This study by Gerald Combs suggests that selenium may help prevent cancer, but both deficiency and excess can lead to serious health problems.

This study found no significant differences in selenium levels in blood or hair between healthy individuals from high and low nasopharyngeal carcinoma risk areas, suggesting selenium levels are not influenced by age, sex, or residence.

This study determined the levels of several elements including iodine and bromine in hair samples from patients with various thyroid diseases compared to control groups without such conditions.

This study found that theabrownin-selenium nanoparticles (TB-Se NPs) effectively target Malassezia-induced dermatitis through a dual antifungal and immunomodulatory mechanism, suppressing fungal overgrowth, reducing inflammation, and enhancing immune memory to prevent recurrence in a dermatitis model.

In this case study, a 9-year-old boy with progressive scalp alopecia was diagnosed with tinea versicolor caused by Malassezia, and treatment with topical ketoconazole and selenium sulfide resulted in full hair regrowth in 6 weeks.

This study found that combining multiple low-dose exosome injections with NIR-II-responsive selenium telluride-mediated photothermal therapy significantly improved healing in diabetic mice with pressure ulcers, enhancing wound closure, hair follicle regeneration, and collagen remodeling compared to single high-dose exosome treatment.

This study found that a shampoo containing 1% selenium sulfide and 1% salicylic acid significantly improved the clinical signs and symptoms of seborrheic dermatitis and dandruff over an 8-week period.

This study developed a novel hydrogel combining Chlorella extracellular polysaccharide–selenium nanoparticles (EPS-SeNPs) with biocompatible components, which demonstrated strong antibacterial and anti-inflammatory effects, significantly accelerating wound healing in an infected rat model, and enabling pH-based monitoring of healing.

This abstract introduces dandruff as a key obstacle to achieving beautiful hair and a healthy scalp, noting its impact on appearance and self-confidence, but it does not provide study results.

This article reviews the causes, characteristics, and treatment options for seborrheic dermatitis, discussing its prevalence in specific populations, without providing new research findings.

This chapter reviews factors affecting hair growth and shedding and describes various conditions that can lead to hair growth diseases, but it reports no new clinical findings.

This case report describes a male Persian cat with Cheyletiella spp. infestation causing alopecia and pruritus, which was successfully treated using ivermectin and selenium sulphide shampoo.

This study describes cases of diffuse alopecia and thyroid alterations in sheep, linking selenium and zinc deficiencies to decreased serum T3 and T4 concentrations and related skin conditions.

This study evaluates the effectiveness of medicated shampoo against hair loss using a questionnaire distributed to 100 people, but it reports no new clinical results.

This paper reviews the diagnosis and treatment of inflammatory tinea capitis, highlighting the importance of laboratory confirmation and recommending griseofulvin as the gold standard treatment.

This case report describes a 15-month-old girl with a history of dermatitis, eosinophilic esophagitis, and failure to thrive, leading to a suspected diagnosis of Netherton syndrome.

This report warns that the Total Body Mega Formula nutritional supplement may cause selenium toxicity leading to significant hair loss.

This article discusses the formulation and evaluation of hair gels that may improve the treatment and prevention of dandruff by providing longer-lasting effects compared to traditional shampoos and lotions, but it reports no new clinical findings.

In this study, buffalo calves fed only corn silage showed deficiencies in copper, zinc, selenium, and vitamin A, along with improved physiological conditions after dietary supplementation and treatment.

This study identified specific genes that are more abundantly expressed in black hair than in gray hair, with black hair displaying higher expression of pigment-related proteins and gray hair showing increased expression of keratin-related genes.

Hair loss in children can be caused by fungal infections, trauma, autoimmune disorders, or stress, and treatments vary depending on the cause.

In this study, personalized treatment of folic acid and vitamin E deficiencies improved hair parameters in AGA patients, while Se supplementation might be unnecessary.

In this study, researchers developed a novel 3D bio-printed skin scaffold using exosomes from liver cells, which enhanced wound healing by promoting cell growth, angiogenesis, and reducing inflammation in large skin injuries, suggesting potential applications in treating chronic skin conditions.

This review explores prostate cancer risk factors, screening, treatment, and potential roles of selenium and 5-alpha reductase inhibitors in risk reduction but presents no new clinical data.

This review found insufficient evidence to conclude that selenium supplementation is effective for treating Hashimoto's thyroiditis, highlighting the need for more high-quality randomized controlled trials.

This study found that patients with age-related cataracts had significantly lower levels of manganese, selenium, vanadium, and zinc in their serum compared to healthy controls, with low serum selenium and zinc levels showing an independent association with an increased risk of cataracts.

This study reported that high cholesterol levels were linked to increased prostate cancer risk, while selenium supplementation affected gene expression, suggesting nutritional and clinical factors might influence prostate cancer risk and biology.

This review examines the current research on chemopreventive agents for prostate cancer, highlighting that while no definitive strategies have been confirmed, substances like finasteride, selenium, and vitamin E show promise in reducing risk.

This review discusses various prostate cancer prevention strategies and reports no new clinical results; the authors highlight the need for ongoing research in this area.

This narrative review highlights the crucial role of micronutrients and gut microbiota in thyroid function and suggests that nutritional imbalances may contribute to thyroid dysfunction or diseases.
