Platelet-Rich Plasma (PRP): What It Is and How It Helps

Platelet-rich plasma (PRP) is a concentrate of your own blood platelets that clinicians inject or apply to a target area to support healing. Medical teams spin a small blood sample to separate platelets and then use that platelet-rich portion where extra growth factors might speed tissue repair. People use PRP for joint pain, tendon injuries, hair thinning, and skin rejuvenation. Results depend on the condition treated, the PRP method, and the provider’s skill.

What to expect during a PRP session

First, the clinic takes a blood sample—usually a few tubes. They process it in a centrifuge for 10–15 minutes, then draw out the platelet-rich layer. The provider cleans the treatment area and injects or applies the PRP. For hair, they inject PRP into the scalp; for knee pain, they inject around the joint. Sessions take 30–60 minutes including prep. Mild soreness, swelling, or bruising at the site is common for a few days. Most people return to normal activity within 24–48 hours, but your provider may suggest avoiding heavy exercise for a short time.

How many sessions do you need? That varies: hair and skin treatments often use 3 sessions spaced 4–6 weeks apart, then maintenance once or twice a year. For tendon or joint problems, 1–3 injections may be recommended. Pay attention to realistic timelines: meaningful improvement often appears after several weeks to months.

How to pick a clinic and questions to ask

Ask who performs the procedure and how often they do it. Request details on their PRP protocol: blood volume, centrifuge type, and whether they use single- or double-spin methods. Ask for before-and-after photos for the specific condition you want treated and for patient references if possible. Check credentials—clinics run by experienced physicians or physiotherapists usually follow clearer medical protocols than spa-style outlets.

Costs vary a lot by location and indication. Expect anywhere from $200 to $2,000 per session depending on the clinic and treatment area. Insurance rarely covers PRP unless it’s part of an approved medical plan; double-check with your insurer.

Who should avoid PRP? Active infection at the treatment site, certain blood disorders, and use of strong blood thinners can make PRP unsafe. If you have questions about interactions with medications or medical conditions, bring your records and ask the provider to review them before treatment.

What does the evidence say? For some uses—like chronic tendon injuries and certain cases of knee osteoarthritis—randomized trials have shown benefit over placebo or standard care. For cosmetic uses and hair loss, results are promising but variable. Ask your provider about realistic success rates for your specific problem.

Final tip: prioritize providers who explain risks, show outcome data, and offer a clear follow-up plan. PRP can help, but the difference between a decent and a great result often comes down to technique and good patient selection.
