Borate-Modified Recombinant Type XVII Collagen Microneedles Loaded with IGF-1 for the Treatment of Androgenetic Alopecia

This study found that dissolving microneedles loaded with platinum nanozymes induced faster hair growth in an androgenetic alopecia model than daily minoxidil applications, with no significant safety concerns.

In a study using an AGA mouse model, researchers observed that a novel topical gel combining hybrid extracellular vesicles, gold nanoparticles, and finasteride accelerated hair regrowth and improved hair quality more effectively than conventional minoxidil treatment, presenting a promising option with fewer side effects.

In this study, researchers found that the interaction between dermal papilla and endothelial cells decreases with age, affecting signaling pathways that promote hair regeneration and angiogenesis in mouse models.

This study found that a microneedle system delivering VEGF and Ritlecitinib improved hair regeneration in mice with androgenetic alopecia, showing faster anagen onset and better hair quality compared to minoxidil.

This study developed a delivery platform using hyaluronic acid-based dissolvable microneedles with nanoliposomes containing kopexil and kopyrrol, which showed improved hair regeneration for treating androgenetic alopecia in vivo at lower dosages compared to minoxidil.

In a mouse model of androgenetic alopecia, this study developed a treatment combining a copper-curcumin nanoparticle oleogel with traditional Gua Sha therapy, which augmented hair regeneration more effectively than minoxidil by improving the follicular microenvironment and regulation of inflammatory responses.

This study developed a novel liposome-based delivery system for Minoxidil and nitric oxide, which showed promising results in promoting hair regrowth in an androgenetic alopecia model by enhancing transdermal absorption, prolonging skin retention, and reducing inflammation.

In this study, miR-221 was identified as a key factor in androgenetic alopecia pathogenesis due to its role in suppressing hair growth by interacting with androgen receptors and affecting related pathways.

This study reported significant improvements in hair density, diameter, and patient satisfaction after using non-enzymatic stromal vascular fraction treatment for androgenic alopecia over six months.

This study found that collagen peptides from Mozambique tilapia significantly promoted hair regrowth and increased the proliferation of hair growth factors in vitro and in vivo, suggesting potential as supplements for hair loss prevention.

In this study, a microneedle patch containing conditioned media from hypoxia-pretreated stem cells enhanced hair regeneration in an androgenetic alopecia mouse model by boosting perifollicular vascularization and hair follicle stem cell activation compared to minoxidil.

This review article highlights how hair follicle-targeting drug delivery systems enhance therapeutic outcomes and reduce side effects for treating conditions like androgenetic alopecia and acne vulgaris. The authors discuss current formulations and evaluate their performance in both preclinical and clinical settings.

In this study, Cyanidin 3-O-arabinoside was found to protect against DHT-induced dermal papilla cell senescence and mitochondrial dysfunction in androgenetic alopecia, restoring hair growth in mouse models.

This review discusses the role of collagen XVII in maintaining stem cell niches and its impact on skin aging and wound repair, without reporting new clinical results.

This review reports that clinical studies generally showed favorable results for microneedling as an adjunct therapy for androgenic alopecia and alopecia areata, despite the low quality of existing data.

This study found that microneedling monotherapy significantly increased hair count more than topical minoxidil in androgenetic alopecia, with combination therapy of microneedling and minoxidil being even more effective. Further research is needed to evaluate microneedling's safety and efficacy as a monotherapy.

This study found that a ceria nanozyme-integrated microneedles patch accelerated hair regeneration in an androgenetic alopecia mouse model more effectively than minoxidil, with reduced application frequency and minimal skin damage.

In this study, ALRV5XR significantly increased hair regrowth in women with androgenetic alopecia or telogen effluvium, with no adverse events reported.

In this study, exosome-mimetic nanovesicles derived from neural progenitor cells promoted hair follicle regeneration in mice by activating the Wnt/β-catenin signaling pathway.

This study generated FGF5-knockout Dorper sheep using the CRISPR/Cas9 system, resulting in significantly increased fine-wool and active hair-follicle density, and explored downstream signaling pathways for potential applications in androgen alopecia treatment.

This study found that COL17 deficiency in neonatal mice causes abnormal skin cell proliferation due to disrupted Wnt signaling, while replenishing or overexpressing COL17 can reverse this effect in both neonatal and aged skin.

This review discusses completed and ongoing clinical studies on microneedle-based technologies for cosmetic, therapeutic, and diagnostic applications and reports no new clinical results.

This research found that Foxc1 transcription factor and COL17A1 are critical in regulating quiescence and hair thinning in hair follicle stem cells, with aging-related DNA damage leading to hair loss.
