This article discusses the potential link between androgen involvement in COVID-19 pathogenesis and androgenetic alopecia, but reports no new clinical findings, highlighting a need for further research.

This study found that early-onset androgenetic alopecia, especially with a vertex pattern, may be an independent risk factor for cardiovascular disease and metabolic syndrome in men.

This study found that LED light irradiation induced proliferation and migration of human outer root sheath cells, potentially through the stimulation of the Wnt/β-catenin and ERK signaling pathways.

In this study, dermal papilla cell-derived exosomes accelerated hair follicle growth in mice, suggesting potential for treating hair loss by modulating key signaling pathways.

This study observes the expression of mRNA for androgen receptor, 5α‐reductase, and 17β‐hydroxysteroid dehydrogenase in human dermal papilla cells.

In this study, decreased expression of BMP2 and ephrin A3 and increased NT-4 gene expression were observed in dermal papilla cells from androgenic alopecia-affected skin, suggesting potential roles in hair growth regulation.

This review discusses the potential of endogenic and exogenous exosomes in dermatology and cutaneous aesthetics, highlighting their capacity to repair and rejuvenate skin tissue, but reports no new experimental results.

This review discusses various approaches to treating alopecia, including drug therapy and hair transplantation, but reports no new research findings; the authors highlight the need for novel techniques like cell culturing.

This study found that extracellular vesicles from low-passage dermal papilla cells may activate hair growth by delivering miR-140-5p, which downregulates BMP2 signaling, suggesting potential therapeutic targets for alopecia.

LED light helps hair follicle cells grow and prevents them from dying by activating certain cell pathways.

LED light helps human hair root cells grow and move by activating certain cell pathways.

LED light helps human hair root cells grow and prevents them from dying by activating specific growth pathways.

This review discusses the role of Wnt/β-catenin signaling in hair follicle regeneration and highlights recent progress in developing hair loss treatments targeting this pathway, but reports no new clinical results.

This study found that Zizyphus jujuba essential oil enhanced hair growth in mice, with the 1% and 10% concentrations showing increased hair length compared to control.

This review discusses the development of electrospun nanofibrous scaffolds for promoting angiogenesis in tissue engineering but notes that their clinical application beyond bone and skin repair is still limited.

This study found that a 70% methanol extract from red ginseng stimulated hair growth in mouse vibrissal follicles, suggesting its bioactive components, particularly certain ginsenosides, may promote hair growth.

In this study, UVB irradiation of organ-cultured human anagen hair follicles in vitro reduced hair elongation and increased cell death, affecting hair growth and regulatory processes.

This study suggests that mesenchymal stem cell-induced dermal papilla-like tissues can generate new hair follicles in mice, indicating potential for developing hair cell therapy using stem cells.

Testosterone was found to inhibit hair follicle epithelial cell proliferation in adult stumptailed macaques only when dermal papilla cells from bald scalps were present, and this effect was reversed by the antiandrogen RU 58841.

This study suggests that damaged anagen hair follicles have the capability to repair themselves and resume growth by mobilizing extra-bulge epithelial cells, particularly after injuries like chemotherapy and radiotherapy.

This study highlights that lower testosterone in men and higher testosterone in women are linked to increased risks of metabolic syndrome and type 2 diabetes, with associated skin diseases indicating potential cardiovascular complications.

This review discusses the potential of cell-derived nanovesicles as innovative treatment strategies for hair growth and provides no new clinical results; the authors emphasize the need for further understanding of their mechanisms.

This study found that FGF5-/- rabbits exhibited a significant long hair phenotype by prolonging the anagen phase, suggesting FGF5 acts as a negative regulator of hair growth.

This review discusses the potential benefits of phytochemicals for hair care and emphasizes the need for more robust preclinical and clinical studies, without reporting new clinical results.

This review suggests that low-level light therapy can promote hair growth in patients with androgenetic alopecia, but more research is needed to standardize treatment parameters and assess long-term safety and efficacy.

This review discusses the role of extracellular vesicles from specific skin cells in wound healing, emphasizing their potential in regenerative medicine and reporting no new experimental results.

This study found that canine adipose-derived mesenchymal stem cell-derived dermal papilla-like tissues promoted new hair follicle formation and increased vascularization in mice, suggesting potential for hair regeneration.

This review discusses studies on hair growth and protein synthesis in hair follicles, highlighting the differing responses of mohair and cashmere goat follicles to signaling molecules, biotin, and amino acids, but contains no new results.

This study found that silk fibroin/sodium alginate scaffolds seeded with dermal papilla cells may accelerate skin repair and hair follicle regeneration in a rat model.
