PRP vs GFC vs Exosomes for Hair Fall: What Each Actually Delivers to the Follicle, and Which to Choose
PRP, GFC and exosomes are the three regenerative scalp treatments on our hair menu, and the question “which is best for hair fall?” is asked at almost every consultation. The honest answer depends on what is being delivered to the follicle, how concentrated it is, whether you can give blood, how fast you want a result and how far the thinning has gone. This comparison explains how each is made, what it actually does at the follicle, the evidence as it stands, and the way we choose between them — which is by stage of hair loss and by cause, never by price.

Side by side
| PRP | GFC | Exosomes | |
|---|---|---|---|
| What it is | Platelet-rich plasma spun from your own blood | Growth factor concentrate: growth factors released from your platelets and purified | Lab-derived extracellular vesicles carrying growth signals; not from your blood |
| Blood draw | Yes, 10–20 ml | Yes, 10–20 ml | No |
| What reaches the follicle | Platelets that release growth factors in the scalp over hours | The growth factors themselves, at higher concentration, with no cells | Vesicles with growth factors, microRNA and signalling proteins |
| Consistency | Varies with kit, protocol and your platelet count | More consistent — the platelet step is standardised | Consistent per vial; depends on the source and storage |
| Delivery | Scalp injections | Scalp injections | Microneedling and topical application, sometimes injection |
| Sessions | 4–6 monthly, then every 3–6 months | 3–4 monthly, then every 4–6 months | 3 monthly, then every 6 months |
| First visible change | 3–4 months | 2–3 months | 2–3 months |
| Price per session | ₹4,500 | ₹6,500 | ₹7,000 |
| Course total | ₹18,000–27,000 | ₹19,500–26,000 | ₹21,000 |
| Evidence | Longest track record; many trials, variable quality | Growing; built on PRP science with standardised prep | Newest; promising early studies, less long-term data |
What each one actually does at the follicle
PRP
Blood is drawn, spun in a centrifuge to concentrate the platelets, and the plasma layer is injected across the thinning scalp. Platelets, once in the tissue, degranulate and release growth factors — platelet-derived, vascular endothelial, insulin-like and others — that prolong the follicle’s growth phase, improve blood supply to the papilla and reduce the inflammation that pushes follicles into rest. The treatment is only as good as the preparation: a poor kit yields plasma with barely more platelets than whole blood, which is why PRP results vary so much between clinics.
GFC
GFC begins the same way, with your own blood, but adds a step: the platelets are activated in a controlled process so they release their growth factors, and the resulting fluid is purified of cells and debris. What is injected is a concentrated, cell-free growth factor solution — the same signals as PRP at a higher and more predictable dose, with less swelling and tenderness because there are no cells to provoke it. Fewer sessions are needed to deliver the same total signal.
Exosomes
Exosomes are nanometre-sized vesicles that cells use to send messages to each other. The exosomes used for hair are produced in a laboratory from cultured stem cells, purified and freeze-dried; nothing is drawn from you. Delivered into the scalp after microneedling, they carry growth factors, cytokines and regulatory microRNA that signal follicle cells to re-enter the growth phase and calm the inflammation around miniaturising follicles. The appeal is a consistent, needle-light treatment with no blood draw; the caution is that the evidence is younger than PRP’s and depends heavily on the quality of the source.

How we choose between them
- Cause first: thyroid, iron, vitamin D and B12 and hormonal causes are tested for before any scalp procedure. Shedding driven by a deficiency is treated by correcting it — often with the Hairfall IV programme — and no injectable will outrun an untreated cause.
- Early, diffuse thinning with a healthy scalp and a budget: PRP, four to six sessions, with the expectation of a slow, steady improvement.
- Moderate thinning, a wish for a stronger, faster result, or a previous disappointing PRP course elsewhere: GFC.
- Needle-averse, cannot or prefer not to give blood, low platelet count, or wants the fewest visits: exosomes.
- Advanced, long-standing loss with a shiny, follicle-free scalp: none of the three; a transplant opinion is the honest advice.
- Men with pattern loss: any of the three alongside the medical treatment that addresses the hormonal driver, which the doctor discusses.

Can they be combined?
Yes, and often are. A common plan is GFC or PRP injections for the follicle plus exosomes applied over microneedled scalp in alternate sessions, with the peptide scalp serum and nutrition correction at home throughout. What never changes is the sequencing: cause corrected first, scalp health addressed second, regenerative treatment third, maintenance fourth.
Realistic expectations for all three
Shedding reduces first, usually within six to eight weeks. Visible density follows over three to six months as miniaturised hairs thicken and resting follicles restart. None of the three creates hair where the follicle is gone, and all three need maintenance because the drivers of hair loss do not retire. Clients who photograph the parting under the same light every month see the change; clients who look in the mirror daily do not, and we warn everyone of that at the first session.
PRP vs GFC vs exosomes: frequently asked questions
What is the difference between PRP and GFC?
Both start with your blood. PRP injects concentrated platelets, which release growth factors in the scalp over hours. GFC activates the platelets first and injects the purified growth factors at a higher, more consistent concentration, with no cells, so fewer sessions and less tenderness.
Are exosomes better than PRP for hair?
They are different. Exosomes are lab-derived signalling vesicles with no blood draw, consistent dose and fewer sessions, but a younger evidence base. PRP has the longest track record and the most variable quality.
Which is best for hair fall?
It depends on cause and stage. PRP for early thinning on a budget, GFC for a stronger result in fewer sessions, exosomes when you want no blood draw and the fewest visits. Deficiencies are corrected before any of them.
How many sessions does each need?
PRP four to six monthly sessions, GFC three to four, exosomes three, each followed by maintenance every three to six months.
How much does each cost?
PRP ₹4,500, GFC ₹6,500 and exosomes ₹7,000 per session at AI Aesthetics. Course totals are similar: roughly ₹18,000–27,000.
Can PRP, GFC and exosomes be combined?
Yes. A common plan alternates GFC or PRP injections with exosomes over microneedled scalp, alongside home care and nutrition correction.
