This study found that the reproductive function of female hairdressers may be negatively affected by long-term exposure to permanent-waving solutions containing thioglycolic acid, raising concerns about its potential carcinogenic effects.

This study found that poly(butylene citramalate-co-butylene succinate) copolymers exhibit high toughness, recyclability, degradability, and biocompatibility, achieving complete wound healing with skin and hair follicle regeneration in 7 days.

This study found that adverse reactions to para-phenylenediamine in hair dye, including severe allergic contact dermatitis, may be more common than currently reported and often misdiagnosed.

This study found that polymers significantly improved the chemical and microbial stability of steroid hormones in liposome formulations over eight weeks, with finasteride showing the highest diffusion rate.

This review discusses the need for an updated 'European hair cosmetic series' to include common contact allergens and remove outdated substances based on current evidence and regulations, but it reports no new results.

This study found that most milk powder samples tested from the Romanian market contained element concentrations exceeding legal limits, especially potassium, calcium, chlorine, phosphorus, and aluminum.

This infographic compares the safety profiles of SH‑1, a cosmetic ingredient, which showed no systemic absorption, and PP405, an investigational drug with dose-dependent systemic uptake and potential threshold breaches, highlighting differences in safety between cosmetic and investigational substances according to this report.

This study suggests that geranyl acetate may offer protective, anti-inflammatory, and cytoprotective effects against PPD-induced toxicity in keratinocyte cells, indicating its potential as a plant-derived treatment.

In this study, PFOS exposure altered steroid hormone levels and enzyme activities related to steroidogenesis in juvenile Silurana tropicalis, with effects differing between male and female frogs.

This study found that CD1a-restricted CD4+ T cells responsive to lysyl-phosphatidylglycerol were more frequent in the blood of atopic dermatitis patients, suggesting a potential role in the disease's Th2-mediated pathology.

This study found that 9% of tested patients had positive patch test reactions linked to hair care products, with most reactions clinically relevant and commonly involving allergens like p-phenylenediamine.

This study found that specific TRPM5 modulators are unlikely to directly affect sebaceous glands, but safe TPPO analogues may provide moderate lipogenic and anti-inflammatory effects beneficial for dry skin conditions.

This review discusses the use of human and animal-derived placental and umbilical extracts in cosmetics, highlighting insufficient data to establish their safety and recommending they should not have metabolic or endocrine activity.

This study observed that exposure to heavy metal salts affected skin and hair morphology in mice, with lead acetate decreasing keratinocyte proliferation and zinc sulfate and sodium dichromate increasing it.

This study developed a sensor that effectively measures Tl+ cation in solutions with a wide dynamic range and low detection limit, responding linearly within the concentration range 1.0 × 10−8 to 1.0 × 10−1M.

This study found that PLDζ2 and NPC4 enzymes play distinct roles in lipid remodeling and root hair growth in Arabidopsis under phosphate deficiency, influencing root hair density and length in a tissue- and time-specific manner.

Researchers developed a method to detect hormone-blocking drugs in wastewater and found them in Beijing's sewage, suggesting they can survive sewage treatment.

This review summarizes that polyesters hold promise for vascular tissue engineering due to their mechanical properties and biodegradability, but optimizing their use in repairing damaged blood vessels remains challenging due to the complexity of vascular tissues.

This article reviews the potential risks of various phytotoxins in milk for animals and humans, discussing the need for awareness and further research but providing no new findings.

This study demonstrated that hair relaxers containing common chemicals significantly reduced cell viability and increased apoptosis in human skin cells, suggesting potential toxicity that could be assessed with advanced in vitro technologies rather than animal testing.

This study suggests that low phosphorus and ethylene may influence root hair density through separate pathways, with ethylene manipulation affecting root hair growth in Arabidopsis thaliana.

This study found that low doses of bisphenol A may increase proliferation of the ventral prostate in adult rats by altering the estrogen to androgen ratio and gene expression.

This study found that the majority of "hypoallergenic" hair dyes still triggered allergic reactions in patients sensitive to para-phenylenediamine.

This review discusses the pathophysiologic role of lysophosphatidic acid in the skin and reports no clinical results, suggesting pharmacological inhibition as a potential treatment for various skin disorders.

This letter to the editor describes a case of anagen effluvium due to thallium poisoning from Chinese herbal medicine and rodenticide but reports no new research findings.

This study found that Pseudomonas DL7 completely degraded 600 mg/L of Sunset Yellow FCF in 48 hours at pH 9, indicating potential for biomineralization of this dye.

This study developed a method using UHPLC-MS/MS and MSPE to detect trace amounts of sex hormones in cosmetics, finding progestins and estrogens in some products, and performed a preliminary safety evaluation for residual progesterone in hair loss prevention cosmetics.

This study found that incorporating steroid hormones into DPPC liposomes altered their physicochemical properties, including size, zeta potential, and phase transition temperatures.

This narrative review found that fragrances and isothiazolinone preservatives in deodorants are key contributors to skin sensitization, while magnesium hydroxide shows promise as a less irritating alternative for managing body odor without blocking sweat ducts.

This study investigated the safety and effectiveness of two thioglycolate chemical depilatory creams for full genital hair removal in men and women, finding acceptable dermal tolerance despite some instances of irritation, supporting their use for pubic hair grooming.
