PRP: Is There a Valid Role in Hair Loss Treatment?

This review examines the efficacy of platelet-rich plasma for treating hair loss, highlighting the lack of standardized protocols for PRP preparation and delivery and reporting no new clinical results.

This study found that platelet-rich plasma injections promote hair growth and are safe and effective for treating androgenetic alopecia.

In this study, autologous non-activated platelet-rich plasma was associated with greater hair re-growth than autologous activated platelet-rich plasma over long-term follow-up.

This article discusses platelet-rich plasma (PRP) therapy for hair loss and reports no clinical results; it highlights the need for further research to understand its effectiveness.

In this study, researchers found that the variability in growth factor expression, particularly TGFβ1, in PRP samples could influence patient responses to hair loss treatment with PRP therapy.

This review suggests that platelet-rich plasma may be effective in increasing hair density in patients with androgenetic alopecia, but more research is needed to determine the best treatment protocol.

This meta-analysis suggests that local injection of platelet-rich plasma for androgenic alopecia is associated with an increased number of hairs and some increase in hair thickness, though larger studies are needed for confirmation.

This study reviewed two blinded randomized controlled trials and one prospective cohort study and found that PRP injections may increase hair density and induce hair regrowth in adults with androgenic alopecia and alopecia areata, with notably higher hair counts reported at specific follow-up intervals.

This review evaluates the therapeutic potential of platelet-rich plasma for treating non-cicatricial alopecias and suggests it may be effective, though further research is needed to confirm its efficacy.

PRP treatment showed no hair regrowth improvement after the first application in patients with alopecia.

This article discusses objective methods for assessing hair loss and notes that most types of hair loss can regrow without treatment, but effective treatments for pattern or senescent alopecia remain unavailable.
