This review discusses the adverse effects of hair care products, highlighting irritation dermatitis and allergic contact eczema due to common allergens like paraphenylenediamine and glycerol monothioglycolate, but reports no clinical results.

This review discusses the potential antiandrogenic effects of environmental chemicals on reproductive development, highlighting concerns about their impacts on humans but reports no new clinical findings.

This review highlights concerns about the potential negative effects of chemicals in cosmetic products on the health of pregnant women, fetuses, and newborns, stressing the need for more research.

This study found that plastic factory staff in Sirjan, Iran were exposed to microplastic particles through various body receptors, with hair having the highest particle count and saliva the lowest.

This article highlights the health risks associated with adding paraphenylenediamine to mehndi, such as contact dermatitis and asthma, and emphasizes the need for regulatory checks as its use grows among cancer patients, women with alopecia, and pregnant individuals.

This article reviews the risks of metal exposure from cosmetic products and emphasizes the need for stricter regulation and consumer awareness, without presenting new data or results.

This study investigated the ability of a human hair keratin dimer to absorb the pollutants diclofenac and perfluorobutane sulfonate, finding high binding affinities that suggest potential for hair-derived materials in water filtration technologies.

The moisturizer with phytol improved skin texture and reduced fine wrinkles better than the moisturizer without it.

This study explored using keratin extracted from human hair waste to create biodegradable bioplastic films, revealing promising potential for applications in packaging and disposable items due to their uniform surface morphology and ability to degrade with keratinophilic fungi.

This study investigated a nanostructured system using PS-b-PAA diblock copolymer for incorporating the hydrophobic photosensitizer ClAlPc, finding it effective in causing cellular damage in Caco-2 cells under light while demonstrating no cytotoxicity without light, suggesting its potential use in photodynamic therapy.

This study found that while short-term use of PEG-400 and Thiazone affected rat skin structure, the changes were reversible with no long-term effects observed.

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 study found that a single application of TCDD on the skin of hairless mice altered epidermal differentiation, changing keratin expression patterns similarly to a known tumor promoter.

This article reviews the development, classification, and embryology of hypospadias and reports no new findings; the authors highlight its unknown cause and discuss associated anatomical anomalies.

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 study found that TCDD significantly reduced EGF receptor binding in various animal models, linked to toxic symptoms like weight loss and developmental delays, with receptor phosphorylation persisting several days.

In this study, TCDD administered to male rats down-regulated EGF receptor in liver plasma membranes and increased protein kinase activity, suggesting EGF receptor–mediated toxicological effects.

In this study, low-dose BPA was associated with induced prostatic hyperplasia in rats, potentially mediated by COX-2 and L-PGDS through pathways involving cell proliferation and apoptosis.

In this study, researchers investigated the penetration and cellular responses to nanoplastics in human skin models with compromised barriers, finding that nanoplastics can penetrate the skin, accumulate in cells, and trigger inflammatory responses through specific signaling pathways.

This study found that gelatin-resorcinol-formaldehyde caused peritoneal lesions and hair loss in rats and mice, indicating it is unsuitable for tubal occlusion and emphasizing the need for testing in multiple species before using compounds in humans.

In this study, a single oral dose of 2,3,4,7,8-pentachlorodibenzofuran in male Fischer rats led to dose-dependent toxicity, resulting in weight loss, hepatotoxicity, and mortality.

This study explored the potential of human hair keratin as a filtration material, finding that it may effectively absorb the pollutants diclofenac and perfluorobutanesulfonate. The researchers reported significant binding affinities through molecular simulations, supporting further investigation into keratin's use for water purification.

This study found that prenatal exposure to fluoride and lead, as well as maternal micronutrient intake, may influence sexual maturation in adolescents in a sex-specific manner.

Diphenyl ethers can potentially reduce excess oil production when applied on the skin, helping treat conditions like acne.

This study observed very high thallium levels in small mammals near a zinc smelter in Poland, accompanied by severe population and health impacts.

In this study, commercial synthetic braiding hair samples from Kenya were analyzed, revealing that while no Ammonium Thioglycolate was detected, significant formaldehyde contamination was present, with varying concentrations throughout the hair strands, potentially impacting consumer safety.

This review discusses temporary chemical hair removal methods involving thioglycolates and other compounds but reports no new clinical findings; the authors highlight interest in natural-based substances.
