Platelet-Rich Plasma in Hair Loss—Mechanism, Preparation, and Classification

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 review discusses the use of platelet-rich plasma as a treatment for androgenetic alopecia and highlights the need for standardized protocols, reporting no new clinical results.

This guideline review by the European Dermatology Forum evaluates current treatments for androgenetic alopecia but reports no new research findings, aiming to assist dermatologists in selecting safe and effective therapies.

This review discusses the use of platelet-rich plasma in dermatology for various applications such as tissue regeneration and wound healing, but it reports no new clinical results and calls for clearer guidance on suitable treatments.

This systematic review and meta-analysis found that minoxidil, finasteride, and low-level laser light therapy significantly improve hair growth in men with androgenetic alopecia, while minoxidil is also effective for women, compared to placebo.

This study found no significant benefit from PRP injections for treating androgenetic alopecia in men, highlighting the need for larger, well-designed trials to assess its effectiveness and safety.

This article proposes a mechanistic model for how platelet-rich plasma therapy may stimulate hair growth in androgenetic alopecia by promoting vascularization and activating specific signaling pathways, but it reports no new experimental results.

This study found that platelet-rich plasma injections significantly increased hair count and density in patients with male pattern hair loss without major side effects, suggesting it may be a safe and effective treatment option.

This study found that platelet-rich plasma injections led to improvements in hair counts, thickness, and strength in patients with androgenic alopecia, showing promise as an effective treatment with no major adverse effects.

This pilot study suggests injecting platelet-derived growth factors into the scalp may offer some clinical benefits for androgenetic alopecia, though further randomized trials are needed for confirmation.

This review discusses current therapeutic targets and treatments for androgenic alopecia but reports no clinical results; the authors highlight the challenge of developing multi-target drugs for effective treatment.

This study reported that AA-PRP injections significantly increased hair count and density in individuals with pattern hair loss compared to baseline, demonstrating their potential for enhancing hair growth.

This study found that PRP injections may improve hair density and reduce hair loss in patients with androgenetic alopecia without significant side effects, but further research is needed to confirm efficacy.

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.

In this study, researchers showed that Wnt ligands secreted by hair follicle epithelium are crucial for hair follicle regeneration and may be significant for treating hair disorders like alopecia.

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.

This study found that PRP combined with dalteparin and protamine microparticles may enhance hair growth by increasing hair thickness compared to PRP alone.

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.
