This study found that an exosome formulation with plant extracts significantly increased hair regrowth in men with male pattern alopecia compared to a placebo, without notable adverse effects.

In this study using C57BL/6 mice, the researchers observed that combining minoxidil with exosomes and DNA polynucleotides improved hair follicle density and promoted gene expression linked to hair growth, suggesting enhanced hair growth potential over minoxidil alone.

In this laboratory study, the researchers found that combining dermal papilla cell-derived exosomes with collagenous sequences significantly enhanced hair follicle stem cell migration and proliferation, highlighting a potential strategy for hair regeneration through modulation of the hsa-novel-238a-CASP9 axis.

This review highlights the multifunctional role of exosomes in dermatology, noting their potential as therapeutic agents for conditions like skin cancers and hair disorders, while also indicating pathogens exploit them for immune evasion.

In this research, preclinical and early clinical studies on exosomes indicate their potential to modulate wound healing, skin rejuvenation, and hair growth in facial plastic surgery, but these treatments remain experimental until receiving FDA approval and robust clinical validation.

This study found that decorin treatment significantly enhances dermal papilla cell proliferation, promoting hair follicle growth by influencing the SMAD3/TGF-β signaling pathway through exosomal miR-129–2-3p, which may aid in novel strategies for treating hair disorders and enhancing wool production.

This report describes an eight-year-old girl with severe hair shaft abnormalities who showed significant improvement after a single session of adipose tissue–derived exosome therapy, highlighting its potential as an innovative treatment option and the need for further studies to confirm its efficacy and safety.

This case study examined the treatment of female-pattern androgenetic alopecia using a protocol combining photodynamic therapy and topical Damask rose stem cell-derived exosomes, suggesting potential benefits for integrating these methods into standard care to enhance therapeutic outcomes and patient satisfaction.

This study found that exosomes derived from hair follicle neural crest stem cells significantly promoted nerve regeneration in injured neurons, particularly when overexpressing miR-214-3p, which enhanced axon extension and motor function recovery in both in vitro and in vivo models.

This review critically assesses recent evidence (2020-2025) on the effectiveness of regenerative therapies like platelet-rich plasma, photobiomodulation, stem cells, and exosomes for treating androgenetic alopecia, highlighting the challenges physicians face due to commercialization and the evolving regulatory landscape.

In this case study, a 14-year-old male with treatment-resistant diffuse alopecia areata experienced complete hair regrowth after three monthly sessions of microneedling combined with triamcinolone, dutasteride, and synthetic exosomes, suggesting this therapy might enhance outcomes in refractory cases.

In this study, researchers compared several commercial products for facial skin repair and found that only the product containing exosomes purified from bovine colostrum showed positive effects on cell proliferation, viability, and wound repair in vitro, outperforming untreated samples and other tested products.

This study demonstrated that exosomes from human hair follicle mesenchymal stem cells can enhance collagen production, promote cell proliferation and migration in human dermal fibroblasts, and reverse signs of UV-induced skin aging in mice, potentially via a miR-125b-5p/TGF-β1/Smad signaling pathway.

In this phase I/II clinical trial, placenta-derived mesenchymal stem cell exosome therapy significantly improved hair density and diameter, and reduced hair loss in patients with androgenetic alopecia, though further large-scale studies are needed to confirm these results and investigate the underlying molecular mechanisms.

In this case series, mesenchymal stem cell exosomes were reported to improve hair length, density, pigmentation, and cuticle layer recovery in three patients with acquired trichorrhexis nodosa, suggesting potential as a therapeutic approach for this hair condition.

This study found that exosomes derived from bovine colostrum, compared to those from human stem cells, significantly increased hair follicle growth and regeneration in vitro.

This study found that umbilical cord mesenchymal stem cell-derived exosomes improved hair growth in mice with androgenetic alopecia by promoting hair follicle stem cell stemness through the RAS/ERK pathway, suggesting a potential new treatment strategy for this condition.

In this multicenter observational study, researchers found that using micrografts with human follicle mesenchymal stem cells increased hair density significantly in both male and female patients with mild to moderate androgenic alopecia after 12 months, suggesting a viable alternative for hair regrowth.
