Does GFC Hurt? Pain, Downtime and What Treatment Actually Feels Like (2026)

Does GFC hurt?

In a 2026 randomised trial comparing GFC with PRP for hair loss, patients rated GFC at a median of 2 out of 10 for pain, against 6 out of 10 for PRP - a statistically significant difference. That was one trial of 44 adults in which everyone also used minoxidil, so it is encouraging rather than definitive. The injections use very fine needles, and the scalp can be numbed with a topical anaesthetic beforehand. 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 is performed by a GMC-registered doctor. GFC is not currently available for booking; this guide explains the published evidence so you can discuss it properly at a consultation. Worried about discomfort?

What does the evidence say about GFC and pain?

The clearest data comes from a 2026 randomised, assessor-blinded trial of 44 adults with pattern hair loss (Choubey and colleagues, Journal of Cutaneous and Aesthetic Surgery). Patients received three monthly sessions of either GFC or PRP, with everyone also using minoxidil. The median pain score was 2 out of 10 for GFC against 6 out of 10 for PRP, a statistically significant difference, and satisfaction scores were higher in the GFC group (8 out of 10 against 6 out of 10). No serious adverse effects were reported in either group. That is one trial of 44 people, so we present it as encouraging rather than definitive. The trial was not designed to explain why pain scores differed, so we do not claim a reason.

What does GFC treatment involve?

Protocols vary by kit. The specific preparation used in the cited 44-adult 2026 trial follows these steps:

• Blood draw. A small sample of blood is taken from your arm, similar to a routine blood test.
• Activation. The blood rests in the GFC kit tube while the platelets release their growth factors into the plasma - around 30 minutes in the studied protocols.
• Centrifugation. The tube is spun to separate the growth factor serum from the blood cells.
• Preparation. The serum is drawn into a fine syringe, and the scalp is cleaned and can be numbed with a topical anaesthetic.
• Injection. The serum is injected across the areas of thinning with a fine needle. Exact timings, session length and aftercare are confirmed by the treating clinician for each patient.

What is the downtime after GFC?

The published studies do not set out formal recovery protocols. Reported side effects were mild and short-lived, such as injection-site soreness or redness. These small studies are not a full risk assessment. Your clinician will give you specific aftercare instructions for any treatment you have.

Who should not have GFC?

Suitability for any autologous blood treatment is a medical decision, not a checklist. A doctor will review your medical history, any medication you take and the cause of your hair loss before recommending anything. Book a consultation via WhatsApp or see all our hair treatments.

Frequently asked questions

Is GFC less painful than PRP? In the 2026 trial above, patients reported less pain with GFC: a median of 2 out of 10 against 6 out of 10. That is one trial, and individual experience varies. Can I go back to work after GFC? The studies do not report time off work. Reported side effects were mild, and your clinician will advise you based on your own treatment. Does the blood draw hurt? It feels similar to any routine blood test: a brief scratch as the needle goes in. How many sessions will I need? Most published protocols used three sessions about four weeks apart, with a review of response before further treatment. What if I am nervous about needles? Tell the clinic when you book, so the team can allow time to talk you through each step before anything happens.
