PRP for Hair Loss: What It Costs, What It Does, and What to Ask a Clinic

By Dr. Susan Lin, MD | MD HAIR | La Cañada Ventures, Inc.
Published on mdhair.com — Drug-Free Hair Regrowth Series

You have a consultation booked, or a quote in your inbox, and the number on it is somewhere between two and five thousand dollars. The clinic showed you before-and-after photographs. The person at the front desk was warm and confident and used the phrase your own blood, so there's nothing foreign going in. You want it to work. You are also aware, in the back of your mind, that you have wanted several things to work already.

So you are searching for the thing nobody in that room was incentivised to tell you: whether platelet-rich plasma is real medicine or a well-marketed way to spend a lot of money on a needle.

I want to give you a straight answer, and I want to be transparent about my position while I do it. MD HAIR does not sell PRP. We have no financial interest in whether you book it or skip it. I formulate drug-free topicals and a supplement. PRP is an in-office medical procedure performed by a physician or an appropriately supervised clinician, and it sits in a completely different part of this field from anything I make.

Which is precisely why I can say the following without hedging: PRP has better published evidence than most of the things sold for hair loss, including most of the things sold drug-free. Nothing you can buy in a bottle costs what PRP costs, and nothing you can buy in a bottle does what an injected autologous biologic does. If you are weighing PRP against a serum, you are weighing two different categories of intervention, and I am not going to pretend otherwise in order to sell you the cheaper one.

What follows is the mechanism, the evidence, the field's single biggest problem, the real cost arithmetic, and the questions I would want a member of my own family to ask before handing over a card.

What PRP Actually Is, Step by Step

PRP is autologous — from you, for you. There are three stages, and understanding each one is what lets you evaluate a clinic later.

1. The draw

A phlebotomist draws blood, typically 10 to 60 mL depending on the protocol, into tubes containing an anticoagulant so the sample does not clot before processing. This is an ordinary venipuncture. It takes a few minutes.

2. The spin

The tubes go into a centrifuge. Spinning separates whole blood by density into three layers: red cells at the bottom, a thin intermediate buffy coat rich in platelets and white cells, and platelet-poor plasma on top. The operator harvests the platelet-enriched fraction.

This is the step where PRP stops being one thing. Centrifuge speed, spin duration, whether there is a single spin or a double spin, which tube system is used, and where exactly the operator draws the pipette line all change what ends up in the syringe — how concentrated the platelets are, and how many leukocytes come along. Dhurat and Sukesh's methodological review lays out how widely these preparation variables range across published protocols and commercial systems (Dhurat & Sukesh, 2014).

3. The injection

The concentrate is injected into the scalp, usually into the dermis or at the dermal–subcutaneous junction, in a grid across the thinning zone. Some clinicians activate the platelets first with calcium chloride or thrombin; others rely on collagen contact in the tissue to do it. Sessions are commonly spaced three to six weeks apart for an initial series, then maintained.

What the platelets are supposed to do once they are there

Platelets are not just clotting cells. Their alpha granules are a storage depot for growth factors, and degranulation releases them locally: platelet-derived growth factor (PDGF), vascular endothelial growth factor (VEGF), transforming growth factor-beta (TGF-β), insulin-like growth factor-1 (IGF-1), epidermal growth factor (EGF) and others.

Several of those are directly relevant to hair biology. VEGF is associated with perifollicular angiogenesis and larger follicle size in experimental work; IGF-1 supports anagen maintenance; PDGF is implicated in the induction and maintenance of the anagen phase. The proposed mechanism, then, is that a concentrated bolus of these signals delivered next to miniaturising follicles prolongs anagen, nudges resting follicles back into growth, and improves the perifollicular vascular bed (Gupta & Carviel, 2016).

That is a coherent hypothesis built on real cell biology. Note what it is not: it is not a claim that PRP addresses androgen signalling. PRP does not lower DHT and does not alter the genetic androgen sensitivity of your follicles. Like several interventions in this field, it acts on the growth environment rather than on the underlying driver — which has consequences for maintenance that I will come back to.

What the Evidence Actually Supports

Here is my honest reading of the literature, stated at the level it exists.

There are randomized, placebo- or sham-controlled trials, and several are positive. Gentile and colleagues ran a randomized placebo-controlled trial in men with androgenetic alopecia and reported significant increases in hair count and hair density in the treated half-scalp compared with control (Gentile et al., 2015). Alves and Grimalt conducted a randomized, double-blind, half-head study in men and women and likewise reported increases in hair count and density on the PRP side (Alves & Grimalt, 2016).

The half-head design is a genuine methodological strength. Each participant serves as their own control, which removes between-subject variability in genetics, hormones, nutrition and adherence — the exact variables that wreck small hair studies. When I audit evidence, split-scalp designs get credit from me. It is the same reason I will defend the design of the split-scalp study behind our own topical serums even while conceding its other limitations.

