learn Platelet-Rich Plasma

growth factors taken from your blood and injected into your scalp to stimulate hair

What is Platelet-Derived Growth Factor Beta Polypeptide, and how does it help stimulate new hair growth? PDGF-BB is a growth factor that signals to dermal papilla cells and promotes blood-vessel formation; mouse studies report it can push follicles into the growth phase, and human evidence comes only indirectly from PRP trials. No PDGF product is approved for hair restoration and there is no published human trial of PDGF-BB on its own.
Is Platelet-Rich Plasma more effective when combined with topical treatments or supplements? Combining Platelet-Rich Plasma with topical treatments often enhances hair growth results.
What exactly is Platelet, and why is it popular for treating hair loss? Platelet-rich plasma therapy uses your own blood to stimulate hair growth.

research Platelet-Rich Plasma-Derived Exosomes Modulate Follicular Regeneration: A Comparative Mechanistic Analysis with Minoxidil in a Preclinical Model of Androgenetic Alopecia

September 2025 in “Bioscientia Medicina Journal of Biomedicine and Translational Research”

In this study, PRP-derived exosomes significantly outperformed minoxidil in promoting hair regeneration in a murine model of androgenetic alopecia, with the combination of both treatments showing enhanced follicular regeneration and increased markers of tissue proliferation and Wnt signaling pathway activity.

research Platelet-rich plasma-derived exosomes stimulate hair follicle growth through activation of the Wnt/β-Catenin signaling pathway

April 2025 in “Regenerative Therapy”

This study found that PRP-Exos may stimulate hair follicle growth and enhance regeneration in cases of AGA by activating the Wnt/β-Catenin signaling pathway, showing potential both in vitro and in vivo.

research Effects of Adipose-Derived Stem Cells and Platelet-Rich Plasma Exosomes on The Inductivity of Hair Dermal Papilla Cells.

5 citations , October 2021 in “PubMed”

This study found that exosomes derived from human adipose stem cells significantly enhanced the proliferation and migration of dermal papilla cells compared to those from platelet-rich plasma, suggesting potential benefits for hair loss treatment.

research Exosomes derived from platelet-rich plasma promote hair regeneration by regulating the SIRT1/FoxO3a pathway to alleviate oxidative stress

August 2025 in “Regenerative Therapy”

In this study, researchers observed that platelet-rich plasma-derived exosomes significantly promoted hair regeneration in a murine model of alopecia by enhancing hair follicle stem cell activities and modulating the SIRT1/FoxO3a pathway, suggesting potential clinical benefits for alopecia treatment.

research Therapeutic Potential of Extracellular Vesicles (Exosomes) Derived From Platelet‐Rich Plasma: A Literature Review

December 2024 in “Journal of Cosmetic Dermatology”

This study found that exosomes derived from platelet-rich plasma show preclinical promise for wound healing but lack sufficient data for other dermatological uses like hair growth and skin rejuvenation.
