GFC vs PRP vs PRF for Hair Loss: What Actually Differs and Which Suits You (2026)

What is the difference between GFC, PRP and PRF?

All three treatments start the same way: a small sample of your own blood is drawn, prepared, and injected back into the scalp. What differs is what ends up in the syringe, and that difference shapes what the evidence can and cannot yet say about each one. This guide is from The Wellness Team at The London PRP Clinic by The Wellness, a doctor-led clinic in Marylebone and Canary Wharf. Every treatment we offer is performed by a GMC-registered doctor after a diagnostic assessment. Not sure which treatment fits your hair loss?

How is each treatment made?

PRP (platelet-rich plasma). Your blood is drawn into a tube with an anticoagulant and spun so the platelets become concentrated in plasma. Intact platelets are injected, and they release their growth factors once they are in the scalp. PRP is the original and most studied of the three. PRF (platelet-rich fibrin). Preparation varies by protocol, but typically the blood is spun slowly with no anticoagulant, forming a soft fibrin matrix that holds the platelets and white blood cells. The matrix is designed to release growth factors gradually over several days. GFC (growth factor concentrate). Preparation varies by kit and protocol. In the 2026 randomised trial below, the specific preparation used in the cited 44-adult trial works like this: your blood is drawn into a purpose-built kit tube containing a platelet-activating solution, the platelets release their growth factors inside the tube during a short activation period, and a spin then separates out the cells. The kit is designed to produce a clear, cell-free serum of concentrated growth factors, including EGF, PDGF, IGF-1 and VEGF. The simplest way to think about it: PRP and PRF deliver the platelets. GFC is designed to deliver what the platelets release.

What does the evidence say?

PRP has the deepest evidence base of the three: a 2025 review of 43 randomised controlled trials covering 1,877 participants found it significantly increases hair density (Anitua and colleagues, Dermatology and Therapy). GFC is newer, and the honest position is that its evidence is promising but early:

• In a 2026 randomised, assessor-blinded trial of 44 adults with pattern hair loss (Choubey and colleagues, Journal of Cutaneous and Aesthetic Surgery), three monthly GFC sessions were compared with three monthly PRP sessions, with everyone also using minoxidil. Hair improvements were seen in both groups (a 38.7% improvement in the terminal-to-vellus hair ratio with GFC against 40.8% with PRP), and the difference between the groups was not statistically significant: the trial cannot tell us which treatment works better, and a single 44-patient trial cannot settle the question. Pain scores were significantly lower with GFC (a median of 2 out of 10 against 6 out of 10) and satisfaction was higher (8 out of 10 against 6 out of 10). Because everyone used minoxidil, the trial shows GFC working alongside it rather than proving a standalone effect.
• A 2026 retrospective comparative study of 42 patients (Garg and Thirumalaiswamy, Dermatologic Surgery) found GFC improved hair counts earlier, while PRP's benefit held up better at six months. The authors suggest the two could be combined in sequence, although that exact sequence has not been tested in a trial. As a retrospective study, it shows associations rather than proving causes.
• A 2024 five-patient pilot study (Bhargava and colleagues, Cureus) reported improved hair density and no injection-site infection, redness or itching. With only five patients and no control group, it cannot establish how well or how safely GFC works in general.
• A 2026 systematic review and meta-analysis (Alali and colleagues, Aesthetic Plastic Surgery; 12 studies, 745 patients) found growth factor injections improved hair density, thickness and patient satisfaction over 12 months. The authors rated the included evidence at high risk of bias, so the findings should be treated as early-stage. No large trial has shown GFC to be superior to PRP, and we do not claim it is. What the current evidence supports is that GFC is a legitimate option with encouraging early results, particularly on comfort - not that it matches or beats PRP on regrowth.

Which treatment is right for me?

There is no honest universal answer, and we will not invent one. The right choice depends on your diagnosis, your stage of hair loss and how you have responded to treatment before. Published GFC studies have involved mainly people with early to moderate pattern hair loss, where follicles are still active. None of these treatments can regrow hair where follicles have been permanently lost, and none replaces medical treatment for the underlying cause of hair loss where one is needed. That is why every patient here starts with a consultation and diagnostic assessment, which can include trichoscopy and blood tests where indicated, before any treatment is recommended.

How much do GFC, PRP and PRF cost?

For context, our published PRP pricing as of October 2026 is £450 per session, or £1,215 for a course of three. GFC is not currently available for booking. Most published protocols use three sessions, spaced about four weeks apart, with a review to assess response.

Frequently asked questions

Is GFC better than PRP? Current evidence does not show GFC to be superior. In the 44-adult trial discussed above, both groups improved and the difference between them was not statistically significant, while GFC caused significantly less pain. That was one 44-adult trial in which everyone also used minoxidil, so it cannot settle the question. Can I combine GFC with PRP or PRF? One research group has suggested combining GFC and PRP in sequence, but that approach has not been tested in a trial of its own. Whether any combination makes sense for you is a question for a doctor after assessment. How many GFC sessions will I need? Most published protocols used three sessions about four weeks apart, with a review of response before any further course. Is GFC safe? GFC uses your own blood, prepared in a single-use kit. In the published studies, reported side effects were mild and short-lived, such as injection-site soreness or redness. Those small studies are not a full risk assessment: they cannot capture less common risks of blood draws and scalp injections, such as bruising, bleeding or infection. A medical assessment comes first to check suitability. When will I see results? Hair cycling is slow. In the studies above, results were measured between eight weeks and twelve months after starting treatment.
