This review discusses age-related changes in scalp skin and their potential effects on hair follicle aging, but reports no new clinical results, calling for further investigation.

This article discusses the genomic and postgenomic changes in chronic degenerative diseases and cardiovascular and skin disease contexts, highlighting potential modulation through diet and pharmacological interventions without presenting new experimental results.

This review discusses the complex mechanisms behind acne vulgaris and suggests that dietary modification, along with pro- and prebiotics, may influence its pathogenesis by addressing stress-induced skin inflammation.

This review discusses the potential immuno-regenerative effects of polydioxanone threads in hair loss treatment, focusing on tissue responses and immune modulation, but does not report clinical results.

This review discusses how urban air pollutants may influence the regulation of JAK3 signaling in alopecia areata and reports no new experimental results; the authors integrate existing data to map potential pathways and biomarkers.

This study found that finasteride and minoxidil act as hormone disruptors in mice, with finasteride having a more significant association with reproductive injuries, such as damage to the epididymis and reduced semen volume.

Women with telogen effluvium have an imbalance in thiol-disulphide, suggesting oxidative stress may contribute to hair loss.

This review found a significant association between smoking and androgenetic alopecia, but notes a lack of studies on whether quitting smoking can improve hair loss.

This study explored the molecular factors behind delayed wound healing in obesity, highlighting that systemic changes like inflammation and collagen deposition alterations contribute to sustained skin inflammation and reduced mechanical resistance.

This article reviews potential pathomechanisms of vitiligo, emphasizing membrane alterations involving cholesterol and cardiolipin, but reports no new clinical findings.

This study found that UVB radiation primarily causes hair protein loss, while UVA radiation mainly contributes to hair color changes, with no significant differences in mechanical properties observed between photooxidized and non-irradiated hair.

This study found that the systemic wrinkled skin phenotype in Xiang pigs involves gene expression changes and genetic variations associated with oxidative stress and extracellular matrix components, resembling features seen in Shar-Pei dogs.

This study found that non-infectious skin conditions in sheep were associated with oxidative stress and changes in trace elements, vitamin A, and immunoglobulin levels.

In this study, 15d-PGJ2 administered in a topical cream inhibited oxidative and inflammatory skin changes caused by UVB radiation in hairless mice, suggesting it as a promising treatment approach.

In this study, researchers investigated age-related hearing loss in advanced-age CBA/CaJ mice and found combined cochlear damage from chronic sound exposure and metabolic changes linked to oxidative stress, which may require addressing both etiologies for prevention and treatment.

In this study, researchers explored how hypoxic preconditioning affects the survival and oxidative stress resilience of nestin-expressing hair follicle stem cells and SH-SY5Y neuroblastoma cells, focusing on changes in gene expression for HIF1α, BDNF, and VEGF.

This review explores how radiation-induced hair graying can be used as a model to study the mechanisms behind hair graying, focusing on cellular senescence and potential therapeutic targets to address age-related changes. Results are not provided.

This study found that administering dutasteride did not change spermatogenesis or oxidative stress levels in rat testes, though further research is needed to confirm these findings.

This research review found that climate change exacerbates skin conditions like photoaging, inflammatory dermatoses, and skin cancers by causing oxidative stress and inflammation, suggesting that dermatological practices should incorporate environmental and multicultural considerations to optimize patient outcomes in diverse populations.

This study analyzed the swelling behavior of human hair during permanent waving treatment, finding that both the microstructure and macrostructure of intermediate filaments swell simultaneously at the initial stage, and while partially destructed by reduction, they are considerably restored through oxidation.

This study found that in SAMP8 mice, phenotypic changes in outer hair cells or the stria vascularis, possibly due to oxidative deficiencies, may predict variability in age-related hearing loss before outer hair cell loss occurs.

This study identified changes in immune activation, ferroptosis, and structural genes in alopecia areata subtypes, suggesting molecular markers that might help understand disease variability and guide future treatments.

This study observed that cashmere production and secondary hair follicle activity in Inner Mongolian ewe goats showed age-related differences, with younger goats (aged 2-4 years) having greater production and follicle activity correlating positively with higher antioxidant capacity and lower oxidative stress.

PCOS management includes lifestyle changes and medications to improve fertility.

This study found that oxidized hair undergoes time-related structural changes, resulting in improved thermal and mechanical stability over several months after moderate or intense oxidative treatments.

In this study, researchers observed distinct aging signatures in mouse keratinocytes, with increased expression in older mice, and noted relevant pathway changes that were also evident in human skin, suggesting potential insights into intrinsic skin aging.

The researchers reported that human hair keratin films exhibit color changes and reduced protein solubility after thermal treatments, suggesting their potential use in evaluating hair thermal damage instead of actual hair samples.

Hair coloring and bleaching can permanently break down hair protein and temporarily change its properties.

This study found that both ethanol and aqueous extracts of Lepidium sativum seeds improved insulin signaling and reduced obesity-related metabolic changes in high-fat diet-fed rats, suggesting potential as a dietary supplement.

In this mouse study, UVA and UVB exposure led to hair follicle miniaturization, graying, and prolonged hair cycle duration, associated with changes in stem cells and increased Wnt signaling activity.
