In this study, high selenium diets from different sources caused weight and hair loss in pigs, with additional hoof and coronary band problems particularly in those fed sodium selenate.
research Decreased selenium intake and low plasma selenium concentrations leading to clinical symptoms in a child with propionic acidaemia
This case report observed that a selenium-deficient diet in a child with propionic acidaemia led to macrocytosis and hair abnormalities, which improved with selenium supplementation.
research Antioxidant and prebiotic activities of selenium-containing green tea
This article reviews the role of prebiotics and the potential of green tea and selenium as alternatives due to their non-toxic nature, but it reports no new research findings.
research Effect of selenium sulfide suspension on hair roots.
This study investigated the effects of selenium sulfide suspension on hair roots after noticing higher abnormal hair root proportions in individuals using the preparation.
research Improved fetal hair follicle development by maternal supplement of selenium at nano size (Nano-Se)
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.
research Selenium and Polycystic Ovary Syndrome; Current Knowledge and Future Directions: A Systematic Review
This systematic review found insufficient evidence to support protective effects of selenium on polycystic ovary syndrome complications, despite some studies suggesting it may reduce insulin resistance and dyslipidemia.
research Primary hair growth in dogs depends on dietary selenium concentrations*
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.
research Soil, grain and water chemistry and human selenium imbalances in Enshi district, Hubei Province, China
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.
research Selenium levels in new growth hair and in whole blood during ingestion of a selenium supplement for six weeks
Selenium increased in hair but not in blood after taking supplements.
research Green hair discoloration due to selenium sulfide
In this case report, the authors describe green hair discoloration in a patient attributed to the use of selenium sulfide.
research Incorporation of Selenium-75 into Dog Hair

research Selenium Disulfide Shampoo
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.
research Biomarkers of selenium status in dogs
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.
research Investigation of Selenium Sources Associated with Chronic Selenosis in Horses of Western Iowa
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.
research Alterations in transcriptome and antioxidant activity of naturally aged mice exposed to selenium-rich rice
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.
research Selenium status in Sudanese children with protein-calorie malnutrition.
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.
