PRP vs PRF for Hair Loss — Which Platelet Therapy Works Better?

Medically reviewed by Dr. Dan Xu, M.D., CCFP — CPSO Licensed Physician and Founder & Medical Director of ID Cosmetic Clinic, Markham. Last updated June 2026.

“PRP or PRF — which platelet treatment actually works better for hair loss?” is a question we hear often in our Markham clinic, and the honest answer is that they are close cousins, not rivals. Both are autologous (made from your own blood), both rely on concentrated growth factors to stimulate the hair follicle, and both are used mainly for androgenetic alopecia (genetic thinning). What separates them is how they are prepared and how their growth factors are released over time. This guide breaks down exactly how each one works, who each is best for, what to realistically expect, who should not have them, and what they cost in Toronto — so you can walk into a consultation already asking the right questions.

PRP vs PRF for hair loss — at a glance

Numbers describe typical ranges, not guarantees — individual results depend on your hair-loss type and stage. Prices vary by protocol and number of sessions; book a consultation for an exact quote. (Cost figures to be confirmed by the clinic before publishing.)

Which one is right for you?

• Choose PRP if you want the platelet therapy with the most published research and the most standardised, well-controlled preparation — a sensible default for early-to-moderate androgenetic alopecia and the option many physicians reach for first.
• Choose PRF if you prefer a completely additive-free, all-natural preparation, want growth factors released more slowly over time, or are planning a combination approach — the injectable form (i-PRF) can be mixed with exosomes in the same session.
• Either is reasonable if your thinning is early-to-moderate and your follicles are still alive — both work by stimulating existing hair, not by creating new follicles.
• Neither alone is enough if you have advanced, long-standing baldness with scarred or “dead” follicles — in that case a hair-transplant assessment or a fuller medical plan is more honest than promising regrowth from injections.

PRP for hair loss: the proven standard

PRP (platelet-rich plasma) has been used in surgery and sports medicine since the 1970s and was adapted for hair loss more than a decade ago. It is the most-studied of the two, with the most standardised preparation.

• How it works: a small sample of your blood is drawn into a tube containing an anticoagulant (so it does not clot before processing), then spun in a centrifuge — typically twice — to concentrate the platelets to several times their normal level. When this liquid is injected into the scalp, the platelets are activated and release a burst of growth factors (PDGF, VEGF, TGF-β, IGF-1 and others) that stimulate the hair-follicle “papilla” cells and improve local blood supply.
• Best for: early-to-moderate androgenetic alopecia (genetic thinning) where follicles are miniaturised but still alive; patients who want the option backed by the largest body of evidence.
• What it feels like: a quick blood draw, then a series of small injections across the scalp. Most people rate it mild — the scalp can be numbed beforehand, and the session takes roughly 30–45 minutes.
• Downtime & results: essentially none — mild tenderness, redness or pinpoint marks can last a day. Reduced shedding is often noticed first (around 6–8 weeks), with visible density building over 3–4 months. PRP is given as an initial series (commonly 3–4 sessions a few weeks apart) followed by maintenance every few months, because the growth-factor effect is concentrated and relatively short-lived.

PRF for hair loss: additive-free, slow-release

PRF (platelet-rich fibrin) was first developed in 2001 for oral and facial surgery and is increasingly used for hair restoration. It is often described as the “second generation” of platelet therapy.

• How it works: the key difference is that no anticoagulant or additive is used. Your blood is drawn and spun once at a lower speed, and because nothing stops it clotting, it forms a natural fibrin scaffold that traps platelets, white cells and growth factors. As that fibrin slowly breaks down in the scalp, growth factors are released gradually over days to weeks rather than in a single burst — which in theory matches the follicle’s biological cycle more closely. PRF also retains more white cells, which may help modulate the scalp environment.
• Best for: early-to-moderate androgenetic alopecia, telogen (stress/shedding-type) hair loss, and patients who want a fully autologous, additive-free option. The liquid version, i-PRF, is injectable like PRP; a firmer gel version (A-PRF) keeps more white cells.
• What it feels like: the same patient experience as PRP — a blood draw followed by scalp injections, with numbing available and a similar comfort level.
• Downtime & results: essentially none, with the same mild, short-lived scalp tenderness or redness. The treatment timeline mirrors PRP — an initial series then maintenance — though the slower release may, in some patients, allow maintenance intervals to stretch slightly. Note that long-term comparative data for PRF in hair loss is still growing.

This is general information, not medical advice. Whether PRP, PRF, a combination, or a different plan suits you can only be judged by a qualified physician after assessing your scalp and hair-loss pattern in person.

Can you combine PRP, PRF and other therapies?

Yes — and for many patients a combination is more effective than any single tool. A few common strategies:

• PRF + exosomes: because injectable i-PRF is additive-free and liquid, it can be mixed with an exosome solution and injected in the same session. PRF supplies your own growth-factor scaffold while exosomes add cell-signalling messengers — one of the more popular combination protocols, though large head-to-head studies are still underway.
• PRP/PRF + medical therapy: platelet injections are usually added to, not used instead of, evidence-based medical treatment. A typical androgenetic-alopecia plan layers topical minoxidil (and, for appropriate male patients, oral finasteride) with PRP or PRF, because medication maintains the follicle while platelet therapy stimulates it. Used together they generally outperform any one approach alone.
• Sequencing PRP then PRF: some clinicians start with PRP and use PRF for longer-interval maintenance. The right protocol depends on your hair-loss type, your response, and your physician’s judgement.

Who is not a good candidate?

PRP and PRF are low-risk because they use your own blood, but they are not right for everyone. You may need to wait or choose a different option if you:

• have an active scalp infection, inflammation or open wound in the treatment area;
• have a blood or bleeding disorder, a low platelet count, or abnormal platelet function — these affect both the quality of the preparation and safety;
• take anticoagulant (“blood-thinning”) medication such as warfarin or heparin — tell your physician in advance;
• have anaemia or a low haemoglobin level, which can reduce the quality of the platelet concentrate;
• have scarring (cicatricial) alopecia, where the follicle is already fibrosed — platelet therapy cannot revive a follicle that is no longer there;
• are pregnant or breastfeeding (discuss timing with your physician);
• have a current cancer, or certain chronic conditions — your physician will assess suitability individually.

This is general information, not medical advice — a qualified physician should confirm your suitability in person and diagnose the cause of your hair loss first.

What results should you realistically expect?

Neither PRP nor PRF creates new hair follicles, and neither is a cure for genetic hair loss. They work by reviving follicles that are thinning but still alive — reducing shedding, thickening existing strands, and improving overall density gradually as your scalp responds. The first sign is usually less hair on the pillow and in the shower at around 6–8 weeks, with visible density building over 3–4 months. Patients with early-to-moderate thinning and active follicles see the most rewarding change; advanced, long-standing baldness responds far less. Results are maintained — not permanent — so ongoing maintenance sessions and, usually, medical therapy are part of the plan. Honest expectations are the single biggest predictor of satisfaction, which is why we would rather refer you for a transplant assessment than oversell injections that cannot deliver.

How much do PRP and PRF cost in Toronto?

Cost depends on the therapy, the number of sessions in your initial series, and whether it is combined with other treatments. As a general guide:

(Exact ID Cosmetic Clinic pricing to be inserted before publishing.) Be cautious of prices that look far below market — for platelet therapy, an unusually low quote can mean fewer sessions, a lower platelet concentration, or a less rigorous preparation, all of which weaken the result.
