This study used novel methods to detect and map iodine concentrations in pig skin, finding iodine present in the coating, stratum corneum, and tissue around hair follicles.

This review discusses the clinical manifestations of malnutrition in children, particularly highlighting the overlapping skin changes from various nutrient deficiencies, and reports no new clinical results.

In this study, researchers developed a probiotic-based microneedle system combining Weissella cibaria and clascoterone to target androgenetic alopecia, which in a mouse model improved hair density, vascular regeneration, and reduced inflammation, suggesting a promising treatment approach.

This review discusses micro-segmental hair analysis for forensic toxicology, emphasizing its potential to provide detailed drug distribution profiles and its application in investigations, while noting the method's limitations and future perspectives.

The project aims to validate a nutritional intervention targeting the Redox–NO–Androgen Axis to restore mitochondrial, endothelial, and hormonal balance in male health disorders related to oxidative stress.

This study examined older adults undergoing chemotherapy and found that nutritional-inflammatory biomarker ratios were significantly linked to cognitive impairments, treatment side effects, and quality of life indicators, suggesting these lab measurements might help identify high-risk individuals for intervention.

Hair analysis may help monitor health in children with Down syndrome and obesity.

This study demonstrates that MPM-FLIM multimodal imaging can effectively assess the delivery and dissolution of zinc pyrithione particles in human skin follicles using different application techniques.

This study developed a validated method for analyzing minoxidil in hair care cosmetics, demonstrating good precision and recovery rates.

This study found that hair samples from children with kwashiorkor or marasmic kwashiorkor had about 20% less cystine compared to one child with adequate protein nutrition, suggesting the need for further research.

In this study, researchers reported that adult females approaching menopause in Canada generally had similar or lower blood concentrations of toxic, essential, and trace elements compared to their peers, but most participants showed zinc levels below the proposed adequacy threshold.

This study reports that selenium deficiency in children on long-term total parenteral nutrition may lead to symptoms like erythrocyte macrocytosis and skin and hair depigmentation, which improved with selenium supplementation.

This study found that all five toxic microelements analyzed were most prevalent in the Caspian thin-fingered gecko's bone and muscle tissues, suggesting their tolerance to these elements in polluted areas.

This research observed that while organic farming systems in Southern Norway showed decreased phosphorus over time and variable nitrogen retention, the mulching of plant material could enhance vegetable yields, suggesting a need for innovative nutrient management strategies in organic farming.

In this study, an intervention to automatically measure ferritin detected iron deficiency in about 28% of women with alopecia, potentially helping to address hair loss.

The researchers reported that the net mineral requirements for weight gain in Morada Nova lambs differ from commonly recommended values by the Agricultural and Food Research Council.

This study found that individuals with protein-calorie malnutrition, especially those with kwashiorkor, required significantly less force to pluck hair compared to well-nourished patients.

This study found that repeated oral intake of 0.5 or 5 mg/kg of cobalt ferrite nanoparticles induced pulmonary toxicity in rats, with dose-dependent oxidative stress and inflammation observed, but no notable toxicity was seen at a 0.05 mg/kg dose.

This study developed a highly sensitive fluorescent assay for measuring enzyme activity in single hair follicles, allowing the efficient analysis of over 100 samples per day.

This study found that due to variability in measurements, hair pluckability is not a reliable indicator of adult nutritional status, although it may hold potential in certain emergency situations if improved for consistency.

This study proposed a simple, rapid permanganometric method for determining minoxidil concentrations in pharmaceutical samples, offering comparable accuracy to chromatographic methods with recovery rates of 94.5 to 95.2%.

In this study, researchers determined that poor feed quality and nutritional deficiency, especially low vitamin A levels, were leading causes of impaired reproductive function in nutria, with deficiencies most pronounced during February-March and linked to clinical signs like growth retardation and alopecia.

The document concludes that hair analysis is not good for assessing nutrition but can detect long-term heavy metal exposure.

This study observed that carbon paste electrodes catalyze the electrooxidation of minoxidil more efficiently than other electrode types, with a detection limit of approximately 20 ng mL^-1.

This study validated a UV-spectrophotometric method for accurately detecting Minoxidil and Tofacitinib citrate concentrations in bulk and gel formulations for alopecia areata, showing high recovery rates and indicating the method's suitability for routine analysis.

This study reported that a biotin-rich nutrition bar stored in aluminum foil packaging showed reduced bacterial growth and remained edible for 30 days compared to other packaging materials.

Malnutrition can change hair color due to altered copper and zinc levels.

This review examines nutrient-responsive dermatoses in companion animals and reports no new results, highlighting that improved diet quality can enhance skin and hair coat health.

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 established a novel in vivo "whisker follicle microinjection assay" using mouse whiskers to evaluate hair growth and pigmentation effects of various chemicals and proteins, identifying minoxidil, ruxolitinib, and RSPO1 as growth promoters, while deoxyarbutin inhibited pigmentation and Nbl1 emerged as a growth inhibitor.
