PRP (platelet-rich plasma) and GFC (growth factor concentrate) are both injections made from your own blood and placed in the scalp to support thinning hair. The practical difference is preparation: PRP concentrates platelets in plasma, while GFC is usually described as a kit-processed concentrate of the growth factors released by activated platelets. Head-to-head evidence is limited, so neither can honestly be called universally better.
Patients in Jaipur and across India now see both terms on clinic menus, often alongside confident claims that one outperforms the other. This guide separates what is established from what is marketing, so you can ask better questions at a consultation.
How PRP works for hair loss
PRP is made by drawing a small amount of blood, spinning it in a centrifuge and collecting the platelet-rich layer. Platelets store growth factors, including platelet-derived growth factor, vascular endothelial growth factor, epidermal growth factor and insulin-like growth factor 1. The working theory is that these signals improve blood supply around the follicle and help it stay in its active growth phase.
PRP is used mainly for androgenetic alopecia, the genetic pattern of thinning that affects both men and women. It aims to support follicles that are shrinking but still alive. It cannot create follicles where none remain. Our guide to androgenetic alopecia, its causes and treatment explains the condition in more detail.
What GFC means, and why the term is confusing
In India, GFC is largely a clinic and product term rather than a standardised medical definition. In a 2024 case series published in Cureus by a Jaipur team, GFC was prepared with a proprietary kit. About 20 to 25 ml of blood was divided into four tubes containing a platelet-activating solution, left to stand for roughly 30 minutes and centrifuged. The resulting concentrate was then injected into the scalp. Clinic literature describes this as a preparation with fewer blood cells and a higher share of growth factors than conventional PRP, and some pages call it acellular. The same pages often claim that GFC works faster, hurts less and needs fewer sessions. None of these claims was backed by a controlled comparison in the research reviewed for this article.
Two cautions apply. First, activated PRP also releases growth factors, so the line between the two products is thinner than marketing suggests. Second, some studies use a similar term, concentrated growth factor (CGF), and describe it as containing platelets, white cells and stem cell markers as well as growth factors. The abbreviations are sometimes used loosely, so two clinics offering “GFC” may not be offering the same product. Ask which kit and protocol is used.
What a session usually involves
Both treatments follow a similar pattern:
- A scalp assessment and review of your medical history.
- A blood draw, with published and clinic sources describing roughly 20 to 60 ml.
- Processing in a centrifuge, with GFC adding a platelet-activation step in the tube.
- Small injections across the thinning areas, often after local anaesthetic.
- A planned series of follow-up sessions, usually weeks apart.
GFC vs PRP compared
| Feature | PRP | GFC |
|---|---|---|
| What is injected | Platelets concentrated in plasma | Growth-factor concentrate from activated platelets, often kit-based |
| Preparation | Centrifugation, with protocols that differ between clinics and devices | Tube-based activation and centrifugation, as described in Indian reports |
| Sessions in published reports | Commonly three to six, spaced weeks apart | Four sessions over eight weeks in one small series; three sessions in another |
| Strength of evidence | Several randomised trials with mixed results | Small case series and retrospective studies, few controlled comparisons |
| Main limitation | Non-standard protocols and a placebo response in trials | Unclear terminology and unproven advantage over PRP |
Why the right choice varies between patients: the cause and stage of hair loss, how many active follicles remain, your general health and your tolerance for repeated visits all shape the decision. Someone with early thinning who wants a low-downtime option may reasonably discuss either treatment. Someone with advanced baldness may gain more from a surgical plan, and some patients use injections alongside medication or after a transplant to support the treated area. A clinician who examines your scalp can weigh these factors far better than a headline comparison can.
What the research actually shows
Evidence for PRP
The best-known controlled trial is a randomised split-scalp study from New York University, published in the Journal of the American Academy of Dermatology in 2020, with 35 participants. After three monthly sessions, hair density in PRP-treated areas rose by about 20 hairs per square centimetre. The saline-treated areas also improved, and the difference between the two sides was not statistically significant. The trial was funded by a PRP device manufacturer. More recent reviews describe generally positive findings but note inconsistent results, because preparation methods, session numbers, intervals and follow-up periods differ between studies.
