This study investigated the effects of the 60% alcohol extract from Alnus sibirica and its active compound, oregonin, on hair health, observing anti-oxidative and anti-apoptotic benefits in human hair dermal papilla cells exposed to oxidative stress, suggesting potential as natural materials for hair loss prevention.

This review discusses how neuroendocrine regulation affects human hair follicles and suggests potential therapeutic targets, but it reports no new clinical results.

Among in vitro and in vivo models, this study found that Miscanthus sinensis var. purpurascens flower extract may promote hair growth, potentially by modulating growth factor expressions and facilitating earlier hair follicle transitions in treated mice.

This study found that men with androgenetic alopecia had significantly higher plasma leptin levels, which were associated with an increased risk of developing the condition.

In this study, the methanol-ultrasound extract of Dendropanax morbifera leaf showed potential for use in functional cosmetics and hair growth products due to its high antioxidant capacity and effects on growth factor expression without cytotoxicity.

This study found that KH053, combining Panax ginseng and bee-pollen, significantly reduced prostate weight and DHT levels, inhibiting BPH development in a rat model.

This study found that TGF-β1 expression in follicular tumors correlates with differentiation degree and suggests its potential role alongside p63 in differentiating between sebaceous and follicular tumors.

This study found that injecting keratin into the skin of mice promoted hair growth, potentially through keratin's interaction with hair-forming cells and changes in the microenvironment.

This study identified 21 novel circular RNAs in cashmere goats, with nine significantly more expressed during the anagen phase of hair follicle growth, suggesting roles in hair regeneration and cashmere yield enhancement.

This study found that Hetian sheep with higher wool density produce more and finer wool, with key genes potentially influencing their wool growth and density.

This study suggests that the herbal formulation Phyllotex™ may promote hair growth in androgenetic alopecia by enhancing cell proliferation and reducing oxidative stress and TGF-β1 expression in vitro.

This study found that Nelumbinis Semen extract may promote hair growth and reduce hair loss by increasing VEGF and IGF-1 expression and decreasing TGF-β1 in human dermal papilla cells and mice.

This study observed that the OCIAD2 and DCN genes in Liaoning cashmere goats have opposite effects on hair growth by interacting with the TGF-β signaling pathway, influencing follicle morphogenesis and periodic changes.

This study found that 6-Gingerol significantly suppressed hair growth in mice by reducing hair follicle number and length, potentially through increased expression of MMP2 and MMP9.

This article discusses the early development of hair follicles with a focus on the formation of epidermal thickenings called placodes, reporting no new experimental results.

This article discusses how nutritional and environmental factors, along with antioxidant supplementation, may improve hair growth by mitigating the effects of androgens and reports no new clinical results.

This study reported that the use of composite RGDmix hydrogel improved the survival and proliferation of human amniotic mesenchymal stem cells and increased growth factor expression, enhancing wound healing through the RGDSP/integrin αv/PI3K/AKT signaling pathway.

This study found that transplanting hair follicles into human scars may remodel fibrotic tissue and reduce scarring by altering collagen structure and decreasing pro-fibrotic factors.

This review discusses the biological effects of honokiol for treating skin diseases and reports no new clinical results; the authors recommend further exploration of topical applications.

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 radiation exposure in male rats activated hepatic stellate cells and the PI3K/Akt signaling pathway, mediated by TGF-β1, contributing to liver injury, while the use of a signaling pathway inhibitor reduced these effects.

This review discusses the use of platelet-rich plasma for treating various types of alopecia, reporting promising preliminary hair regrowth results but noting a lack of quantitative evidence from well-designed clinical trials.

In this study, researchers identified 32 differentially expressed genes involved in androgenetic alopecia, with down-regulated genes associated with Wnt and TGF-beta signaling and up-regulated genes linked to oxidative stress pathways.

This study found that RCS-01 cell therapy for aged skin was well tolerated and associated with increased gene expression related to extracellular matrix homeostasis, suggesting potential skin improvement.

This study observed that gerbils exhibit a different wound healing mechanism compared to mice, with lower TGF-B1 expression and distinct tissue responses, yet achieve similar healing outcomes.

In this study, adipose-derived stem cells from human scalp were successfully directed towards chondrocyte differentiation, with TGF-beta3 and BMP-6 growth factors proving effective for in vitro chondrogenesis.

In this study, TASP0382088 showed potent selective inhibition of the ALK5 receptor, significantly reducing Smad2 phosphorylation in mouse skin following topical application.

This study used transgenic mice to show that disrupting TGF-β signaling in K14+ progenitor cells led to increased stem cell proliferation in the tongue.

The study characterized the transcriptional changes in porcine SKP cells transitioning to fibroblast-like cells, indicating potential roles for specific signaling pathways in this cell fate transition.

This study suggests that TGF-alpha may function in an autocrine or juxtacrine manner rather than promoting cell proliferation during hair growth cycles in ferrets and sheep.