The trials are small. Most published PRP studies enroll tens of participants, not hundreds. Follow-up is usually months, not years. And systematic reviews of the field consistently reach the same two-part conclusion: the direction of effect is generally favourable, and the pooled certainty is limited by sample size and by heterogeneity (Gupta et al., 2019).

So: better evidence than rosemary oil, better evidence than almost every supplement on the shelf, and less evidence than the two medications with FDA-approved labelling for androgenetic alopecia. That is a defensible middle position, and it is where I would place PRP if you asked me to rank it.

The Central Problem: PRP Is Not One Intervention

If you take one thing from this article, take this.

When a study of atorvastatin is published, every investigator in the world knows what atorvastatin is. The molecule is defined. The dose is stated. A second team can replicate it exactly.

PRP has no such definition. Across the published literature, studies vary in:

  • Centrifugation protocol — single versus double spin, and a wide range of g-forces and durations.
  • Final platelet concentration — often expressed as a multiple of the patient's own baseline. Protocols variously target something like two-fold, three-fold, five-fold or more, and many published reports do not state the achieved concentration at all. A frequently cited working definition in the older surgical literature put therapeutic PRP at roughly a million platelets per microlitre, about four to five times baseline — but that figure comes from bone and soft-tissue grafting work, not from scalp dermatology (Marx, 2001).
  • Leukocyte content — leukocyte-rich versus leukocyte-poor preparations behave differently, and white cells bring pro-inflammatory signals along with the growth factors.
  • Activation — calcium chloride, thrombin, or none at all.
  • Injection depth and technique — intradermal, subdermal, needle gauge, volume per injection point, grid spacing.
  • Session number and interval — three sessions monthly, four sessions fortnightly, six sessions, plus maintenance at three, four or six months.

Every one of those is a variable that could plausibly change the biological result. So when a clinic tells you studies show PRP works, the correct follow-up question is: which PRP? The study that reported a benefit used a specific preparation and a specific schedule. Unless the clinic in front of you replicates it, they are not offering you the thing that was studied. They are offering you something in the same family.

This is not a reason to dismiss PRP. It is the reason the systematic reviews cannot give you a clean effect size, and it is the reason your due diligence has to be about protocol, not about the acronym.

There is a second consequence worth naming plainly: because platelet yield depends on the patient's own blood, your PRP and your friend's PRP are not the same product either. Baseline platelet count, hydration, recent NSAID use and haematocrit all affect what comes out of the spin.

The Cost, and the Part About Maintenance

Pricing in the United States commonly runs somewhere in the region of $500 to $2,000 per session depending on region and provider, with initial series of three to four sessions, so an initial course typically lands between roughly $1,500 and $5,000. It is a cosmetic procedure and is generally not covered by insurance.

Then comes the sentence that should be in bigger type on every clinic's website than it usually is: the effect is not permanent, and it does not stop your underlying hair loss.

PRP delivers a bolus of growth signal into tissue. The signal is consumed. The androgen sensitivity that was driving miniaturisation is exactly as it was the day before your first injection. So maintenance sessions — commonly every three to six months, indefinitely — are the standard expectation, and the honest way to price PRP is not $3,000 but $3,000 to start, plus a recurring annual cost for as long as you want to hold the result.

I want to be even-handed here, because this is not a criticism unique to PRP. Topical minoxidil's FDA-approved labelling instructs continued use, and states that new hair growth is generally lost within months of stopping (DailyMed). Our own products are used continuously too. Almost nothing in this field is a course of treatment you complete. But PRP's recurring cost is an order of magnitude larger, and it is the variable most often left vague in a consultation.

Who Should Get Bloodwork Before They Get PRP

This is the part of the article I feel most strongly about, and it costs a clinic money to say it, which is presumably why they rarely do.

PRP is a stimulus. A stimulus is only useful if the follicle has the raw materials to respond with. If you are shedding because of iron deficiency, thyroid dysfunction, a recent illness or surgery, rapid weight loss, or a new medication, then injecting growth factors into your scalp addresses none of it — and you will have spent thousands of dollars on a procedure aimed at the wrong diagnosis.

Before you book, ask your own physician for:

  • A full thyroid panel — TSH plus free T4, and free T3 and antibodies where clinically indicated.
  • Serum ferritin. Not just haemoglobin. Ferritin can be low with a normal blood count, and the hair-relevant threshold discussed in the dermatology literature sits well above the bottom of most lab reference ranges (Trost et al., 2006).
  • Vitamin D, and a complete blood count.
  • Androgen studies where the clinical picture suggests it — irregular cycles, acne, hirsutism.

And a specific timing point: if your shedding began abruptly two to four months after an identifiable trigger, that pattern suggests acute telogen effluvium, which typically recovers on its own. Undergoing an expensive procedure during a spontaneous recovery is the single most reliable way to become a testimonial for something that did not cause your result.