Evidence for GFC and CGF
The Jaipur case series followed five men aged 22 to 29 for eight weeks, with no control group, and reported improved density and negative hair pull tests. A 20-patient split-scalp study reported that PRP combined with concentrated growth factor outperformed PRP alone. A single-centre retrospective review, summarised by Dermatology Times in 2024, reported improved hair growth six months after three CGF sessions.
These findings are encouraging, but the studies are small, short, mostly uncontrolled and sometimes combine growth factors with other treatments such as microneedling. They cannot establish that GFC beats PRP. Claims that GFC is clearly “more advanced” or gives results in fewer sessions currently rest on weaker evidence than clinic marketing implies.
Who may be a suitable candidate
Growth factor injections are generally discussed for early to moderate pattern thinning, where follicles are still active. People with long-standing smooth bald areas are more often considered for a hair transplant in Jaipur, because injections cannot restore follicles that are already gone. A specialist should also look for other causes, such as autoimmune or nutritional problems, before recommending any procedure.
Treatment is usually postponed or avoided in some situations. The clinic’s PRP information lists cancer, immunosuppressive illness, chronic liver disease, platelet abnormalities, active scalp infection and pregnancy-related issues, and its PRP guide also names blood-thinning medication. Because both treatments begin with a blood draw, similar screening is generally expected for GFC.
Side effects and safety
Both preparations use your own blood, so a reaction to the material itself is unlikely, but neither is risk free. Short-lived swelling, redness, tenderness and mild pain at the injection sites are the effects most often described. Infection, nerve irritation and scarring are rare and are linked to non-sterile technique. The Jaipur GFC series reported no infection, redness or itching, but five patients say little about rarer events.
Be cautious of any provider who calls either treatment completely safe or promises permanent results. Neither is a permanent fix, and maintenance sessions are often discussed.
What affects cost and number of sessions
Neither treatment has a fixed price. Cost depends on the kit or device, the size of the treated area, the number of sessions and whether maintenance is advised. Because protocols differ, ask for an itemised quote that states the kit used, the planned sessions and any follow-up visits, so you can compare clinics on equal terms.
Questions to ask before you choose
- Which exact kit and protocol do you use, and is it GFC, CGF or activated PRP?
- What is my diagnosis, and would medication such as minoxidil or finasteride be a sensible first step or an addition?
- How many sessions, at what interval, and how will progress be measured, for example with trichoscopy photographs?
- Do any of my medicines or health conditions make treatment unsuitable?
- What is the plan if I see no change after the agreed course?
Speaking with a specialist in Jaipur
Choosing between two similar-sounding injections matters less than confirming the cause of your hair loss.

Frequently asked questions
Is GFC better than PRP for hair loss?
Not proven. GFC is often marketed as more advanced, but published evidence consists mainly of small, mostly uncontrolled studies, with few direct comparisons against PRP. Results vary between individuals, so a specialist should judge which option suits your hair loss pattern.
What is the difference between GFC and PRP?
PRP concentrates platelets in plasma. GFC is usually described as a concentrate of growth factors released from activated platelets, often prepared with a kit. Terminology varies between clinics, so ask exactly which preparation and protocol will be used.
How many sessions of PRP or GFC are needed?
Published schedules vary. Reports describe about three to six sessions spaced weeks apart, and one small GFC series used four sessions over eight weeks. Your clinician should set the plan after examining your scalp.
Are PRP and GFC safe?
Both use your own blood, and common effects are short-lived swelling, redness and tenderness. Infection or scarring is rare but possible, particularly with poor technique. Screening for blood disorders, infections and certain medicines matters before treatment.
Can either treatment regrow hair on a completely bald area?
No. These injections aim to support follicles that are weakened but still active. Areas without living follicles are generally considered for surgical options instead.
