This study reported that squamous cell carcinomas of the scalp can become extraordinarily aggressive, highlighting the need for early diagnosis and careful use of treatment strategies like wide excision and radiation therapy.

This study reported that squamous cell carcinomas of the scalp can be extraordinarily aggressive, potentially metastasizing and causing death, highlighting the need for early diagnosis and careful treatment approaches.

This review article highlights the potential of mesenchymal stem cells, their exosomes, and non-coding RNAs in repairing aging skin tissues due to their ability to secrete beneficial compounds, suggesting their promising role in photoaging treatment without causing immune rejection or granuloma formation.

This study identified that in mice, sweat gland development is directed by mesenchymal signals that suppress SHH-production, while in humans, this occurs through a BMP spike in embryonic development.

This review highlights the potential of cell-free therapies, particularly cell extracts, in addressing radiation-induced salivary gland damage from head and neck cancer treatment, emphasizing their practicality and safety compared to traditional therapies despite incomplete understanding of their bioactive components.

This study found that single high-dose irradiation in mice induced more severe acute skin injury and hair depigmentation, while fractional doses led to longer-term damage in the dermis and subcutis.

This study describes permanent scalp alopecia in patients receiving chemotherapy, radiation, or both, and highlights the need for further research to identify causative factors and mitigation strategies.

This study indicates that vitamin D3 administration may protect rat hair follicles from radiation-induced damage, as evidenced by maintained follicle numbers and increased Vitamin D receptor activity in treated skin.

This review explores how radiation-induced hair graying can be used as a model to study the mechanisms behind hair graying, focusing on cellular senescence and potential therapeutic targets to address age-related changes. Results are not provided.

This study observed that while X-ray radiation did not alter major hair keratin composition in mice, it decreased hair follicle stem cell markers and increased Krt5, suggesting potential as a radiation biomarker.

This study found that far-infrared radiation preconditioning significantly enhanced the proliferation, survival, and migration of bone marrow-derived stem cells in vitro, indicating potential therapeutic benefits for cardiac ischemia treatment.

This study established a rat model of radiation-induced dermatitis using 90 Gy irradiation, which may aid in exploring new treatments and understanding the pathology, particularly highlighting autophagy regulation as a potential therapeutic target.

This review discusses the protective and stress-buffering roles of melatonin in skin functions and structures but does not present new clinical findings.

This review discusses the role of the circadian clock in skin functions such as cell proliferation and UV protection and reports no new results; the authors note its potential in studying immune regulation and seasonal behaviors.

This review examines apoptotic and anti-apoptotic mechanisms in skin homeostasis and related diseases but presents no new research findings.

This study discovered that the circadian clock influences hair follicle regeneration, making hair grow faster in the morning and causing more radiation-induced hair loss in the morning compared to the evening.

This study reports that adipose-derived stem cells can protect against radiation-induced dermatitis in rats by reducing apoptosis through lowering Cathepsin F expression, suggesting a potential new therapeutic approach.

This review discusses the potential dermatological applications of Dendrobium officinale polysaccharides, noting their hair growth promoting, skin moisturizing, and antioxidant effects, but reports no new clinical results.

This review addresses the role of skin-resident adult stem/progenitor cells in skin homeostasis, disease, and cancer development, and reports no new research results.

This article reviews the cutaneous reactions and characteristic skin changes associated with chemotherapy, radiation therapy, and new targeted cancer treatments, reporting no new clinical results.

This study found that melatonin, when administered to Wistar rats prior to and after radiation exposure, reduced oxidative stress markers and histopathological damage in skin tissue compared to radiation alone, suggesting it may effectively prevent and treat radiation-induced skin injury.

In this case report, estrogen substitution therapy slightly increased hair volume in a 22-year-old patient with genetic predisposition to hair loss and alopecia caused by past treatment for leukemia, but hair loss returned after stopping the therapy.

This article discusses the factors influencing anticancer therapeutic regimens and reviews mechanisms of action and side effects of major chemotherapeutic agents without reporting new research findings.

Skin aging reflects overall body aging and can indicate internal health conditions.

Hair health is influenced by genetics, aging, and environmental factors, with proper care needed to maintain it.

This review outlines the various fibroblast subsets in the skin dermis, their origins, and their influence on epidermal stem cell behavior, highlighting the role of the local dermal niche in stem cell plasticity.

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.

This study found that anagen hair follicles can quickly regenerate after radiation damage by forming new progenitor cells outside the bulge, bypassing the need for telogen entry.

This study observed that topically applied RTA 408 reduced the severity of radiation-induced dermatitis in mice, with the highest dose significantly reducing and alleviating skin damage and associated inflammation.

This study found that red ginseng oil promoted hair growth and protected against UVC-induced skin damage in mouse models.
