This study highlights multiple factors contributing to hair graying, such as oxidative damage, melanocyte changes, and genetic influences, and suggests that repigmentation may be temporarily reversible, offering potential targets for future treatments while urging caution when applying mouse model findings to humans.

This source provides medical information intended solely for licensed professionals and emphasizes that it is not a substitute for medical advice, diagnosis, or treatment decisions, which remain the responsibility of treating physicians.

This review critically examines the current medical management strategies for BPH/LUTS and reports no new experimental results.

Knowing detailed head and neck anatomy is crucial for safe and effective facelift surgery.

This study found that ATM protein plays a crucial role in protecting human hair follicle melanocytes from oxidative stress, which is linked to the greying of hair.

This article reviews the potential of combining antiandrogenic and antiestrogenic treatments for BPH, highlighting aromatase inhibitors, but presents no new clinical results; further research is needed.

This study found that centrosome ablation in developing epidermis triggers cell surveillance pathways, resulting in thinner skin and halted hair follicle growth, while later stages of epidermal growth may operate independently of basal progenitor division orientation.

In this study, after long-term observation of human scalp hair follicles over 16 years, the researchers found that a topical 5% minoxidil solution could stimulate hair regrowth after a period of dormancy, though with reduced growth rates and hair diameter.

This review discusses the implications of deterministic chaos in pathology, emphasizing its potential impact on predicting biological behavior of lesions, and reports no new experimental results.

This review summarizes the ophthalmic complications of common periocular aesthetic treatments but reports no new clinical findings, emphasizing the importance of recognizing potential side effects.

This article reviews how the microenvironment influences adult stem cell behavior and discusses strategies to enhance stem cell function but reports no new experimental results.

This article reviews gender differences in planning and managing female cosmetic surgery patients and reports no new clinical findings.

This study demonstrated that in genetic mouse models, the calcium sensor Stim1, not Stim2, is essential for sweat secretion in sweat glands.

This review discusses stem cell behavior, highlighting their plasticity in tissue repair and the impact of somatic mutations on clonal expansion in early cancer, but reports no new experimental results.

This review discusses various stem cell compartments in adult murine and human epidermis, examining their expressed markers and characterization assays, and reports no new experimental results.

This review discusses the histopathology of male-pattern baldness and highlights ongoing disputes over several aspects, including sebaceous gland size and follicle loss, reporting no new clinical findings.

This source describes wound healing as a complex biological process that requires precise regulation and coordination among various cells, cytokines, and signaling pathways to achieve tissue repair, although specific findings or results are not provided in the abstract.

In this review, the authors propose that hair on the scalp may protect against non-melanoma skin cancer by maintaining an IL-17 biased immunosurveillance, with hair loss potentially increasing the risk of skin cancer due to disrupted immune monitoring.

This study suggests that cancer risk may be influenced by the balance of pro- and anti-oncogenic mutants in normal tissues rather than by the total number of mutations.

In this discussion, the authors highlight the murine cornea as a powerful model for stem cell research, revealing new insights into stem cell properties, differentiation flexibility, and the importance of the stem cell niche, with potential implications for understanding various tissues, diseases, and therapies.

This review provides an overview of how advancing imaging technologies, such as tissue clearing and intravital microscopy, are enhancing our understanding of tumor architecture and interactions between cancer cells and the tumor microenvironment, aiding both fundamental cancer research and the development of therapies.

This study found that a 3D wound model, the 3DWoundSE, showed improved responsiveness to injury and cytotoxic stimuli compared to an intact 3D skin equivalent, offering a reproducible and ethical alternative to animal models for early wound response assessment in dermatological research and drug development.

This study found that in stretch-mediated tissue expansion, fibroblasts adopt an embryonic-like, low-collagen state that enhances epidermal stem cell renewal, supporting coordinated skin expansion crucial for reconstructive surgeries.

This review highlights that skin organoids, advanced three-dimensional models mimicking human skin, are emerging as effective alternatives to traditional culture models and human skin, overcoming limitations of two-dimensional systems and ethical concerns, and are being increasingly used in areas like developmental biology and disease modeling.

This article reviews follicular melanogenesis, detailing how melanin synthesis and its regulation in hair follicles depend on a complex interplay of cellular and molecular mechanisms, but reports no new clinical findings.

This narrative review examines the interactions between skin stem cells and their niches, finding new insights from advancements in genetic and imaging tools but reporting no new experimental results.

In this review, the authors discuss how hair may protect against scalp skin cancer by enabling IL-17-biased immunosurveillance, while hair loss could permit tumor development by reducing this immune protection.

This article explores how societal views on "freaks" have shifted from congenital anomalies to cosmetic surgery-induced appearances, with the authors suggesting this may reflect changing beauty norms and the commodification of uniqueness.

This review examines the differential aging of melanocytes in hair follicles and skin, and reports no new findings; the authors suggest further research is needed to understand these processes.

This review discusses the effects of estrogen on skin aging and highlights potential therapies, but reports no new clinical findings.
