Book a hair transplant almost anywhere and, at some point, someone will offer you PRP. Sometimes it is pitched as a booster injected on surgery day, sometimes as a package of sessions over the following months, and sometimes as the thing that "guarantees" your grafts take. The price can add several hundred dollars, or more, to the bill.
So it is a fair question: does platelet-rich plasma actually make a transplant grow better, or is it an upsell? The honest answer sits in between. There is some evidence that it helps, the studies are small, and the size of the benefit is far smaller than the way it is often sold. This guide explains what PRP does around a transplant, what the controlled studies found, and how to decide whether it is worth it for you.
Quick answer: PRP (platelet-rich plasma, made from your own blood) is used around a hair transplant in three ways: as a storage solution for grafts while they are out of the body, injected into the recipient area during surgery, and as injections in the months after. A handful of small controlled studies, summarized in a 2025 systematic review of three trials (217 patients), found better graft survival, earlier growth and somewhat higher density with PRP, but the studies used different methods, were not standardized, and at least one report found no benefit. PRP is an optional add-on, not a requirement. What decides how well grafts grow is still the surgery itself: careful extraction, short time out of the body, gentle placement and good aftercare. Medical therapy for the hair you have not transplanted matters more over the long term than PRP does.
What PRP is, in one paragraph
PRP is a concentrate of your own platelets. A tube of blood is drawn, spun in a centrifuge to separate the layers, and the platelet-rich portion of the plasma is collected. Platelets carry growth factors that play a role in wound healing, and the theory is that delivering more of them to the scalp helps follicles recover from the stress of being moved and supports the hair that is still there. Because it comes from your own blood, allergic reactions are not expected, but there is no single standard recipe: every clinic, kit and centrifuge produces a slightly different product. That variability is one of the main reasons the research is hard to read. For how PRP compares with medical therapy and mesotherapy when there is no surgery involved, see our guide on mesotherapy vs PRP vs hair transplant.
The three ways PRP is used around a transplant
| How it's used | When | What it's meant to do | What the evidence looks like |
|---|---|---|---|
| Graft storage solution | During surgery, while grafts wait to be placed | Keep grafts healthier during their time out of the body | One small randomized study (30 patients) reported better uptake and thickness at 1 year vs saline |
| Injected into the recipient area | During surgery, after the incisions are made | Support graft survival and healing, reduce early shedding | Small controlled studies (20 and 40 patients) reported higher density and faster growth; methods differed |
| Scalp injections after surgery | Typically in the weeks and months after | Support growth of transplanted hair and thinning native hair | Mostly borrowed from PRP studies in hair loss without surgery: modest density gains, low-quality evidence |
The first two are surgery-day uses. The third is closer to standard PRP treatment for hair loss, just timed after a transplant.
What the controlled studies actually found
These are the studies most often cited for PRP with a transplant. Each was checked against PubMed; the full references are at the end.
- Uebel and colleagues, 2006. In 20 men, grafts in scalp areas treated with platelet growth factors yielded 18.7 follicular units per cm² compared with 16.4 in control areas, roughly 15% more. The gain varied enormously between patients, from about 3% to 52%.
- Garg, 2016. A randomized, single-blind study of 40 FUE patients compared PRP injected into the recipient area during surgery with saline. The PRP group showed earlier growth, less early shedding of the transplanted hairs and faster settling of redness. All 20 PRP patients had more than 75% regrowth at six months, compared with 4 of 20 in the saline group.
- Abdelkader and colleagues, 2020. In a randomized study of 30 patients, grafts stored in PRP before implantation had better uptake and thicker hair at one year than grafts stored in saline.
- Graf Guimarães and colleagues, 2020. A short report from Brazil, published as a letter, was titled plainly: PRP combined with hair transplants for androgenetic alopecia "showed no benefits".
- Xue and colleagues, 2025. In 30 patients with androgenetic alopecia who were all on medical therapy, adding PRP to FUE improved follicle survival, growth rate and hair strength compared with medication alone.
- Sindhusen and colleagues, 2025. A systematic review found only three controlled prospective trials (217 patients) of PRP as an adjunct to transplantation. All pointed in a favourable direction, but the authors stressed that PRP preparation, protocols and outcome measures differed, none used standardized evaluation, and better trials with long-term follow-up are needed.
