Platelet-Rich Plasma (PRP): How Blood Factors Boost Hair Regrowth
Discover how your own platelets can activate follicle stem cells and stimulate natural regrowth.
Platelet-Rich Plasma therapy, known as PRP, uses a patient’s own blood to stimulate hair growth. This study investigates how growth factors in PRP influence follicle stem cell regeneration.
- PRP injections increased hair shaft thickness by up to 30%.
- Platelets release growth factors such as VEGF and PDGF that trigger angiogenesis.
- Repeated sessions every 3–6 months showed sustained results.
- Minimal side effects were reported, making PRP a low-risk procedure.
PRP bridges the gap between medical and regenerative therapy — harnessing the body’s healing potential to address hair thinning naturally. It also helps clinicians personalize care based on a patient’s platelet concentration and scalp health.
Results vary by preparation method and injection depth. Standardized protocols are needed to ensure consistent outcomes.
Studies are exploring combining PRP with microneedling or exosomes to enhance efficacy.
