This review discusses various environmental pollutants and their potential role in promoting mitochondrial dysfunction, which may contribute to aging-related diseases, cancer, and other adverse health outcomes, but reports no new experimental results.

This study quantified around 60 organic pollutants in hair samples from mothers and infants in Spain, finding significant correlations between pollutant levels and factors like residence, dietary habits, and maternal age, with common exposure sources identified for several pollutant classes.

In this study, the researchers found that a combination of honeys from four islands significantly repaired hair integrity, porosity, and surface roughness caused by UV-A and urban pollution, resulting in strengthened, soft, and shiny hair in Asian hair shafts.

This research highlights that various environmental pollutants, including particulate matter, tobacco smoke, and heavy metals, can significantly affect hair follicle health, linking them to conditions like alopecia areata and androgenetic alopecia, underscoring the need for further study in this area.

In this review, researchers explored how air pollutants increase oxidative stress and inflammation in human skin, affect vitamin D synthesis, and interact with the skin microbiota, also discussing AhR/Nrf2 as a potential target for treating pollution-related skin conditions.

This review discusses how faecal pollution contributes to antimicrobial resistance in surface water and highlights the need for standardized methods and better wastewater management but reports no new clinical results.

In this study, hair samples from dogs with chronic degenerative valve disease showed significantly higher concentrations of certain endocrine-disrupting chemicals compared to healthy dogs, suggesting a potential link that warrants further investigation.

This review discusses the links between particulate matter exposure and skin diseases, highlighting oxidative stress and inflammation as key mechanisms; it reports no new 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.

Goat hair shows changes in metal levels and stress when goats move from indoors to mountain pastures.

This review discusses the various determinants of hair quality in healthy individuals and reports no new clinical results; the authors emphasize the need for independent trials with standardized outcomes.

This review found that synthetic cosmetics pose risks to human health, potentially causing various diseases, and negatively impact ecosystems, air quality, and oceans from production to waste disposal, highlighting the broad environmental and health consequences of cosmetic use.

This chapter provides dermatologists with hair care guidance for alopecia patients and emphasizes that improper handling and chemical processing can worsen hair loss, though it reports no new clinical findings.

Skin aging reflects overall body aging and can indicate internal health conditions.

This article discusses the causes of polycystic ovary syndrome, including environmental pollutants, genetics, and oxidative stress, and explains how these factors contribute to symptoms like irregular menstrual cycles and obesity without reporting new clinical results.

A Western diet may increase acne risk, while a Mediterranean diet and certain supplements can help reduce it.

This study investigated the effects of UV rays and particulate matter on hair porosity, finding that UV exposure increased porosity over time, and when combined with particulate matter, this effect was significantly enhanced in bleached hair.

This dissertation investigates how environmental exposures, such as air pollution and endocrine disruptors, impact women's reproductive and gynecological health throughout life, highlighting associations with earlier menarche, decreased ovarian reserve, and increased PCOS risk, and emphasizing healthcare system shortcomings in properly diagnosing these conditions.

This article discusses the major role of motor vehicles in contributing to urban air pollution and its significant health impacts, especially in developing countries, but reports no new findings.

This study identified a novel Acinetobacter species, strain A1-4-2, with exceptional biodegradation abilities and low antibiotic resistance, found in diverse environments and potentially useful for ecological restoration by degrading organic pollutants.

In this study, canna was identified as the most effective plant for water purification in eutrophic conditions, supplemented by reed, with significant differences in pollutant absorption among the five plant species tested.

This study reviews current research to better understand how various environmental and lifestyle factors, collectively known as the exposome, impact hair health and aging, acknowledging that the detailed mechanisms remain partially understood.

In this survey-based study, researchers reported a high prevalence of hair loss among subjects in Delhi and the National Capital Region and noted widespread unawareness of its dietary, hormonal, genetic, and environmental causes.

This study reported that urban pollution accelerates facial wrinkle development and increases pigmentation severity in Chinese women over 30, whereas UV exposure affects these signs from age 20. After 45, pollution becomes a key contributor to skin aging.

This commentary discusses how environmental epidemiology has largely neglected the impact of racism on health outcomes, suggesting various solutions to better integrate these considerations into research.

This review found that exposure to pollutants like PM, NOx, and PAHs is linked to various skin and hair disorders, indicating a need for cosmetics with natural adsorbents to reduce pollutant effects, achieving 30-55% removal efficiency.

The researchers monitored various pollutants in real cosmetics industry wastewater and reported high removal efficiencies for parameters like Chemical Oxygen Demand and heavy metals through coagulation-flocculation, yet suggested that more effective COD treatment alternatives are necessary to better protect the environment and human health.

This review found that solar radiation, pollution, and trace metals cause significant damage to human hair, with factors like UVB radiation primarily affecting light-colored and bleached hair; most data were derived from in vitro and ex vivo simulations.

This review discusses how acute exposures to environmental and internal stressors can quickly alter skin functions, leading to various dermatological symptoms, and calls for more research on these short-term effects.

This review discusses the impact of air pollution on skin health and suggests that targeting oxidative stress products like HNE could be a new strategy for treating related skin conditions.
