Micronutrient deficiencies might contribute to alopecia areata.

In this study using C57BL/6 mice, researchers found that iron oxide nanoparticles permeated skin primarily through hair follicles and sebocytes, with absorption increasing over time.

This special issue reviews advancements in engineering cell microenvironments for tissue engineering, highlighting various studies on interventions like silk fibroin and platelet-rich plasma, but presents no new empirical findings.

This study found that microspicule cosmetics with low-molecular-weight peptide complexes significantly improved skin whitening, pore condition, and skin barrier function over four weeks compared to a non-microspicule formulation.

This report suggests that correcting nutritional deficiencies may improve hair quality in patients with Monilethrix and similar hair shaft disorders, though it is not a cure.

This article discusses how nutritional and environmental factors, along with antioxidant supplementation, may improve hair growth by mitigating the effects of androgens and reports no new clinical results.

This study discusses zinc's vital role in skin cell growth and how its deficiency can lead to acrodermatitis enteropathica, marked by symptoms like alopecia and dermatitis. It notes that similar symptoms appear in people with certain metabolic conditions, referred to as acrodermatitis dysmetabolica.

This chapter discusses charnolopharmacotherapeutics for various medical conditions and suggests antioxidant-loaded nanoparticles may improve treatment by enhancing central nervous system delivery and inducing charnolophagy.

This article discusses various clinical presentations and underlying mechanisms of zinc deficiency but reports no new research findings; biochemical signs often precede clinical symptoms.

This study found no conclusive link between prolonged mibolerone treatment and perifollicular mineralization in toy poodles, suggesting it may instead be a senile change common in the breed.

This study developed a new method for detecting 30 hormones in anti-aging functional foods, demonstrating good sensitivity and reliability, and identified seven hormones in four out of 14 samples tested.

This review explores the applications of magnetized water in agriculture and medicine and notes potential benefits for human health, but it presents no new experimental findings.

This study demonstrated that an LC/MS-MS method could effectively detect and quantify the vitamin B3 vitamer nicotinamide in human hair, suggesting its potential use for long-term deficiency examination.

This study examines the role of nanotechnology in cosmetics, highlighting its benefits in improving ingredient solubility and stability, but also noting challenges such as cost, shelf life, and safety concerns, along with regulatory complexities, particularly in harmonizing global legislation.

This review summarizes recent advancements and future trends in the design and application of metal oxides for biocatalytic therapeutics, discussing their structural diversity, catalytic site tunability, and therapeutic applications, such as in cancer therapies and ROS scavenging, as well as challenges for their future utilization.

This study highlights the roles of dietary nutrients in maintaining skin health, noting that shortages can lead to hard-to-detect dysfunctions, and suggests that nutraceuticals may help address these nutritional gaps and improve skin-related issues linked to aging and dermatoses.

This study assessed iron deficiency among 135 young female military personnel, finding that 35.6% had latent iron deficiency and 34% had iron deficiency anemia, with symptoms more pronounced in those with anemia, yet iron deficiency did not significantly affect physical activity levels.

These investigations described in the study demonstrate how geochemical techniques can be applied to biological studies in Yellowstone, finding significant mercury accumulation in trout and grizzly bears which correlates with hydrothermal sources.
