This study found that maternal Nano-Se supplementation in cashmere goats improved antioxidant status and promoted secondary hair follicle development in fetuses at 110 days.

This study found that both low and high dietary selenium levels reduced hair growth in adult dogs, with optimal growth observed at mid-range selenium concentrations.

This review discusses selenium's role in human and animal health, its deficiency's link to diseases in China, and the need for precise geochemical control data; it reports no new findings.

In this case report, the authors describe green hair discoloration in a patient attributed to the use of selenium sulfide.

Selenium increased in hair but not in blood after taking supplements.

This study found that small amounts of subcutaneously injected Se75 were deposited and retained in the hair of dogs for up to 316 days.

This study identified dose levels of selenium that can produce toxicity, noting that doses as low as 2-3 µg Se/kg bw/day can lead to adverse effects, and a human mortality study linked 300 µg/day consumption to increased death risk.

This study found that neither a single application nor prolonged exposure to selenium sulfide had a significant effect on hair growth or rest phase percentages.

This study found that urinary selenium to creatinine ratio and serum selenium concentrations quickly respond to changes in dietary selenium, making them useful biomarkers for assessing selenium status in dogs.

This study identified chronic selenosis in horses in western Iowa due to elevated selenium intake from locally produced alfalfa hay, leading to symptoms like alopecia and hoof deformities.

In this study, selenium-rich diets enhanced antioxidant activity in aged mice, suggesting potential biological benefits, although further trials are needed to fully understand long-term risks and benefits.

This study observed that selenium levels were lower in Sudanese children with malnutrition compared to healthy German children, with a good correlation between selenium and glutathione peroxidase activity.

Using Selenium Disulfide shampoo weekly helps prevent scalp dermatitis flare-ups.

This review discusses the forms of selenium and sulfur in soil, their plant absorption, and risks of toxicity to livestock, emphasizing selenium's role in selenosis and sulfur's link to polioencephalomalacia in ruminants; it reports no new experimental results.

This study found that an imbalance of selenium in a C57BL/6 mouse model led to hair loss with color change and was linked with changes in hair follicle apoptosis markers.

This study found that boys in Mexico City with selenium intake below the recommended dietary allowance had lower odds of progressing to advanced stages of pubertal development, while no association was observed in girls.

This report describes a case of acquired yellow hair discoloration in a 77-year-old woman, potentially caused by applying selenium sulfide after bacitracin zinc to her scalp.

This study found that growth affects selenium deposition in hair, nails, and other tissues of adult and weanling rats, indicating dietary and physiological factors may influence selenium levels.

This study found that both hard and soft selenium disulphide-based detergents significantly increased triglyceride levels in human hair, suggesting enhanced sebum production with reduced lipolytic activity, but showed no significant differences between their effects.

This study found that rabbits fed a diet deficient in Vitamin E developed severe muscular dystrophy that was not fully prevented by adding selenium, Vitamin E supplements, or natural feedstuffs, indicating other nutritional deficiencies.

This review discusses the potential link between selenium supplementation and symptoms of chronic selenium toxicity, such as hair loss and nail dystrophy, due to excess intake leading to disruptions in hair and nail protein structure.

This study found that puppies fed organic selenium had better retention of selenium compared to those fed inorganic selenium, with no significant difference in coat quality or hair growth.

This study found that one month of selenium supplementation improved liver and kidney function biomarkers and reduced severe hair loss in patients with beta-thalassemia major.

This documentation reviews the absorption, metabolism, and excretion of selenium and its compounds, highlighting the complex interactions and health implications, but reports no new clinical results.

This study found no significant difference in serum levels of lead and selenium between patients with premature hair graying and those without it.

This review discusses the dual role of selenium in human health, highlighting both the dangers of deficiency and potential toxicity from over-supplementation, without presenting new clinical results.

This study found that an Enterobacter isolate demonstrated high resistance to selenate and effective sorption capacity, suggesting potential for bioremediation of selenium-contaminated environments.

This article discusses the dual nature of selenium, highlighting its essential metabolic roles and potential toxicity at high doses, and reports no new experimental findings.

In this case report, a 27-year-old woman experienced severe multisystem toxicity, including toxic encephalopathy, vision, and hearing loss, after ingesting selenium at occupationally high doses, suggesting such exposure can lead to previously unreported effects of vision and hearing impairment.

This review discusses the transformation of selenium nanoparticles into multifunctional platforms for skin disease treatment, focusing on engineering principles rather than their intrinsic bioactivity alone, and reports no new clinical results.
