PRP — Platelet-Rich Plasma — is the most talked-about hair loss treatment in Austria in 2026. Celebrities swear by it, clinics promote it aggressively, and patients are left confused. The truth: PRP is highly effective — but only within a clearly defined window. Those treated outside that window burn through €1,500 to €3,000 with no measurable result. Here is the honest assessment from 12 years of Hair360 practice in Innsbruck.
What PRP Actually Is
Platelets (thrombocytes) are concentrated from your own blood using a centrifuge. These contain growth factors such as PDGF, VEGF and IGF-1, which can reactivate hair follicles. The concentrate is injected into the scalp — typically at 30–50 points; one session lasts 45–60 minutes.
Important: PRP is not a medication, but a biological stimulation. No active ingredient, no hormones, no side effects beyond the needle prick. That is exactly what makes it attractive — and limits its effect.
When PRP Really Helps
Three indications with proven efficacy:
1. Early androgenetic alopecia (stage I–III by Norwood). When hair is thinning but the follicles are still alive, PRP can reverse miniaturisation. Studies from 2024 (International Journal of Trichology) show a 30–40% increase in density after 4 sessions.
2. Diffuse hair loss in women (Ludwig I–II). Results here are often even better than in men, as follicle damage is usually less advanced. We see a 60% responder rate in our practice.
3. After a hair transplant as a booster. PRP 4–6 weeks after DHI transplantation accelerates graft take-up by an average of 3 weeks and reduces shock loss by 50%.
When PRP Does NOT Help
Honest truth that many clinics keep quiet about:
Complete baldness (Norwood V–VII). Once follicles have already died, PRP cannot reactivate them. Full stop. Only a hair transplant can help here.
Scarring alopecias (lichen planopilaris, frontal fibrosing alopecia). PRP cannot stop the underlying inflammation — it only temporarily masks the symptoms.
Acute telogen effluvium after stress or illness. This form usually resolves spontaneously within 6–12 months. PRP performs no better here than patience.
In active smokers or those with untreated iron/vitamin D deficiency. Growth factors require a healthy scalp microenvironment. Smokers or those with nutritional deficiencies are wasting their money.
The Right Treatment Schedule
What works (according to current evidence):
- Initial phase: 4 sessions at 4-week intervals
- Consolidation: 1 session after 3 months, 1 after 6 months
- Maintenance: a top-up every 9–12 months
Those who stop after just 2 sessions often see nothing. Those who have injections every 4 weeks for 12 months are over-treating. Both are common — and both are costly without added benefit.
Costs, Reality, Pitfalls
In Austria, one PRP session costs between €350 and €600. The full initial programme (4 sessions) comes to €1,400–€2,400. Be cautious with clinics charging under €300 per session — they often work with too low a platelet concentration (below 1 million/μl has no biological effect).
What to look out for:
Double-spin centrifugation. Single-spin procedures produce inferior plasma.
Sterile filter systems. Open procedures increase the risk of infection.
An experienced practitioner. Injection depth (1.5–2.5 mm into the dermis) is critical. Incorrect injection = no effect.
PRP or Hair Transplant — Which and When?
A rule of thumb from our clinic:
- Norwood I–II / Ludwig I: PRP is sufficient
- Norwood III / Ludwig II: PRP + minoxidil combination, possibly DHI later
- Norwood IV+: DHI hair transplantation as primary therapy, PRP as booster
- Pronounced receding hairline, mild crown thinning: targeted DHI + PRP for the crown
Anyone at Norwood IV opting for PRP treatment alone will be disappointed. Anyone at Norwood I opting for transplantation straight away is being over-treated.
Your Diagnosis Is the Starting Point
At Hair360 in Innsbruck, every consultation begins with trichoscopy (digital scalp analysis), a blood test and an honest assessment — even if that means we advise against PRP. Initial analysis appointments are free of charge.
