This study used nanoscale secondary ion mass spectrometry to locate where calcium and copper are concentrated in colored hair, finding these metals particularly in the cuticle's sulfur-rich regions.

This study suggests that elevated copper levels in domestic tapwater, exacerbated by its aggressive properties, likely contribute to green hair by damaging the cuticle and increasing copper uptake.

This study found that lead accumulated in the hair shafts of individuals exposed to mining environments, while iron, copper, and zinc levels remained stable, highlighting the significance of SRXRF micro-analysis for environmental health research.

This study found that women experiencing hair loss post-COVID-19 showed significantly decreased serum copper levels, suggesting potential further research into copper supplementation for preventing and treating post-COVID-19 alopecia.

This study found that the Pseudomonas sp. T5-6-I strain significantly increased selenium accumulation and root hair density in Brassica oleracea, highlighting its potential for phytoremediation and biofortification.

This study reported that green tea extract may promote the excretion of copper into the hair in mice.

This study found that nanocapsules formulated as a dispersion and applied with massage may enhance follicular uptake of clobetasol propionate while minimizing its skin penetration, offering a potential improvement over conventional treatments for scalp diseases.

This study found that Wistar rats fed with grass extracts from mining areas accumulated trace metals, particularly in the spleen, leading to organ pathology and signs of toxicity.

This review examines the differences in dermatology practices between Europe and North America, noting that European dermatologists often prioritize evaluating patients' psychosocial factors and utilize nondrug treatments, unlike their North American counterparts.

This review discusses zinc's role as an essential trace element in human nutrition, particularly its importance in total parenteral nutrition, and reports no new clinical results.

This study found that higher concentrations of copper (II) ions in human hair increase protein oxidative modification, contributing to hair damage regardless of UV exposure and pigmentation level.

This review discusses the role of diet in managing hair loss during menopause and reports no new clinical results; it highlights the importance of nutrients like sulfur amino acids, vitamins, and minerals.

This article explores how various nutrients and metabolic processes impact wool and hair follicle function in animals but reports no new experimental findings.

In this study, copper was found to promote the proliferation of dermal papilla cells in Rex rabbits by maintaining the function of the cellular mitochondrial electron transport chain.

This review discusses the impact of various external factors like cosmetics, traction, and radiation on hair health and color, but reports no new findings.

This animal study found that second generation mice exposed to excess zinc during gestation and lactation had reduced plasma copper, body weight, and hematocrit, with lighter and delayed hair development compared to mice on a normal zinc diet.

This research reports that copper-quercetin complexes show strong potential in antioxidation and cancer therapy, while their effects on specific cell death pathways warrant further investigation.

In this study, the Cu-doped bioglass composite dressings showed promising results for wound healing and hair follicle regeneration in vitro, with enhanced fibroblast proliferation and vascular growth.

In this study, researchers found that most buffaloes in Basrah, Iraq, suffered mineral deficiencies, especially in zinc, cobalt, copper, and sulfur, with outdoor grazing buffaloes displaying more severe deficiencies than those kept indoors.

Nanocarriers could improve how drugs are delivered through the skin but require more research to overcome challenges and ensure safety.

This study found that scalp cooling markedly reduces cellular uptake of anthracycline drugs in human keratinocytes, partially explaining its protective effect against chemotherapy-induced cytotoxicity.

This study found that living environment significantly influenced Fe concentrations in dog and cat hair, with outdoor animals showing higher levels than those kept indoors.

This study reports a unique case of trichotillomania as a presenting sign in a patient with neurological Wilson's disease, confirmed by genetic testing and copper abnormalities.

Goat hair shows changes in metal levels and stress when goats move from indoors to mountain pastures.

This review examines nutritional deficiencies after bariatric surgery, particularly in essential minerals like zinc and copper, and highlights the need for more research to improve post-surgery nutritional outcomes.

This review discusses the genetic and biological factors influencing hair curliness, revealing strong links to specific protein variations, and reports no new clinical results.

This review discusses the mechanisms involved in wound healing and explores the potential of nanomaterials as a promising approach to managing chronic wounds, but reports no new clinical findings.

This study found that niosomes significantly enhanced the skin deposition of retinoic acid while reducing its permeation, outperforming other tested nanoformulations.

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

The researchers reported that a newly developed ionic liquid-based microemulsion significantly improved the local delivery of copper peptides in mice, enhancing hair growth-related factor activation while offering a safer, non-invasive alternative to existing treatments for hair loss.
