Injectable Platelet-, Leukocyte-, and Fibrin-Rich Plasma in the Management of Androgenetic Alopecia

This review suggests that PRP injections may be effective in promoting hair regrowth, reducing hair loss, and increasing hair thickness in patients with androgenic alopecia.

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 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 did not significantly improve hair mass index or hair count in women with female androgenetic alopecia, though some patients perceived benefits in hair quality.

This review discusses the use of platelet-rich plasma for pattern hair loss treatment and examines existing clinical studies without presenting new clinical results.

This study found that platelet-rich plasma significantly increased hair density and anagen hair proportions in androgenetic alopecia patients, suggesting potential as an adjuvant therapy.

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 injections may improve hair loss condition, but more research needed.

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.

In this study, intradermal injections of autologous platelet-rich fibrin matrix significantly increased hair density in patients with androgenetic alopecia at 2 and 3 months after initial treatment.

In this study, PRP injections increased hair count and reduced hair loss in patients with androgenic alopecia not responding to minoxidil and finasteride, with high patient satisfaction reported.

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.

This study found that interfollicular injection of autologous CD34+ cell-containing PRP preparation improved hair count and thickness in patients with pattern hair loss, with better results than placental extract treatment.

PRP helps hair growth in common hair loss disorder.

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

This article discusses the principles and considerations of clinical photography for hair disorders in dermatology, reporting no new clinical findings.

This study concluded that TrichoScan is error-prone in its current form and overestimates certain hair growth parameters, with results not aligning with clinical severity of alopecia.

This study reported that Trichoscan, a computer-assisted hair measurement system, was not supported as accurate for clinical trials due to errors in signal detection, despite its analysis speed.

This review discusses various methods for measuring scalp hair growth in androgenetic alopecia and reports no new results; the authors suggest that computer-assisted technology has untapped potential.
