This article reviews drug-induced hair and nail disorders and discusses their clinical recognition, underlying mechanisms, and potential treatment strategies, without presenting new research findings.

In this study, AgK114 was found to be transiently induced in hamster epidermal keratinocytes following skin damage, suggesting its role in the recovery process after injury.

This review discusses the biological and cosmetic aspects of hair aging and reports no new clinical results; it highlights current treatments and future research directions to address both aging factors.

This study found that caffeic acid reduced UVB-induced damage and oxidative stress in human dermal papilla cells, suggesting its protective efficacy against such cellular damage.

The document concludes that the skin is a complex organ providing protection, sensation, and healing, with challenges in treating conditions like itchiness.

The herbal hair serum with rosemary, hibiscus, and neem is safe and effective for hair care.

This article reviews the influence of vitamin D on various dermatological diseases and suggests that vitamin D supplementation might aid in maintaining skin cell homeostasis; it reports no new clinical results.

This study found that the 11R-No. 10 peptide, delivered transdermally, significantly inhibited melanogenesis and produced a whitening effect in a UV-induced sun-tanning guinea pig model without cytotoxicity.

This study found that certain chemotherapeutic agents, such as cyclophosphamide, disrupt feather formation and induce hair loss in mice by inhibiting cell proliferation through sonic hedgehog gene downregulation.

This article highlights the need for dermatologists to understand male-specific anatomical and physiological differences to optimize aesthetic treatment outcomes for men, but it reports no new clinical results.

This study found that a hair-coating polyphenol complex significantly enhanced the mechanical strength, UV protection, and antistatic properties of damaged hair, suggesting potential benefits for hair treatment.

This study highlights the critical role of mitochondria in skin aging and wound repair, suggesting that targeted interventions such as antioxidants, NAD⁺ boosters, and NRF2-based therapies may enhance mitochondrial function and improve cutaneous health.

This study concluded that heterozygous NFKB2 mutations lead to a distinct and severe form of primary immunodeficiency with early onset, primarily T cell-mediated autoimmunity, and impaired B-cell differentiation.

This study found that α-ketoglutarate protected dermal papilla cells from oxidative stress by enhancing the Nrf2 pathway and mitigating cell damage through the ERK/Nrf2 axis.

In a laboratory study, researchers found that a novel Bioactive Crosslink Repair Complex improved both the protection and repair of chemically damaged hair, enhancing tensile strength, shine, and cuticle alignment when added to bleaching mixtures and leave-in conditioners.

In this laboratory study, Cucumis melo var. makuwa leaf extract significantly reduced DHT-induced apoptosis in human dermal papilla cells by modulating androgen receptor activity and gene expression, suggesting potential as a therapy for androgenetic alopecia.

This study found that the combination of finasteride and black soybean extract showed synergistic protective effects against DHT-induced damage in hair follicle cells, suggesting potential benefits for treating androgenetic alopecia.

In this in vitro study, red ginseng extract and its main ginsenoside, G-Rb1, were found to protect human hair follicular keratinocytes from oxidative damage, preventing apoptosis, promoting hair growth, and modulating hair cycle transitions by influencing specific cellular signaling pathways.

This study found that sleep deprivation in mice can trigger prostatitis by activating the cGAS-STING pathway due to reduced levels of dihydrotestosterone and melatonin, resulting in a pro-inflammatory environment, while recovery sleep can mitigate these effects.

This article discusses the mechanisms behind chemotherapy-induced alopecia and the potential for permanent hair loss due to irreversible damage to hair follicle stem cells, but it reports no new clinical findings.

In this study, exosomes derived from Iris germanica L. rhizomes (Iris-exosomes) were reported to alleviate oxidative stress and improve mitochondrial function in human follicle dermal papilla cells by activating the Wnt/β-catenin signaling pathway, suggesting potential benefits for hair loss treatment.

In this study, compliance with UV protection recommendations was highest among vitiligo patients compared to those with other cutaneous immune-mediated inflammatory dermatoses, indicating a need for tailored education to improve compliance across all groups.

This review discusses recent in vitro and in vivo research suggesting that components of ginseng, such as ginsenosides and gintonin, may have potential skincare benefits, including anti-aging effects and treatment of skin conditions like atopic dermatitis and hypertrophic scars.

This study found that human umbilical cord blood-derived mesenchymal stem cells (hUCB-MSCs) significantly prevented hair loss induced by dexamethasone in a mouse model and enhanced cell proliferation in human hair follicle cells, suggesting a protective effect against stress-related hair loss.

This study suggests that hair follicle-derived mesenchymal stem cell transplantation may effectively treat acute pancreatitis by reducing inflammation and promoting pancreatic regeneration in a rat model.

This study found that KLB and EIF3C are important in the progression of vitiligo and AA, suggesting they could be biomarkers and early diagnostic targets.

In this study, researchers developed an environmentally friendly hair coating from casein proteins and tannic acid, enhancing the tensile strength of virgin Asian hair by approximately 21% compared to untreated hair, while maintaining elasticity.

Bald men should protect their scalps from the sun to reduce skin cancer risk.

This review highlights the potential of valorizing citrus by-products, particularly hesperidin from orange peels, as sustainable ingredients in skincare for antiaging, pigmentation, wound healing, and UV damage protection, emphasizing hesperidin's role in a circular economy approach.

This study found that over 26% of patients using Tripterygium wilfordii Hook F experienced adverse events, highlighting the need for better strategies to manage these risks.
