This study found that garlic exosomes induced hair growth in rats by increasing anagen follicle counts and activating multiple signaling pathways, including Wnt-1, β-catenin, and TGF-β1.

This study found that SM04755, a novel topical drug, inhibited inflammation, keratinocyte proliferation, and fibrosis in vitro and improved skin health in a mouse model of psoriasis, indicating potential as a topical psoriasis treatment.

This study found that macrophages near hair follicles contribute to the activation of skin epithelial stem cells in mice, suggesting a novel role for macrophages in regulating hair growth.

The authors concluded that the dermal response to epidermal Wnt/β-catenin signaling depends on distinct fibroblast lineages, with each responding to different paracrine signals such as Hedgehog and TGF-β.

This study found that valproic acid promoted hair re-growth in C3H mice by activating the Wnt/β-catenin pathway, suggesting its potential as a treatment for alopecia.

This review discusses the regulation and dynamics of the Wnt/β-catenin signaling pathway in development, pluripotency, and cancer, highlighting potential mechanisms and future research directions, but reports no new results.

This study found that Runx1 in hair follicle stem cells modulates lipid metabolism, impacting membrane organization and enhancing signal transduction for cell proliferation in both normal and cancer epithelial cells.

This study found that Alpinetin, applied topically in C57BL/6J mice, promoted hair regeneration by activating hair follicle stem cells through Wnt signaling, extending the anagen phase and increasing hair shaft length, with no cytotoxicity observed in keratinocytes and fibroblasts.

This study found that tectoridin, an isoflavone from Rhizoma Belamcandae, may stimulate hair growth by activating Wnt signaling in human and mouse cell cultures.

This review discusses recent advances in hair regeneration strategies, including mechanical stimulation and complementary therapies like MSC transplantation and platelet-rich plasma, and reports no new clinical results.

In this study, Aminoacridine, Abemaciclib, and the combination of Aminoacridine with Minoxidil showed potential for effective hair regeneration by activating Wnt/β-catenin signaling in animal experiments.

This study found that active BMP signaling prevents epithelial stem cell activation and expansion in hair follicles, while its inhibition leads to HF stem/progenitor cell overproduction and matricomas.

This laboratory study found that activated platelet‐rich plasma supernatant enhanced hair growth signaling pathways in cultured human dermal papilla cells, suggesting potential for treating androgenic alopecia.

This study found that millet seed oil effectively promoted hair growth in a mouse model with testosterone-induced hair growth inhibition, suggesting its potential use in preventing or treating androgenetic alopecia.

This review discusses the reuse of molecular mechanisms involved in embryonic skin development for maintaining adult epidermal homeostasis and reports no new results.

This review discusses the molecular mechanisms of androgens and androgen receptors in skin disorders, particularly androgenetic alopecia, and reports no new clinical results; it highlights potential areas for future treatment development.

This study found that baicalin activates Wnt/ß-catenin signaling in human dermal papilla cells, increasing alkaline phosphatase expression, growth factor expression, and promoting hair growth in mice.

This chapter hypothesizes that vitamin D signaling in the skin may suppress UV radiation-induced epidermal tumor formation, reviewing potential mechanisms without reporting new clinical results.

This review examines the pharmacological potential of quinoline alkaloids from Cinchona bark for developing new drugs and cosmetics but reports no new findings.

This study found that DHT induces apoptosis in human keratinocyte cells via ERK activation, independently of androgen receptors and the Wnt/β-catenin pathway.

In this study, researchers developed a novel nucleic acid nanoparticle system incorporating quercetin, which they found enhances functional hair follicle regeneration and maintains epithelial structure stability in androgenetic alopecia by regulating hair follicle stem and dermal papilla cells.

This study showed that vitamin D receptor gene-deficient rats exhibit hair loss and skin abnormalities due to differences in gene and protein expression patterns, while ligand-independent VDR action is crucial for normal hair cycle maintenance and skin formation.

This study demonstrated that a ligand-independent action of the vitamin D receptor significantly affects keratinocyte behavior in hair follicles and skin, pointing to its crucial role in maintaining normal hair and skin structures in rats.

This study found that Enz_MoriL, a compound derived from Morus alba L., promotes hair follicle cell proliferation by affecting the Wnt/β-catenin pathway and can counteract an alopecia areata-like condition by suppressing the JAK-STAT signaling in human hair follicle dermal papilla cells.

In this study, deleting the -catenin gene in vitamin D receptor-null mice did not prevent tumor development, suggesting -catenin's predicted protective role was not observed.

This study found that overexpression of Wnt1a in bone marrow mesenchymal stem cells enhanced mouse hair follicle regeneration and promoted hair cycling.

In this study, researchers found that activating the delta opioid receptor with a specific agonist significantly promoted hair growth in mice, suggesting potential for developing new hair-loss treatments.

This study, published in "Más Dermatol," explores how multiple factors contribute to hair loss, such as genetics, hormones, oxidative stress, microinflammation, and emotional stress, and highlights interventions targeting these causes to improve hair regrowth and quality of life.

This study found that enteroendocrine cells play a key role in coordinating stem cell migration towards wounds in the Drosophila intestinal epithelium, aiding tissue repair through non-canonical Wnt signaling.
