This study uncovered that bimatoprost, a prostaglandin analog, promotes hair growth by activating hair follicle progenitor cells through two pathways: the PTGFR-MAPK signaling axis and an unexpected IGF1R-PCAD-AKT signaling axis, suggesting new potential targets for treating hair disorders.

This review summarizes recent therapeutic advancements in treating various forms of alopecia, including new applications of oral minoxidil, dutasteride, finasteride, Janus kinase inhibitors, and novel hair transplant techniques, without presenting original research results.

This review discusses the molecular mechanisms of androgenetic alopecia and evaluates current and potential treatments, highlighting the limitations of minoxidil and finasteride and exploring newer approaches like growth factors and cytokines, topical 5-alpha-reductase inhibitors, and platelet-rich plasma injections as more effective and safer alternatives.

This review examines the molecular mechanisms and current treatment options for androgenetic alopecia, highlighting potential future therapies but providing no new experimental findings.

This study suggests that minoxidil activates PGHS-1, which may explain its hair growth-stimulating effects and could aid in designing more potent hair growth-promoting drugs.

This study found that Wnt3a increased beta-catenin signaling and upregulated specific genes in cultured human dermal papilla cells, enhancing their response to PGE2 and potentially aiding hair growth.

UV light might cause excessive hair growth by increasing PGE2 in the skin.

This study suggests that dsRNA may enhance KRT9 expression in palm and sole skin through β-catenin signaling, potentially linking mechanical damage to specific skin features and certain skin conditions.

This review discusses the role of Prostaglandin D2 and its synthase in androgenetic alopecia but reports no new clinical findings, suggesting pathways for future therapeutic development.

This review synthesizes knowledge on Prostaglandin E2's role in platelet biology and suggests that targeting PGE2 pathways could lead to personalized antiplatelet therapy without affecting hemostasis, but it presents no new results.

PGD2 stops hair growth and is higher in bald men with AGA.

This study found that latanoprost induces significant growth and pigmentation of lashes and ancillary hairs, with effects mirroring both brief and chronic treatments observed in patients and animal models.

This study found that PGD2 inhibits hair follicle regeneration in mice through the Gpr44 receptor, suggesting that blocking PGD2 or Gpr44 may enhance skin regeneration after wounds.

In this study, PGD2 was shown to increase testosterone production in human keratinocytes through reactive oxygen species, suggesting potential benefits of antioxidants like N-acetyl-cysteine for AGA patients.

This study found that increased levels of PGD2 and prostacyclin and decreased levels of PGE2 and PGF2α were associated with baldness in androgenetic alopecia, suggesting potential targets for treatment.

This study assessed Ageratum conyzoides gel's efficacy in reducing hair loss and improving quality of life in adults with pattern baldness, finding that it decreased temporal recession and improved hair-related distress scores, with a significant reduction in 5α-reductase expression and PGD2 release in vitro.

This study found that topical minoxidil modestly extended the anagen phase in mice by activating β-catenin activity in dermal papilla cells.

This study examined the structural and biochemical mechanisms of human lipocalin prostaglandin D synthase, detailing substrate and product binding processes at the catalytic site and suggesting potential for drug delivery targeting hydrophobic molecules.

This study reported that the PTGER2 gene is strongly expressed in cashmere goat skin and its expression tends to decrease from the anagen to telogen stages of the hair follicle cycle.

This study identified that blocking the PTGDR2 receptor in human hair follicles in vitro and in mice reversed the hair growth inhibition caused by PGD2, suggesting a potential approach for treating alopecia.

This study found that 1,25 dihydroxyvitamin D3 significantly increased the expression and activity of vasculoprotective natriuretic peptide receptor-A in cultured inner medullary collecting duct cells, suggesting a potential mechanistic role in cardiovascular and renal benefits.

The researchers reported that dsRNA from damaged skin activates TLR3, promoting hair follicle regeneration, while TLR3-deficient animals fail to initiate this process, suggesting potential therapeutic approaches for hair neogenesis.

This study found that castration-resistant prostate cancers resistant to CYP17A1 inhibitors may still depend on steroids and could respond to therapies targeting de novo intratumoral steroid synthesis.

This study found that KY19382 can effectively promote hair regeneration and follicle neogenesis in mice and human hair models by activating Wnt/β-catenin signalling, suggesting potential use for alopecia treatment.

In this study, topical methyl vanillate application increased hair count and hair mass index in women with androgenetic alopecia by enhancing WNT10B expression, suggesting a potential new treatment strategy.

This study found that phosphatidic acid promotes hair growth by stimulating cell proliferation and protecting against apoptosis in murine hair epithelial cells, unlike lysophosphatidic acid, which showed limited effects.

This review discusses recent therapeutic advances in treating various types of hair loss, including androgenetic alopecia, alopecia areata, frontal fibrosing alopecia, and hair transplant technologies, but reports no new clinical results.

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

This study found that dihydrotestosterone (DHT) suppresses prostaglandin E2 and TGF-β induced IGF-I gene promoter activity in osteoblasts, suggesting complex interactions among bone growth regulators and potential complications from anabolic steroid use.

This study examines the interaction between androgen receptor signaling and the β-catenin/Wnt signaling pathway in mouse hair follicles, but reports no clinical results.
