This study suggests that elevated levels of certain heavy metals, rather than zinc, may play a causative role in primary chronic telogen effluvium.

Children with autism have different levels of certain metals and elements in their hair and blood, affecting symptoms.

This study found that dogs with idiopathic epilepsy had altered hair concentrations of several trace elements, which may suggest a role in the disease's pathophysiology and indicate effects from antiseizure medications.

The method effectively maps lead and zinc in hair, aiding understanding of heavy metal exposure risks.

This paper reviews chemical analysis methods for trace elements in human hair and supports a no-wash policy due to challenges in distinguishing between endogenous and exogenous element sources.

This study found that a two-month antioxidant treatment significantly improved hair growth in patients with alopecia areata by enhancing antioxidant defenses and correcting trace metal imbalances.

This review found that solar radiation, pollution, and trace metals cause significant damage to human hair, with factors like UVB radiation primarily affecting light-colored and bleached hair; most data were derived from in vitro and ex vivo simulations.

This study observed that individuals with type 1 diabetes mellitus have notably lower levels of essential and trace elements like Calcium, Potassium, and Zinc in biological samples compared to non-diabetic controls.

This study found that people with chronic telogen effluvium had lower hair and serum iron levels and higher serum copper levels compared to healthy controls.

In this study, Hibiscus rosa-sinesis flower extract was found to contain 0.33% quercetin according to HPTLC analysis and 0.37% according to HPLC. Heavy metals measured were within acceptable limits, supporting the standardization of the plant material for efficacy and safety testing.

This study found that supplementing pregnant and lactating mice with high dietary copper improved survival and physical traits in mice carrying the crinkled mutation, suggesting copper's role in modulating gene expression.

This study reported a decrease in zinc and iron levels in the blood and an increase in certain trace elements in hair among patients with alopecia areata compared to healthy individuals.

This review discusses medical conditions and therapies related to various elements, such as zinc, copper, mercury, cadmium, lead, chromium, and arsenic, without reporting new experimental results; it highlights past findings on deficiencies, toxicities, and historical cases.

This review found that microneedling is generally safe, with most adverse effects being minor and resolving quickly, though there is increased risk in patients with active infections, darker skin, or metal allergies.

Gender affects hair and scalp characteristics, with differences in hormone responses, graying patterns, and trace metals.

The document concludes that the exact way alcohol causes harm to fetal development is unknown, but it significantly affects nutrient transport to the fetus and a safe level of alcohol during pregnancy is not determined.
