This study found that finasteride improves scalp hair growth in men with male pattern hair loss by reducing scalp dihydrotestosterone levels, but it did not benefit postmenopausal women with female pattern hair loss.

This literature study reviews the consequences of hair loss due to chemotherapy and nursing care interventions but reports no new clinical results.

New research suggests that skin cell renewal may not require a special type of cell previously thought to be essential.

This study found that aging in the epidermis disrupts cytokine balance and stem cell function, which may contribute to broader tumor-suppressive mechanisms.

Different types of stem cells and their environments are key to skin repair and maintenance.

This review article provides an updated overview of the pharmacology, mechanism of action, clinical efficacy, and adverse events associated with topical minoxidil, a widely used treatment for androgenetic alopecia and other hair loss conditions, while noting that its exact mechanism is still not fully understood.

This review explores the biology of wool follicles and suggests their potential use as research models in modern biology, but it reports no new findings.

The authors concluded that the dermal response to epidermal Wnt/β-catenin signaling depends on distinct fibroblast lineages, with each responding to different paracrine signals such as Hedgehog and TGF-β.

This review examines the adaptive value and mechanisms of seasonal coat colour moulting in birds and mammals, highlighting the challenge of camouflage mismatch and the necessity for evolutionary adaptation under climate change.

This study found that treatment with mesenchymal stem cell extracellular vesicles enhanced hair growth in mice and stimulated dermal papilla cell activity and growth factor production in vitro.

This review outlines the diagnosis and management of folliculitis decalvans, an inflammatory scalp disorder, and highlights Staphylococcus aureus and immune response deficiencies as key factors in its development.

This study found that overexpression of Smad7 in transgenic mice led to severe alterations in multiple epithelial tissues, resulting in early death after birth.

This review describes recent advances in using nanoparticles for drug delivery to hair follicles, with potential applications in treating skin diseases such as alopecia and acne, but reports no new findings.

In this study of patients with Androgenic Alopecia, micro-grafts containing HD-AFSCs resulted in significantly improved hair density and follicle count over 11 months compared to a saline solution, suggesting a potential alternative therapy for hair regrowth.

This article discusses the roles of epidermal stem cells in maintaining skin homeostasis and highlights how deregulation in signaling pathways may lead to cancer, but it reports no new experimental results.

This article reviews advances in feather development and regeneration, including pattern formation, stem cell biology, and evolution, but presents no new experimental results.

This review discusses strategies for regenerating cutaneous nerve function in burn patients and highlights the potential role of autologous skin-derived adult stem cells in improving sensory recovery, but reports no new experimental findings.

This article reviews recent advancements in understanding skin stem cells and their roles in maintaining epidermal homeostasis and repairing wounds, without presenting new experimental findings.

This consensus document provides foundational position statements for dermatologic ultrasound but reports no clinical results; it aims to guide future evidence-based recommendations and guidelines.

This review discusses recent advances in hair follicle biology, regeneration, and tissue engineering, highlighting emerging therapeutic opportunities, and reports no new experimental results.

This study observed that eliminating positional error in hair segment analysis can improve understanding of changes in isotopic composition, aiding the identification of pathological conditions and dietary patterns.

This study found that p53 plays a crucial role in regulating apoptosis during hair follicle regression (catagen) in mice, and its absence leads to delayed progression and altered expression of apoptosis-related markers.

This review discusses current knowledge on the biological mechanisms of different types of alopecia but reports no new clinical findings; the authors highlight future research directions, especially regarding epidermal stem cells and immune pathways.

This review discusses hidradenitis suppurativa's pathogenesis, including its inflammatory nature and the role of smoking as a triggering factor, but reports no new clinical results.

This paper discusses the hypothesis that anti-acne agents may work by reducing FGFR2 signaling, and emphasizes FGFR2's potential role in acne pathogenesis, but it reports no new experimental findings.

This study found that overexpressing the BMP inhibitor Noggin in transgenic mice led to a significant loss of nontylotrich hair follicles, suggesting a critical role for BMP signaling in hair follicle morphogenesis and cycling.

This review outlines the development, applications, and challenges of microneedle-based drug delivery from 2000-2019, particularly highlighting fabrication techniques, but reports no new clinical results.

This review examines beta-catenin's role in stem cell renewal, lineage selection, and tumor formation in the epidermis and reports no new experimental findings.

This study suggests that CD8+ cytotoxic T lymphocytes play a crucial role in the development of alopecia areata, based on observations in rodent models that mimic human autoimmune disease.

This study demonstrated that hair follicle-derived cells can induce hair follicle formation in an in vitro skin organ culture system using human retroauricular skin specimens.
