PRP — your own plasma with platelets and growth factors. PDRN — standardized fragments of salmon DNA. Different molecules, different mechanisms, and in trichology, they are more often combined than compared.

PRP (Platelet-Rich Plasma, plasma lifting) is the injection of your own plasma enriched with platelets and growth factors. Blood is drawn from a vein and centrifuged to isolate plasma with a high concentration of platelets. PDRN (polynucleotides) are injections of standardized fragments of trout/salmon DNA. PRP is an autologous product, and its composition depends on the quality of your blood. PDRN is a factory-produced product with a fixed dosage. In trichology, both are used for androgenetic alopecia, diffuse hair loss, and to increase density, but through different mechanisms. PRP has a stronger concentration of platelet growth factors (PDGF, EGF, IGF-1). PDRN has a stronger anti-inflammatory and vascular effect through A2A receptors. They are often used together in one course. There are contraindications.
PRP is the first-line choice for early androgenetic alopecia, diffuse hair loss, and preparation for hair transplantation. It is also suitable as an affordable support course. PDRN is the choice for sensitive or inflamed scalp, for those refusing blood draws (fear of needles, poor veins), in cases of anemia, and during recovery after childbirth (after lactation is completed). In severe cases, the doctor often combines: 4 sessions of PRP + 2 sessions of PDRN, or alternates them over 3–6 months. If indicated, mesotherapy and/or exosomes are added.
PRP is obtained from your blood: 10–20 ml of venous blood is centrifuged to isolate plasma with a platelet concentration 3–5 times higher than normal. Platelets release growth factors (PDGF, EGF, IGF-1, VEGF) that activate follicles. The concentration and quality depend on your blood parameters — hemoglobin, platelets, overall condition. PDRN is a factory product made from ultra-purified trout/salmon DNA. Long chains of nucleotides are broken down in the skin into fragments that bind to A2A receptors on fibroblasts and endothelium. This activates collagenogenesis, angiogenesis, and suppresses inflammation (TNF-α, IL-6). The dosage of PDRN is always the same — it does not depend on your blood.
It depends on the situation. With good hemoglobin and early alopecia, PRP provides a strong effect. With an inflamed scalp or anemia, PDRN works better. In clinical practice, they are often combined rather than choosing one.
Yes, this is standard practice. Usually alternating: one session of PRP, the next — PDRN, with an interval of 2–3 weeks. Or first 2 sessions of PRP, then 2 sessions of PDRN.
PRP — 60–80 AZN per session, significantly cheaper. PDRN — 300–400 AZN. The difference of 4–5 times reflects the difference in technology: PDRN is a factory product, PRP is made from your blood in 15 minutes.
PDRN is usually better after childbirth. It does not require blood draws (which can be uncomfortable in cases of possible anemia), and is safer during overall recovery. But not during lactation — typically after it is completed.
Reduction in hair loss with both PRP and PDRN is usually seen after 1–2 sessions. Thickening and visible hair growth occurs 2–3 months after the course is completed.
No. Both PRP and PDRN are adjunct therapies that enhance the density and quality of existing hair. In cases of pronounced androgenetic alopecia, they are combined with medication therapy.
Schedule a trichoscopy at Paramed — a trichologist will assess the condition of your hair and select a program: PRP, PDRN, or their combination with mesotherapy and exosomes.