There are also people for whom PRP is not appropriate at all, and a competent clinic will screen for them: anyone on anticoagulant or antiplatelet therapy, people with platelet disorders or thrombocytopenia, active scalp infection, certain haematological and malignant conditions, and anyone whose alopecia is scarring rather than patterned. That last one matters — in cicatricial alopecia the follicle is being destroyed and replaced with fibrous tissue, and growth factors injected into scar do not rebuild a follicle that no longer exists.

The Questions to Ask a Clinic

Print these. A good clinic will answer every one without defensiveness, and the answers themselves are diagnostic of how the practice thinks.

1. What is your exact preparation protocol? Which system or tube, single or double spin, at what speed, for how long. If nobody in the room knows, that tells you the answer is whatever the rep set up.

2. What platelet concentration do you achieve, and do you measure it? The gold-standard answer is that they run a platelet count on the concentrate, at least periodically, and can tell you the multiple over your baseline. Many clinics do not measure at all. That is common — but you should know it, because it means nobody can confirm you received a therapeutic preparation.

3. Leukocyte-rich or leukocyte-poor, and why did you choose that? You are not testing them on trivia. You are checking whether the protocol was reasoned or inherited.

4. How many sessions before we assess, and how will we assess? The right answer involves a defined number of sessions and a defined date, not you'll start noticing.

5. What is your photography standard? This is my favourite question, because it separates clinical practice from sales. Ask: fixed camera-to-scalp distance, standardized lighting, identical head positioning, same parting, dry hair, and the same intervals every time — with a global photograph plus a close-up of a marked target area. If the answer is we take a picture with the iPad, you will have no defensible way to judge your own outcome, and neither will they. Ask whether you may have copies of your baseline images. The answer should be yes, immediately.

6. Who performs the injection? Physician, PA, NP, RN — and under what supervision, per your state's regulations.

7. What does maintenance cost per year, indefinitely? Get the recurring number, not the headline number.

8. What will you do if it does not work? A serious clinician has a plan for the non-responder that is not simply more sessions.

9. Have you evaluated why I am losing hair? If a clinic will inject your scalp without asking about your thyroid, your ferritin, your medications, your recent surgeries or your family history, you are not in a clinic. You are at a counter.

The Bottom Line

PRP is a legitimate procedure with real, randomized, sham- and half-head-controlled evidence behind it — better evidence than most of the drug-free category, including mine. Its mechanism is biologically coherent: a concentrated bolus of platelet-derived growth factors delivered directly to the perifollicular tissue.

Its central weakness is not fraud; it is standardisation. There is no defined PRP, so the literature cannot give you a reliable effect size and a clinic's results depend on a protocol you have to ask about explicitly. Its second weakness is that it treats the environment rather than the driver, so the benefit requires indefinite, expensive maintenance. And its most common failure mode in practice is being performed on someone whose hair loss had a correctable medical cause nobody looked for.

Get the labs. Correct what is correctable. Then, if you have stable pattern hair loss, the budget for maintenance and a clinic that can answer the nine questions above, PRP is a reasonable thing to spend money on. That is not a sentence a hair-serum company is supposed to write. It is the true one.

Dr. Susan Lin's Clinical Perspective

"I get asked why I write favourably about a procedure I do not sell and cannot compete with on mechanism. The answer is that patients deserve the map, not the part of it I happen to own. PRP puts a concentrated growth-factor signal into scalp tissue; a topical cosmetic cannot do that, and I will not imply otherwise. What I ask patients to do is sequence it properly. I have seen too many people spend four thousand dollars on injections with a ferritin of 19 and a thyroid nobody checked, then conclude that nothing works. Nothing worked because the follicle had no substrate to build with. Correct the deficiencies, establish a stable scalp environment, then decide about the procedure — and interrogate the protocol, because PRP names a category, not a treatment."

Mechanism Spotlight: Why Platelet Concentration Is the Variable That Decides Everything

A platelet is a small anucleate cell fragment carrying, in its alpha granules, a pre-packaged library of growth factors — PDGF, VEGF, TGF-β, IGF-1, EGF. In ordinary haemostasis these are released at a wound to recruit repair. PRP is an attempt to borrow that release and aim it at a follicle.

The critical point is that this is a dose-dependent biological signal, not a switch. Too little concentration and the injected bolus is not meaningfully different from the plasma already perfusing the tissue; the growth-factor load never rises above background and nothing happens. There is also reason for caution at the other end — laboratory work in several tissues has reported that supraphysiological platelet or TGF-β concentrations can be inhibitory rather than stimulatory, so more is not automatically better (Gupta & Carviel, 2016).

That is why centrifuge protocol is not a technical footnote. Spin speed and duration determine the platelet yield; the harvest line determines leukocyte content; both determine the actual dose your follicles receive. Two clinics using the same word can deliver preparations differing several-fold in platelet concentration — and the published trials that reported benefit each used one specific point in that range (Dhurat & Sukesh, 2014). When a systematic review reports heterogeneity as the limiting factor in PRP research, this is the concrete thing it means (Gupta et al., 2019). It is also why what concentration do you achieve, and do you measure it? is the single most informative question you can ask a clinic.
