Update on Platelet-Rich Plasma

This review discusses the potential mechanisms of platelet-rich plasma in facial rejuvenation and reports no new clinical results, indicating a theoretical basis for its use in tissue regeneration.

This review summarizes clinical and comparative trials on platelet-rich plasma in dermatology and concludes that while PRP shows significant improvements, more randomized controlled trials are needed to confirm its effectiveness for widespread use.

This randomized prospective study found that microneedling combined with autologous platelet-rich plasma resulted in significant hair regrowth and reduction in SALT score after 12 weeks in patients with chronic and stable alopecia areata, suggesting it as a safe and efficient treatment option.

This meta-analysis reported that platelet-rich plasma injections for androgenetic alopecia may increase hair number and thickness locally, but further studies are needed to establish their overall effectiveness.

This review discusses the varied use and inconsistent reporting of platelet rich plasma in aesthetic surgery, finding that current studies lack consistent methodologies and objective evidence, and reports no new clinical results.

This study found that platelet-rich plasma was more effective for treating alopecia areata than topical 5% minoxidil, leading to earlier hair regrowth and reduction in hair abnormalities.

This analysis suggests that platelet-rich plasma therapy may be promising for treating androgenetic alopecia, but further controlled trials with standardized measures are needed to confirm its efficacy.

This case report describes a patient with corticosteroid-resistant ophiasis alopecia areata who experienced prompt hair regrowth after receiving platelet-rich plasma injections.

This study found that platelet-rich plasma may have a role in treating chronic alopecia areata, but more long-term follow-up studies are needed to confirm its effectiveness and success rate.

This study found that treatment with platelet-rich plasma showed some hair re-growth in patients with severe alopecia areata, but results were not sustained and treatment was associated with pain and discomfort.

In this study, platelet-rich plasma significantly increased hair regrowth and reduced symptoms of alopecia areata compared to triamcinolone acetonide or placebo, with no observed side effects.

This review examines platelet-rich plasma's applications in aesthetic surgery and reports no new clinical results; the authors highlight its growing use and potential as a therapeutic modality.
