Activated Platelet Rich Plasma Versus Non-Activated Platelet Rich Plasma in the Treatment of Alopecia Areata

This review discusses the potential use of platelet-rich plasma for treating alopecia areata but reports no new experimental findings, noting the need for standardized protocols and larger studies to evaluate its efficacy.

This article discusses the use of platelet-rich plasma as a supportive treatment for hair loss, emphasizing its potential to enhance hair follicle health and patient satisfaction, but reports no new clinical results.

This review noted that alopecia areata is an autoimmune disease impacting hair follicles and offered insights into its complex pathogenesis involving immune responses, while highlighting ongoing research into new treatments such as Janus kinase inhibitors and other immunomodulatory drugs.

This study observed that autologous platelet-rich plasma treatment improved hair count and density in areas with androgenetic alopecia compared to placebo, with differing outcomes based on the PRP collection device used.

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 study suggests that CD8+ cytotoxic T lymphocytes play a crucial role in the development of alopecia areata, based on observations in rodent models that mimic human autoimmune disease.

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.

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 article reviews the clinical presentation and histopathologic features of alopecia areata and proposes a hypothesis for its development, but it reports no new clinical results.

In this study, platelet plasma growth factors from patients' autologous plasma improved follicular unit yield in baldness surgery by 15.1% compared to control areas.
