This review examines testosterone's role in male health and aging but reports no new clinical results; the authors highlight the need for further research on optimal testosterone levels to prevent age-related conditions.

This study explored the complex roles of niche cells in regulating hair follicle stem cells, identifying specific cell functions such as signaling, sensing, and relaying messages, which could provide insights into treating hair loss conditions like androgenetic alopecia and alopecia areata.

Oestrogen and thyrotropin-releasing hormone affect prolactin and its receptor in human skin and hair, suggesting new treatment options for related conditions.

This review suggests that paradoxical hair growth after light-based treatments is unlikely due to the devices themselves; instead, it may be linked to other factors such as inflammation in individuals with certain conditions.

This study found that rice bran oil extracted by supercritical CO2 can be considered non-genotoxic based on in vitro and in vivo test results, despite some chromosomal aberrations observed under specific conditions.

This study found that in men with androgenetic alopecia, elevated triglycerides were the only factor consistently associated with the condition, suggesting a potential link between AGA and lipid metabolism, although other hormonal, metabolic, and sleep factors were not significantly different after propensity score matching.

This study discusses how different modes of regulated cell death in keratinocytes affect skin stem cell niches, and their role in skin inflammation, injury repair, and cancer, based on findings from human dermatological conditions and experimental mouse models.

This study observed that exposure to different wavelengths of light affects opsin and clock gene responses in skin cells, suggesting potential therapeutic approaches using photobiomodulation for dermatological conditions like psoriasis and wound healing.

This study identified m6A-related genes, particularly IGF2BP3, as significantly up-regulated in keloid patients, potentially implicating them in the condition's molecular mechanisms and suggesting targets for therapy.

This article discusses the potential benefits of GcMAF and oral MAF, developed by "Saisei Mirai", for cancer and other conditions, but reports no new clinical results.

Proteins like aPKC and PDGF-AA, substances like adenosine and ATP, and adipose-derived stem cells all play important roles in hair growth and health, and could potentially be used to treat hair loss and skin conditions.

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 analyzed skin from 538 knockout mouse mutants and identified 50 with epidermal phenotypes, providing valuable insights into genetic conditions and systemic effects related to skin abnormalities.

In this study, researchers found that stress likely triggers symmetrical alopecia in Formosan macaques in Mt. Longevity, Taiwan, with higher stress hormone levels associated with the condition.

This perspective reviews current knowledge about cellular and molecular mechanisms in wound healing from 2023–2025, highlighting inadequately understood pathways associated with conditions like keloids and chronic wounds, and discusses proposed novel therapies for these conditions.

This study demonstrated that EdnrB signaling promotes melanocyte stem cell proliferation and differentiation, enhancing hair and epidermal melanocyte regeneration, especially under conditions of active Wnt signaling.

This review examines the long-standing use of "Dictamnus" in traditional medicine, highlighting the promising potential of D. albus and D. hispanicus as herbal drug candidates, but presents no new experimental findings.

In this study, researchers created a core-shell nanozyme, CeO2@ZIF-8/Au, which autonomously regulates ROS levels to efficiently eliminate bacteria, reduce inflammation, and promote wound healing by balancing ROS generation and scavenging in response to environmental conditions.

This review explores the potential roles of extracellular vesicles in various medical fields, emphasizing their promise but noting the need for standardization and clinical testing before widespread application.

This study explored the effects of oxytocin on hair growth and found that it upregulated growth-promoting factors in dermal papilla cells and hair follicle organoids, suggesting potential for developing new alopecia treatments.

This study found that androgen receptor signaling is linked to blood vessel regression in the dermal papilla of balding scalp, contributing to hair follicle miniaturization in androgenetic alopecia.

This study observed that dandruff-affected scalp skin has increased T-cell infiltration in the epidermis and a reduction in the hair follicle's physiological immune privilege, particularly in the suprabulbar outer root sheath area, indicating a distinct immune microenvironment compared to healthy scalp.

This study reviewed various methods and techniques aimed at overcoming limitations in culturing human hair follicles, specifically focusing on restoring the inductivity of hair follicle cells for successful hair regeneration.

This study found that cultured hair follicle dermal cells support maintenance and potentially aid in the clinical application of pluripotent and haematopoietic stem cells.

This study used single-cell RNA sequencing to analyze 26,573 cells from the scapular skin of yaks, identifying 11 major cell types and providing insights into the diversity and morphogenesis of hair follicle cell types through detailed maps of DP cells and dermal fibroblasts.

This review reports no new results but highlights the secretory function of keratinocytes, focusing on how various secretions, notably growth factors, impact stem cell differentiation into keratinocytes.

This study found that silibinin may promote hair growth by increasing proliferation and activating the AKT and Wnt/β-catenin signaling pathways in 3D cultured human dermal papilla spheroids.

This study demonstrates the use of microscopy-guided laser ablation to create a highly structured 3D hydrogel-based organotypic skin model with folliculoid structures, potentially useful for studying hair follicle development or bioactive substance screening.

The researchers reported that PPARβ/δ may influence the yak hair follicle cycle by modulating lipid metabolism in dermal papilla cells, with varying expression during different hair growth phases, affecting both lipid content and cell proliferation.

In this study, cinnamic acid was found to enhance hair growth in human dermal papilla cells and hair follicle organoids by activating oxytocin signaling, suggesting its potential for developing hair growth-promoting products.
