This review summarizes existing studies on toxic agents that can cause alopecia, with thallium and colchicine having the most established links, while others like botulinum toxin A need further investigation.

This meta-analysis suggests that patients with alopecia areata have lower serum levels of zinc and selenium compared to healthy controls, which may be important risk factors for the condition.

This study found that a significant number of boreal woodland caribou in NE British Columbia showed symptoms of trace mineral deficiencies and exposure to various pathogens, with substantial winter tick infestations affecting a majority of individuals.

This piece explains that 90% to 95% of pediatric alopecia cases are due to four main causes: alopecia areata, telogen effluvium, tinea capitis, and trichotillomania, with diagnosis typically confirmed through careful examination.

This study found that both ketoconazole 2% shampoo and selenium sulphide are effective for dandruff treatment, but ketoconazole also reduces hair growth.

This consensus paper reviews expert opinions on treating telogen effluvium but reports no new clinical findings.

This article reviews inherited mineral and trace element disturbances and reports no clinical results; it highlights conditions like hypomagnesaemia and acrodermatitis enteropathica linked to impaired nutrient absorption.

This study observed that daily selenium sulfide shampoos successfully removed fungal spores hidden beneath the hair cuticle in patients infected with ectothrix Microsporum canis.

In this study, women with severe hair loss after bariatric surgery had lower zinc intake compared to those with mild hair loss, suggesting a possible link between zinc consumption and hair loss severity.

This study found that a hair serum containing amla extract, freeze-dried coconut water, and selenium significantly improved hair growth rate, density, and reduced hair fall among healthy volunteers over 90 days.

This report describes a case of acute telogen effluvium in a 38-year-old woman following recovery from COVID-19.

This study reports a case where excessive consumption of "paradise nuts" led to acute selenium toxicity and massive hair loss.

This article discusses temporal triangular alopecia, emphasizing the need for increased awareness to prevent misdiagnosis and ineffective treatment, but reports no new clinical results.

This review of studies on prostate cancer chemoprevention in Europe reports no robust evidence supporting the effectiveness of chemopreventive agents, though vitamin E and selenium may potentially contribute to prevention efforts.

This case study reports that selenium shampoo, bacterial infection with trichomycosis axillaris, and possibly strongyloides larvae may have contributed to acquired hair shaft abnormalities resembling trichorrhexis nodosa in two patients.

This case report describes a 4-year-old girl in Singapore with inflammatory tinea capitis, which improved with oral griseofulvin and selenium sulfide shampoo.

This study found that serum levels of zinc, copper, and selenium were significantly lower in patients with alopecia areata compared to healthy controls, regardless of the number of hair loss patches.

This review discusses the use of nutraceuticals in dermatology for preventing and reversing signs of skin aging, but it reports no new clinical results.
