This article reviews the toxic effects of mimosine in Leucaena leucocephala and discusses various methods to mitigate its toxicity but presents no new findings.

In this study, researchers found that hair follicle-derived mesenchymal stem cells, modified to overexpress extracellular matrix protein 1, significantly improved liver function and reduced liver damage in cirrhotic mice by inhibiting hepatic stellate cell activation and TGF-β/Smad signaling.

This study found that UVB radiation significantly alters miRNA expression and induces cytotoxicity and apoptosis in normal human dermal papilla cells.

This study found that a novel 3D in vitro culture condition improved stemness markers and proliferation potential in human dermal stem/progenitor cells compared to traditional 2D methods.

This study found that the proteins GDNF, NTN, GFRα-1, GFRα-2, and c-Ret are differentially expressed during various stages of the human hair follicle cycle, with potential implications for hair biology.

This study reported that allethrin caused dose-dependent toxico-pathological effects, including decreased feed intake, body weight, and blood parameters, and organ damage in adult male albino rats.

This study found that the postnatal thymus contains a population of mesenchymal stem cells that may help maintain functional thymic microenvironments.

This study found that micro-current electrical stimulation may promote hair growth in human hair follicle-derived papilla cells and a mice model by enhancing cell proliferation, migration, and activating key growth pathways.

In this study, researchers established five new immortalized human dermal papilla cell lines from a male with androgenetic alopecia, which may serve as valuable tools for hair research.

This article discusses various infection control practices necessary in dermatology to minimize exogenous infection risk and reports no new clinical results.

This study reported that a novel chitosan/polyvinyl alcohol nanofiber sponge effectively enhances the hair follicle-inducing ability of dermal papilla multicellular spheroids in a mouse model.

This study observed that injecting a combination of human cultured dermal papilla and epithelial cells induced hair growth in a mouse model.

This source summarizes discussions by an advisory board of twelve experts on hair loss, focusing on heredity, aging, and environmental impacts, and emphasizing strategies that may slow alopecia.

This study found that Wnt ligands from CD133-positive dermal papilla cells are essential for maintaining hair growth by supporting cell signaling between different hair follicle structures.

Finasteride helps treat hair loss by blocking enzyme activity.

This review article summarizes the potential role of advanced medical therapies—using genes, cells, and/or tissue engineering—in treating various types of alopecia, by examining clinical research, basic studies, and ongoing trials.

This study found that both ethanol and aqueous extracts of Lepidium sativum seeds improved insulin signaling and reduced obesity-related metabolic changes in high-fat diet-fed rats, suggesting potential as a dietary supplement.

This study found that mackerel-derived fermented fish oil extract and its component DHA promote hair growth by activating anagen pathways in dermal papilla cells.

This study demonstrated that bioluminescence imaging of NG2+ cells in transgenic rats allows in vivo monitoring of hair follicle cycles to study hair growth and follicle regeneration.

This study observed that glycine inhibited root growth and stimulated root hair development in habanero pepper seedlings, with ethylene signaling suggested to mediate these effects.

This study's molecular dynamics simulations suggest that electrostatic interactions mainly stabilize peptide binding to human hair keratin, with the protein's dielectric constant significantly affecting free energy calculations.

This study found that exosomes from hair follicle mesenchymal stem cells overexpressing lncRNA H19 promoted diabetic skin wound healing by enhancing cell proliferation, migration, and reducing pyroptosis.

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 using cultured mesenchymal stem cells from mouse whisker hair follicle outer root sheath in wound healing reduced inflammation, accelerated closure, and resulted in less hypertrophic scarring in mice.

In this study, ethanamizuril was found to cause alopecia, biochemical changes, and organ damage at higher doses in rats, with a no-observed-adverse-effect level of 20 mg/kg over 30 days.

This study found that a titrated extract of Centella asiatica enhanced the hair growth potential of 3D spheroid cultured human dermal papilla cells.

This review discusses in vitro methods for evaluating the effects of hair care products on hair fibers, reporting no new results; the authors emphasize the importance of selecting appropriate and accurate equipment for testing.

This review discusses the emerging pathophysiological factors and potential new therapies for androgenetic alopecia beyond traditional treatments, but reports no new results.

This study reports that the tetrapeptide AcSDKP significantly promotes skin and hair health in vitro and ex vivo, suggesting it could be used cosmetically to counteract skin aging and hair loss.

This study found that red-flowered cultivars of Hibiscus rosa-sinensis displayed the highest antioxidant activity, phenolic, and flavonoid content compared to other colored cultivars.
