This study found that platelet lysate produced higher follicular regeneration in hair restoration surgeries compared to activated PRP and saline, with significant gains in both follicular unit and hair density.

This systematic review and meta-analysis found that platelet-rich plasma (PRP) therapy is effective in increasing hair density and reducing hair loss for alopecia, with variations in response based on activation status.

This article discusses the therapeutic use of platelet-rich plasma (PRP) in dermatology, specifically its challenges and potential in treating conditions like lichen planopilaris, but reports no new findings.

This review found that while platelet-rich plasma shows potential benefits for hair restoration, there is a lack of standardized preparation and treatment protocols, necessitating further rigorous trials.

This study found that the efficacy of platelet-rich plasma in treating androgenetic alopecia is higher with increased frequency of sessions, chemically-activated PRP, double centrifugation, and whole-head application, among younger and female patients.

This study suggests that platelet-rich plasma may provide short-term improvement in hair density for female pattern hair loss, but results varied and more rigorous trials are needed to establish optimal protocols.

Using micrografts with stem cells and platelet-rich plasma can safely and effectively help regrow hair.

In this study, activated PRP injections appeared to promote hair growth in AGA-affected scalp skin transplanted onto mice, compared to non-activated PRP.

In this study, 23 patients with androgenetic alopecia were treated with non-activated autologous platelet-rich plasma (A-PRP) administered through interfollicular injections, but the abstract provides no results of the treatment's effectiveness.

This study found that 5% activated platelet-rich plasma significantly improved cell proliferation and hair-inductive ability of dermal papilla cells in vitro, and promoted hair follicle formation in mice.

This study reports that using activated platelet-rich plasma releasate in the preparation of bioengineered hair follicle germs enhanced follicular gene expression and significantly improved hair regeneration in vitro.

This study found that non-activated platelet-rich plasma from acetylsalicylic acid-treated patients increased inflammatory cytokines, affecting platelet activation and possibly influencing outcomes in PRP therapies.

This study found that repeated applications of both nonactivated and activated PRP in rats led to increased hypersensitivity to pain, which may be linked to elevated nerve growth factor levels and inflammatory mediators.

The authors concluded that controlling voltage, pulse width, and calcium concentration in pulse electric field-activated platelet-rich plasma enhances the release of growth factors and serotonin without causing clot formation, suggesting potential clinical advantages over bovine thrombin-activated PRP.

In this study, researchers observed that activated platelet-rich plasma promoted hair growth in mice and increased cell proliferation in vitro, suggesting potential clinical applications for hair growth treatment.

In this study, researchers demonstrated that treating platelet rich plasma with microsecond pulsed electric fields effectively activates platelets and induces similar or higher growth factor release compared to traditional bovine thrombin, suggesting a potential clinical use that may be more cost-effective and practical.

This study found that injections of autologous platelet-rich plasma in patients with pattern hair loss were compared to placebo, but the abstract does not report specific clinical results.

This study found that intra-operative platelet-rich plasma therapy may enhance hair regrowth, increase graft density, and activate dormant follicles more effectively than normal saline in follicular unit extraction hair transplant patients.

This study found that applying 10% platelet-rich plasma significantly increased hair follicle density and reduced the time for hair formation in a mouse model compared to no PRP treatment.

This study found that autologous platelet-rich plasma increased hair growth potential by enhancing dermal papilla cell proliferation and stimulating key signaling pathways in both cell cultures and mice models.

In this study using a mouse model, the researchers found that platelet-rich plasma significantly increased the number of newly formed hair follicles and decreased the time for hair formation compared to no treatment.

PRP treatment increased hair density, especially in men and younger patients with AGA.

This review discusses the use of platelet-rich plasma for pattern hair loss treatment and examines existing clinical studies without presenting new clinical results.

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.

This study found that hair thickness and density increased after treatment with human follicle mesenchymal stem cells and platelet rich plasma, associated with enhanced Wnt signaling and platelet derived growth factors.

This review discusses the use of platelet-rich plasma (PRP) in clinical settings and notes the lack of standardization and consensus on its preparation and use; it reports no new clinical results.

This study suggests that platelet-rich plasma's high levels of growth factors may be limited in promoting bone regeneration due to the concurrent release of Dickkopf-1, which inhibits osteogenesis.

This study reviews various factors affecting mesenchymal stem cell transplantation efficacy, including platelet concentrate composition, donor characteristics, and environmental influences, and examines strategies for optimizing outcomes through preconditioning and combined therapies in regenerative medicine.

This review discusses the composition, preparation, and applications of autologous platelet and extracellular vesicle-rich plasma, highlighting its potential benefits and the need for further research, but it reports no new clinical findings.

This article reviews the use of autologous platelet-rich plasma (PRP) in hair restoration, discussing its potential benefits for follicle health and regeneration, but it reports no new clinical findings.
