This article reviews the biological and physical principles of laser hair removal and reports that current laser systems do not consistently achieve permanent hair follicle destruction across treated areas.

This study estimates that young adults have about 230,000 tactile afferent fibers innervating their skin, with density varying by region and decreasing with age.

This study reviews the evolution and modifications of microneedle drug delivery systems, initially designed for percutaneous use, now expanded for targeting a variety of tissues and organs such as ocular, oral mucosal, and gastrointestinal, suggesting widespread future applicability.

This review discusses the mechanisms associated with protoporphyrin IX in living cells and reports no clinical results; the authors emphasize its potential in cancer diagnosis and the risks of toxicity.

This study found that matriptase, a membrane serine protease, is crucial for maintaining multiple types of epithelial tissues in mice, with its absence leading to severe organ dysfunction and increased permeability.

This review discusses the roles of TGF-β family signaling in regulating normal and cancer stem cells and highlights the need for further research to develop potential cancer treatments; it reports no new results.

In this study, researchers found that bulge cells in mouse hair follicles undergo transient proliferation during early anagen, indicating their role as follicular stem cells. However, another factor beyond dermal papilla proximity may be required to initiate a new anagen phase.

This research found that liquid-state liposomes and niosomes may enhance finasteride delivery to pilosebaceous units in hamsters more effectively than gel-state vesicles or hydroalcoholic solution.

This article reviews the classification of hair shaft abnormalities, outlining their diagnostic features, but does not present new research findings.

This review discusses the historical development, mechanisms of action, and potential new clinical applications of the drug cepharanthine, highlighting its multi-faceted pharmacological properties; it reports no new clinical results.

This review covers recent findings on stem cell plasticity under normal and cancerous conditions but presents no new experimental results, highlighting implications for regenerative medicine and cancer treatments.

This review discusses the functions and potential therapeutic targeting of TRP ion channels in the skin, noting their involvement in both physiological processes and various pathological conditions, but reports no new experimental results.

This study found that applying dexamethasone to mice induced catagen-like follicle changes significantly earlier and more consistently than a vehicle, such changes being useful for studying hair follicle regression.

This study observed that patients receiving IL-2 immunotherapy developed a skin eruption characterized by burning and pruritus, which resolved shortly after stopping the infusion, suggesting that IL-2 mediated these effects.

This study found that expressing certain PIN proteins in Arabidopsis root hairs inhibited growth by decreasing auxin levels, while PIN5 slightly stimulated growth, demonstrating differential effects on auxin transport.

In this study, the researchers established a dose–response relationship between the hair follicle dose during cranial irradiation and the development of permanent alopecia, with other factors showing limited correlation.

This review discusses the pharmacological properties and therapeutic potential of K+ channel opening compounds, noting their prospective use in treating cardiovascular and respiratory conditions, but reports no new results.

This essay discusses the establishment, maintenance, and role of skin stem cells in tissue homeostasis, wound repair, and their relation to skin cancer, without reporting new experimental findings.

This review discusses the developments over the past five years in nanozyme-based theranostics for tumor therapy, including their classification, design, and synergistic strategies. It also outlines the challenges and prospects of using nanozymes to enhance selectivity, biosafety, repeatability, and stability in therapeutic applications.

This study found that postnatal treatment with recombinant EDA normalized adult teeth, improved sweating, and restored normal lacrimation in dogs with XLHED, suggesting its potential as a treatment for the condition.

This study suggests that nerve growth factor plays a crucial role in the stress-induced termination of hair growth in mice, and its antagonism might offer a therapeutic approach to mitigate stress-related hair loss.

This review discusses advanced techniques for investigating stem cell fate at the single-cell level, including lineage tracing, time-lapse imaging, and molecular profiling, but reports no new research results.

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 the applications and research on fibroblast growth factors, including their use in wound healing, diabetes, and cancer, but it reports no new clinical results.

In this mouse study, severe selenoprotein deficiency in epidermal cells was linked to skin abnormalities, disrupted hair follicle development, and progressive alopecia, highlighting the role of selenoproteins in skin and hair health.

This review discusses neural mechanisms involved in hair growth control, focusing on piloneural interactions, but reports no clinical findings; the authors suggest further exploration for managing hair growth disorders.

This review discusses the use of very low-calorie ketogenic diets for obesity management and provides recommendations for nutrition experts, but reports no new clinical results.

This article reviews the diagnostic criteria and prevalence of PCOS, emphasizing its status as the most common endocrine disorder among women of reproductive age, with no new clinical results reported.

This guideline review discusses current symptoms, diagnostic approaches, and treatments for Long- and Post-COVID, based on today's knowledge, and emphasizes its practical application with ongoing updates as new insights emerge.

This study found that the transcription factor p63 is crucial for horizontal basal cell differentiation in the olfactory epithelium, suggesting a p63-dependent mechanism activates reserve stem cells after injury.
