HEV light can harm or help skin and scalp, so safe exposure guidelines are needed.

This review suggests that the gut microbiome and metabolome may play a significant role in alopecia areata and emphasizes the potential of targeting these factors for improved prevention, diagnosis, and treatment strategies for this skin condition.

In this study, Allium hookeri extract increased viability and size of dermal papilla cell spheroids and reduced oxidative stress effects, potentially promoting hair growth by regulating specific protein signaling pathways in human cells.

In this study, Agaricus bisporus derived β-Glucan particles demonstrated antimicrobial, antioxidant, and anticancer effects against cervical cancer HeLa cells, suggesting potential as a therapeutic option.

This study found that PPARα agonists provided protective effects in mouse models of alopecia areata by promoting early reversal of the condition and inhibiting T effector cell function, indicating potential therapeutic value for this inflammatory condition.

This review summarizes the biological process of melanogenesis and evaluates natural skin-whitening treatments based on their mechanisms affecting melanin production, aiming to inform on the effects and awareness of skin-bleaching creams.

This study found that essential oils boost hair growth activity in dermal papilla cells by scavenging reactive oxygen species and upregulating growth factor biomarkers.

This study found that oral probiotic supplementation over 12 weeks may improve hair growth, skin condition, metabolic health, and stress responses in Chinese adults with hair loss and a high risk of metabolic syndrome.

This review discusses the potential of using human hair proteomics for non-invasive diagnostic and forensic applications but reports no new results; the authors highlight areas needing further research.

In this study, Satura® Rosta remedy was found to significantly increase hair follicle size, hair root volume, and skin thickness in mice, potentially by prolonging the anagen phase, with notable hair regrowth observed in older mice with alopecia.

Twisting hair weakens it, but strength can be recovered at low twist levels.

This narrative review analyzed the literature on premature hair graying, identifying potential contributors such as nutrient deficiencies, oxidative and emotional stress, smoking, genetic factors, autoimmune diseases, and medication side effects, but reported no effective treatment to reverse it, underscoring the necessity for further research.

This review evaluates photobiomodulation's diverse clinical uses in sports and medicine, reporting physiological modulation and potential therapeutic benefits, but emphasizes the importance of precise dosimetry for success.

This study found that ursolic acid at 50 mg/kg improved biochemical, hormonal, and ovarian histopathological markers in a rat model of PCOS, suggesting its potential as a therapeutic option.

This review explores how various skin cell types contribute to photoaging driven by UV radiation, detailing their interactions and molecular mechanisms like oxidative stress and ECM degradation, ultimately offering insights for future anti-photoaging strategies.

This systematic review found that exosome-based therapies significantly improve skin elasticity, reduce wrinkle depth, enhance hydration, and modulate pigmentation, with minimal adverse events reported across multiple studies. However, further clinical trials are necessary to confirm long-term efficacy and safety.

This study used a zebrafish model and advanced mass spectrometry to identify 11 metabolites of epristeride, revealing significant effects on purine metabolism and aromatic amino acid biosynthesis, which may aid in developing anti-doping detection methods.

In this animal study, AGO (agomelatine) effectively alleviated testosterone-induced benign prostatic hyperplasia in rats by reducing oxidative stress and inflammation, indicating its potential as a therapeutic option for managing BPH through specific signaling pathways.

This systematic review reported that probiotics, prebiotics, synbiotics, postbiotics, and dietary supplements may improve hair density and reduce dandruff severity in individuals with scalp disorders, potentially by modifying inflammation, oxidative stress, and microbiota composition; however, variability across studies limits the strength of these conclusions.

This study found that children with alopecia areata had higher levels of oxidative stress markers but showed no significant differences in depression and suicide tendencies compared to healthy peers.

This review investigates how selenium, a trace element found in wheat, may impact hair health by examining its biochemical role in hair follicle biology and its potential therapeutic and toxicological effects.

This review highlights morphological factors contributing to age-related alopecia and suggests further research to understand and potentially mitigate cellular aging processes affecting hair quality.

Among adult male rats, this study found that combined exposure to lithium carbonate and lead acetate over 28 days led to synergistic cardiotoxic effects, evidenced by oxidative stress, ECG abnormalities, and molecular markers of increased apoptosis, despite no observable structural damage to myocardial tissue.

This study reviews current research on skin repair and regeneration, highlighting promising methods such as stem cell therapies, nanotechnology, and skin substitutes, which may enhance healing and resistance to environmental damage.

This study found that among women with PCOS, the FokI CC genotype of the VDR gene may offer protection against acne and seborrhea, while the VDR-TaqI dominant genotype is associated with reduced oxidative stress.

In this report, a unique case of premature graying in a 32-year-old male, with onset at age 15 and a distinctive fractal pattern, was presented, highlighting the need for further investigation into its potential causes and mechanisms.

This study examines the effects of excessive or prolonged exposure to blue light on retinal function and highlights its potential health implications, noting that both photoreceptor and intrinsically photosensitive retinal ganglion cells (ipRGCs) are particularly sensitive to blue wavelengths.

This study found that Glehnia littoralis and Andrographis paniculata may support hair growth by protecting against oxidative stress and increasing VEGF and Wnt/β-catenin signaling in human hair follicle dermal papilla cells, with enhanced effects when combined.

This paper reviews existing research on the cosmetic benefits of hemp-derived cannabinoids for skin and hair, highlighting their unique mechanisms of action, while discussing formulation, legal, and regulatory challenges associated with using these compounds in cosmetic products.

This research suggests that phytoestrogen-rich herbal extracts may help reduce hyperandrogenism, insulin resistance, and ovarian weight while promoting ovulation in polycystic ovarian syndrome, indicating potential for discovering new bioactive compounds.
