Hair analysis can offer clues about a person, but individual differences limit making precise identifications.

In this study, oral supplementation with NMN for 12 weeks in middle-aged Japanese women significantly increased hair growth density and diameter and improved subjective assessments of hair texture and quality of life, with no significant changes in hair hormone concentrations observed.

In this review, researchers evaluated 111 studies on the biological activities and phytochemical components of the plant Tridax procumbens, emphasizing its ethnobotanical potential and the need for more research to understand its therapeutic benefits, especially in its native tropical regions.

This study reported that a ginger-based hair tonic significantly reduced hair loss and improved hair thickness and quality over a two-week period among female participants with hair loss concerns, compared to a control group using other commercial hair loss products.

In this study, researchers observed a possible correlation between hair loss patterns and Mizaj (temperament) types, suggesting that hair loss patterns might serve as a diagnostic index for identifying individual temperaments according to the Unani system of medicine.

This study found that HOXC13 gene expression was significantly higher during the anagen phase in Angora goats, potentially contributing to the mohair's shiny and silky nature.

This review discusses the impact of chemotherapy-induced alopecia on cancer patients, the current use of scalp cooling for prevention, and potential future treatments, but presents no new clinical results.

In this study, Dheedhi Hair Care herbal shampoo significantly reduced hair fall and dandruff compared to a regular shampoo, with no reported side effects.

This study suggests that while hair analysis using GC-MS is a sensitive method for detecting cocaine ingestion, it may not reliably indicate the amount, timing, or duration of drug use due to interindividual variability and multiple incorporation mechanisms.

This study outlined modern approaches for using cosmeceuticals in trichology, emphasizing evidence-based medicine, personalized care, and patient safety. It proposed the H.A.I.R. model as a universal algorithm for trichological programs and suggested new educational and practical tools for specialists in trichology and aesthetic medicine.

In this study, 27.9% of Parkinson's disease patients reported hair loss, with a higher incidence linked to a daily levodopa-equivalent dose over 448 mg, suggesting an association between dopaminergic medication use and hair loss complaints.

This study developed a novel system that can automatically estimate hair loss parameters from images without expert input, reporting satisfactory results from testing on samples collected in Kolkata.

This chapter reviews hair anatomy, hair shaft structure, and various cosmetic treatments that can alter or damage hair, but it presents no new research findings.

This report describes a study of estuarine bed-sediment quality in New Jersey and New York post-Hurricane Sandy, focusing on contamination extent and potential long-term impacts, with no new findings included.

This study found that lower serum melatonin levels were associated with increased skin aging grades among individuals in Ulaanbaatar, suggesting melatonin loss may contribute to earlier skin aging.

This study found that microplastics on the Lebanese Mediterranean coast transport various organic and inorganic pollutants, posing threats to marine organisms and potentially human health.

This chapter reviews the potential of adipose-derived stem cells for skin aging and hair loss treatments but reports no new experimental results; the authors highlight these stem cells as a promising regenerative resource.

This study found that a genetic variant in the EDAR gene leads to typical East Asian hair characteristics by increasing signaling output, as shown in transgenic mice experiments.

This review provides an overview of current research on AD-MSCs, PRP, and biomaterials, highlighting their safety and efficacy in treating soft tissue defects and chronic wounds without major side effects.

This study found that conditioned media from epidermal progenitor cells improved skin aging signs in a clinical trial and protected fibroblasts from oxidative stress in vitro.

This review discusses the potential applications of injectable platelet‐rich fibrin in various conditions and reports no new clinical results; the authors highlight its favorable use in comparison to existing treatments.

This review summarizes the positive clinical response of using platelet-rich plasma as an adjuvant in skin rejuvenation treatments, with no identifiable complications, suggesting a promising outlook for its future use.

This review found that among emerging technologies for skin anti-aging, stem cell therapies using recipient chimerism might be more beneficial than CRISPR-Cas9 and other current innovations, though further studies on safety and efficacy are needed.

This review discusses the therapeutic properties of polydeoxyribonucleotides derived from marine organisms for wound healing and inflammation, but it reports no new clinical results.
