Hair Therapy: Platelet-Rich Plasma

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.

Platelet-rich plasma shows potential for hair growth, but more research is needed to determine the best preparation method.

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 study found that platelet-rich plasma injections significantly improved hair density, thickness, and patient satisfaction in women with female pattern hair loss compared to a placebo.

This article reviews various hair growth and hair loss treatments, noting limited new developments since FDA-approved drugs but highlights recent cosmetic surgery and potential cell-based therapies; it reports no original findings.

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.

In this study, platelet-rich fibrin matrix combined with follicular unit transplantation increased hair follicle numbers in men with androgenetic alopecia on the treated side of the scalp after six months.

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.

Mesotherapy and platelet-rich plasma treatments may help with hair loss, but their safety and effectiveness are still uncertain.

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.