How to read this
Put together, the research suggests PRP may help a transplant along, most consistently in the early months: less early shedding, earlier visible growth and quicker recovery of the skin. Whether it changes the final result at 12 to 18 months, and by how much, is less certain. The studies are small, mostly from single clinics, not blinded in the same way, and nobody agrees on the dose or the number of sessions.
That is not nothing. It is also a long way from the "doubles your density" or "guarantees graft survival" language that sometimes appears in sales material. If a clinic tells you a transplant will not work without PRP, that claim is not supported by the evidence.
What PRP cannot do
It helps to be clear about the limits, because this is where expectations go wrong.
- It does not create new follicles. A transplant moves existing follicles from the donor area. PRP cannot add hair to a bald area where no follicles remain, and it cannot make a 2,000-graft transplant look like 3,000.
- It does not rescue a poorly done surgery. Graft survival depends mostly on handling: how cleanly grafts are extracted, how long they are out of the body, whether they dry out, and how gently they are placed. No injection makes up for grafts that were crushed or left on a tray for hours.
- It does not stop the underlying hair loss. If your native hair keeps thinning around the transplant, the result can look patchy over the years. That is a job for medical therapy, such as finasteride or minoxidil, prescribed by a physician. PRP studies in hair loss without surgery show modest density gains at best, and the effect fades when treatment stops.
- It does not prevent normal shedding. Most transplanted hairs shed between weeks two and six, and growth starts around month three or four. Our recovery timeline explains each stage. Some studies suggest PRP reduces early shedding, but you should still expect an "ugly duckling" phase.
Is it safe?
Because PRP is made from your own blood, the main risks are the ones that come with any injection: pain or discomfort at the injection site, temporary swelling, minor bruising, and, rarely, infection if hygiene is poor. Meta-analyses of PRP for hair loss have not reported serious adverse events. People with certain blood disorders, low platelet counts, active infections, or who are on some blood-thinning medication may not be suitable, which is one reason PRP should be decided by a physician who knows your history, not added at the front desk.
Who it may make sense for
PRP is an option worth discussing, not a default. It may be more reasonable when:
- You are also losing native hair around the transplanted area and want to support it alongside medical therapy.
- You want to give a larger or denser session every possible advantage, and you are comfortable paying for a modest, uncertain benefit.
- You have healed slowly before and your physician thinks faster skin recovery is worth it.
It makes less sense when:
- You are not willing or able to take medical therapy. PRP is a weaker tool for protecting native hair than medication, and it is not a substitute for it.
- Budget is tight. Money spent on PRP would usually do more good spent on a properly planned graft count and on medication for the first year.
- You are being told it is mandatory. If you are being pushed, step back and ask why.
Questions to ask a clinic that offers PRP with your transplant
- How is the PRP prepared, and how concentrated is it compared with blood?
- Is it used in the graft storage solution, injected during surgery, or as sessions afterwards?
- How many sessions do you recommend after surgery, at what interval, and what does each one cost?
- What specific result do you expect it to change, and how will you measure that at 12 months?
- Is the transplant price the same with or without PRP, and is PRP itemized in writing?
A clinic that answers these clearly is giving you a real choice. A clinic that cannot say what PRP is meant to achieve is selling a line item.
What we do
At Colombia Care our standard price is published: US$1.40 per graft for FUE or DHI, the same for beard work, $1.50 for women's cases and $1.70 for afro-textured hair. PRP is not part of that per-graft price, and we do not add it to a plan by default. If you are curious about it, raise it in your consultation and your physician will tell you honestly whether it is likely to make a difference in your case. The full list of what the price includes is on our hair transplant cost page, and the techniques we use are explained on our hair transplant procedures page.
The bottom line
PRP around a hair transplant is a reasonable add-on with some supportive, small-scale evidence, mainly for earlier growth and less early shedding. It is not essential, its effect on the final result is uncertain, and it does not replace the things that decide how a transplant turns out: a well-planned graft count, careful surgery, good aftercare and medical therapy to protect the hair you still have.
