This narrative review identifies telogen effluvium as a growing concern linked to weight-loss interventions, such as GLP-1 receptor agonists and bariatric surgery, attributing hair loss to systemic and metabolic stress rather than permanent hair follicle damage.

This study found that some white or grey human hairs can naturally regain pigmentation, suggesting a potential temporary reversibility of hair greying associated with stress and molecular changes.

In this study, researchers observed that acute stress increased levels of the enzyme 5αR2 in the medial prefrontal cortex of male rats, affecting stress reactivity, but this effect was not seen in females.

This review discusses the role of jasmonic acid and its conjugates in enhancing plant stress tolerance and balancing growth and defense mechanisms but provides no new experimental data.

This article reviews various causes of hair loss linked to systemic factors, noting that careful history and examination can lead to accurate diagnosis, but reports no new clinical results.

This study found that Foxp1, a transcriptional factor, plays a key role in regulating hair follicle stem cell proliferation by modulating oxidative stress and the cell cycle during hair growth phases.

This review evaluates photobiomodulation's diverse clinical uses in sports and medicine, reporting physiological modulation and potential therapeutic benefits, but emphasizes the importance of precise dosimetry for success.

This background review discusses alopecia areata, highlighting the role of CD8+NKG2D+ T cells in hair follicle pathogenesis, and notes that the exact mechanisms causing hair loss remain unclear.

This review discusses the role of lamins in development, tissue maintenance, and stress response, and does not report new experimental findings.

This study suggests that in late pregnancy, allopregnanolone induces opioid inhibition of oxytocin secretion in response to immune challenge, potentially minimizing the risk of preterm labor in rats.

This study reported that visceral massage improved skin elasticity and metabolic indicators such as glucose and lipid levels, suggesting its potential as a non-invasive method for enhancing skin health and systemic metabolism.

This study found that hair cortisol concentration in free-ranging brown bears is influenced by handling methods, body condition, and potentially both short- and long-term stressors.

This study explores the potential of adaptogenic herbal extracts like ashwagandha, rhodiola, and schisandra in treating stress-induced dermatoses, noting their effects on modulating the HPA axis, reducing inflammation, and improving skin barrier function.

This review summarizes the various skin manifestations linked to COVID-19 infection, vaccination, and personal protective equipment, highlighting their clinical importance and discussing psychological stress and social isolation as additional dermatologic factors.

This article reviews potential factors influencing Behçet's disease, like increased neutrophil functions, immunological changes, stress, and hormonal alterations, but it presents no new clinical results.

This study discovered that the circadian clock influences hair follicle regeneration, making hair grow faster in the morning and causing more radiation-induced hair loss in the morning compared to the evening.

This review discusses the synthesis and biological activities of jasmonates, highlighting their potential as drugs and prodrugs, but reports no new clinical results; further research and trials are anticipated.

This review discusses the mechanisms and treatment strategies for age-related hair changes, such as androgenetic alopecia and hair graying, and reports no new clinical results.

This study found that cotreatment with graphene oxide and indole-3-acetic acid significantly inhibited root development in Brassica napus, with the inhibition increasing as indole-3-acetic acid concentration rose.

In this rat study, offspring from females fertilized by finasteride-treated males showed hyperglycemia and increased hepatic glycogen, linking paternal androgen imbalance to liver issues across generations.

This review identifies shared interferon gamma-driven immune pathways in vitiligo and alopecia areata, revealing potential targets for new treatments, but reports no clinical results.

This study reviewed the physiological and psychological impacts of acne vulgaris, highlighting its complex interactions with endocrine issues, sebum production, and immune response, while suggesting that a multidisciplinary approach can inform future treatments and improve quality of life for those affected.

This review discusses the formation and structure of the cornified cell envelope in the epidermis, highlighting biochemical pathways and genetic factors, but presents no new experimental results.

This review investigates how selenium, a trace element found in wheat, may impact hair health by examining its biochemical role in hair follicle biology and its potential therapeutic and toxicological effects.

The authors concluded that low energy laser therapy may serve as a useful complementary treatment for skin diseases such as lichen planus, infectious finger pulpits, scalp alopecia, and crural ulcers.

This review discusses alopecia areata as a model for studying tissue-directed autoimmune diseases and reports no new clinical findings.

This study suggests that COVID-19 infection may trigger telogen effluvium, a condition of hair shedding, though medication side effects and pandemic-related stress cannot be excluded as contributing factors.

This study observed that telogen effluvium was the most common form of acquired alopecia among females in a semiurban Indian population, with stress and chemical exposure as major exacerbating factors.

In this systematic review, animal studies showed that cytarabine causes multi-organ toxicities, notably neurotoxicity, linked to oxidative stress and other mechanisms, though study quality raises concerns about reliability and translation to human outcomes.

This study found that Muse cells, when injected subcutaneously, alleviated symptoms of atopic dermatitis in mice, suggesting potential for treating inflammatory skin conditions.
