to brief episodes of social defeat stress: suppression by CRF-R1 antagonism
Blocking CRF-R1 can reduce alcohol intake in stressed mice.
research Neurosteroidogenesis Is Required for the Physiological Response to Stress: Role of Neurosteroid-Sensitive GABAAReceptors
Neurosteroids are crucial for stress response, and targeting specific receptors may help treat certain disorders.
research OBESITY-RELATED FACTORS INVOLVED IN ENDOPLASMIC RETICULUM STRESS INDUCTION IN ADIPOCYTES
Adipose tissue changes in obesity can trigger stress in fat cells.
research Biological characteristics of age-related changes in C57BL/6 mice sub-strains in the national center for geriatrics and gerontology aging farm
B6J mice live longer before 24 months, but B6N mice live longer after; both strains show weight gain, increased food and water intake, and health issues as they age.
research Interaction of chronic ethanol exposure and finasteride: sex and strain differences
Finasteride reduces alcohol withdrawal effects, especially in female mice.
research Disulfide Cross-Linked Network Structure of Intermediate Filament and Matrix in Hair and Wool Cortices
Hair and wool strength is affected by the number and type of bonds in their protein structures, with hair having more protein aggregates than wool.
research Possible relationships between the physical conditions of cattle and the occurrence of structural modifications of their coat hair
Vitamin A deficiency changes cattle hair structure, while pregnancy may improve it, suggesting hair can indicate cattle health.
research Reimagining Hair Science: A New Approach to Classify Curly Hair Phenotypes via New Quantitative Geometrical & Structural Mechanical Parameters
New methods to classify curly hair types were developed based on shape and strength.
research Biology of the wool follicle: an excursion into a unique tissue interaction system waiting to be re‐discovered
The article concludes that the wool follicle is a valuable model for studying tissue interactions and has potential for genetic improvements in wool production.
research TELOGEN EFFLUVIUM: AN ETIOPATHOGENETIC THEORY
The paper suggests that telogen effluvium, a type of hair loss, may be a long-lasting condition triggered by stress or illness in people whose hair growth is unusually synchronized.
research Corticosterone inhibits GAS6 to govern hair follicle stem-cell quiescence
Stress hormone corticosterone blocks a growth factor to slow down hair stem cell activity and hair growth.
