Problems and Solutions for Platelet-Rich Plasma in Facial Rejuvenation: A Systematic Review

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 found that DKK1 and WNT10b are paracrine factors that modulate hair follicle stem cell differentiation inhibition, contributing to androgenetic alopecia by affecting Wnt signaling in androgen-sensitive dermal papilla cells after dihydrotestosterone stimulation.

This study found that hydrogels supplemented with fractionated platelet-rich plasma recruited more dermal-derived stem cells and accelerated healing, leading to hair growth and skin regeneration in rats.

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 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 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.

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.

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 review discusses recent advancements in hair rejuvenation strategies and assesses the potential of herbal drugs as safer alternatives, but reports no new clinical results.

This article discusses the biologic and psychosocial significance of hair, the current limitations in hair growth drugs, and anticipates future therapies based on advancing hair follicle research.
