This review discusses guidelines for androgen use in women and concludes that more research is needed before recommending testosterone due to insufficient evidence on safety and efficacy.

This review discusses the role of lncRNA Xist in cell growth regulation and disease development, particularly cancer, and reports no new experimental results.

This article discusses the factors involved in optimizing laser hair removal, emphasizing patient selection, laser safety, and understanding laser–tissue interactions, but presents no new clinical findings.

In this study, miR-31 was found to play a significant role in hair cycle regulation in mice by controlling key gene expressions involved in hair growth and differentiation.

This review explores recent findings on regulatory T cells, focusing on their unique functions in non-lymphoid tissues and new mechanisms of action, but presents no original clinical results.

This study found that overexpression of the enzyme spermidine/spermine N1-acetyltransferase in mice was associated with increased fat oxidation and a leaner phenotype, while knock-out mice exhibited increased fat accumulation.

Scientists turned rat thymus cells into stem cells that can help repair skin and hair.

This review discusses various adverse drug reactions affecting the skin, hair, and nails, emphasizing the importance of recognizing and reporting these reactions but reports no new clinical findings.

This summary explains the different types of wrinkles, their causes, and their distinct microanatomical characteristics, noting that each type may respond differently to treatments.

This article reviews the role of skin surface lipid in mediating environmental stressors and discusses potential therapeutic interventions, reporting no new experimental findings.

This review discusses current treatment challenges and strategies for managing psoriasis in the scalp, nails, and intertriginous areas, emphasizing the need for effective and well-tolerated long-term options, but reports no new clinical results.

This systematic review reports that "COVID toes" and other skin manifestations can be initial signs of COVID-19, and advises immunosuppressive therapy adjustments only for infected or at-risk patients.

This article reviews the care of transgender patients, encompassing diagnosis, treatment options, and challenges in health care access, but does not present new research findings; the authors emphasize the critical role of providers in addressing transgender health needs.

This study describes a case series of nine patients experiencing symptoms of selenium toxicity after consuming a liquid dietary supplement with an excess amount of selenium.

This review discusses the use of Dermal Papilla cells as in vitro models for studying hair growth modulators, emphasizing their role in aiding the development of new hair treatments, but reports no new clinical results.

This study found that the combination of MT-DADMe-ImmA and MTA selectively induced apoptosis in head and neck squamous cell carcinoma cell lines FaDu and Cal27, but not in normal fibroblasts or MTAP-deficient breast cancer cells.

Most dermatologic medications are safe during pregnancy and breastfeeding, but some should be avoided due to potential risks.

This review discusses the role of the enzyme Δ9-desaturase-1 in skin lipid regulation and whole-body energy balance in mice and reports no new experimental results.

This review discusses the current understanding of hair photodamage and photodegradation and reports no new findings; it highlights unresolved questions about radiation effects and melanin's role in different hair types.

This article discusses a proposed "Darwinian" model of carcinogenesis and emphasizes that cancer prevention involves more than avoiding mutagens, as gene-environment interactions are complex and non-linear.

This review discusses the multiple layers of environmental controls on hair stem cell homeostasis and suggests that targeting these layers could offer safer regenerative medicine therapies without directly using stem cells.

This review presents updated tables of mouse mutants with hair growth abnormalities to aid in understanding the molecular mechanisms of human hair disorders, but reports no new clinical results.

This study observed that hair loss in captive rhesus macaques varies with season, sex, and housing conditions, and is significantly correlated with HPA axis activity as indicated by faecal cortisol metabolites.

This study demonstrated that metabolomics could identify persistent biomarkers distinguishing between heavy ion and γ radiation exposures, offering a potential tool for assessing long-term radiation risk for intestinal pathologies.

This article discusses the history and terminology of toxic epidermal necrolysis but reports no new clinical results.

This article discusses how drug molecules integrate into hair fibers, focusing on biological transport mechanisms and physicochemical factors, but reports no new experimental findings.

In this study, researchers found that changes in the extracellular matrix components, particularly fibronectin, laminin, and type IV collagen, during the rat vibrissa follicle growth cycle, suggest dynamic remodeling related to dermal-epidermal signaling.

This review discusses the paracrine function of mesenchymal stem cells in tissue regeneration and repair, focusing on secreted bioactive substances and their role under different microenvironments; it reports no new clinical results.

This review discusses the biological effects and mechanisms of THSG in antiaging and related disease treatments but reports no new experimental findings.

This study found that children with alopecia areata experienced more stressful life events and excreted higher levels of catecholamines compared to healthy siblings.
