Is GFC better than PRP?

There is no strong evidence that one is clearly better. Small studies report good results with GFC, and a 2026 review of growth factor injections found improvements in density, but rated the evidence at high risk of bias. PRP has a larger, though still imperfect, body of research.

How many sessions are needed?

Both are usually given as a course of several sessions a few weeks apart, then maintenance. Studies of GFC have used about three sessions three to four weeks apart.

Do GFC or PRP work for bald areas?

No. They may help existing thinning hair but cannot create new follicles. Bald areas need a hair transplant.

Are GFC and PRP safe?

Both use your own blood, so allergic reactions are not expected. Side effects are usually mild: injection pain, tenderness, swelling or headache. Infection is rare with sterile technique.

Can I combine them with medicines?

Yes, and this is common. Minoxidil and, for men, finasteride remain the main medical treatments; injections are usually used alongside them.

GFC vs PRP for Hair Loss: Differences and Evidence

GFC vs PRP for hair loss comes down to preparation: both use your own blood, but PRP injects concentrated platelets, while GFC injects growth factors already released from them. Both may improve density in early pattern hair loss. PRP has more studies; GFC studies are small. Neither regrows bald areas. See GFC treatment.

What are GFC and PRP?

Both treatments start with a small sample of your own blood. Platelets in blood carry growth factors, proteins that help tissues repair. The idea behind both treatments is that delivering these factors to the scalp supports hair follicles that are shrinking in pattern hair loss (androgenetic alopecia).

PRP (platelet-rich plasma): the blood is spun in a centrifuge, and the plasma with a high concentration of platelets is injected. The platelets release their growth factors in the scalp.
GFC (growth factor concentrate): the blood is collected into special tubes and processed so the platelets release their growth factors before injection. The liquid injected is rich in growth factors rather than platelets.

GFC vs PRP at a glance

	GFC	PRP
Source	Your own blood	Your own blood
What is injected	Growth factors already released	Concentrated platelets
Preparation	Special tubes and processing	Centrifuge; methods vary widely
Research	Few, small studies; one recent review	More studies and reviews, still with mixed methods
Sessions	Usually several, weeks apart	Usually several, weeks apart
Downtime	Little or none	Little or none
Bald areas	Not effective	Not effective

What does the evidence say?

For PRP, systematic reviews report improvements in hair density and thickness in pattern hair loss, including in women, but studies differ in how PRP is prepared and given, and many are small. For GFC, a few small studies report improved density, and a 2026 review of growth factor injections found they appear safe and improve density and thickness, while describing its findings as hypothesis-generating because of high risk of bias.

In short, both may help some people with early thinning, results vary, and neither is a cure.

Who might suit each treatment?

Early thinning with follicles still present: either may help, alongside medicines.
People who cannot use some medicines: injections may be an option to discuss.
After a hair transplant: some doctors use injections to support existing hair.
Advanced baldness: neither helps much; see hair transplant.

What happens during a session?

A small amount of blood is taken from the arm.
It is processed into PRP or GFC.
Numbing cream or local anaesthetic is applied if needed.
The preparation is injected into thinning areas with a fine needle.
You go home the same day; mild tenderness may last a day or two.

How do injections fit with other hair-loss treatments?

For most people with pattern hair loss, medicines remain the foundation: minoxidil applied to the scalp or taken by mouth on prescription, and finasteride for men. Injections such as PRP or GFC are usually added to this, not used instead. When an area is bald or very thin, a hair transplant moves follicles that resist balding, and injections may be used alongside to support the remaining hair.

What results are realistic, and when?

People who respond usually notice less shedding first, then slightly thicker hair over three to six months. Changes are often modest and vary from person to person. Standardised photographs taken before the first session and at each review are the fairest way to judge progress. Because pattern hair loss continues, maintenance sessions are usually needed to keep any improvement.

Who should avoid these injections?

Both treatments are usually avoided in people with platelet or bleeding disorders, active scalp infection, current cancer treatment, or during pregnancy. Blood thinners and anti-inflammatory painkillers are discussed beforehand, because they can affect platelets and bruising. Hair loss from thyroid disease, iron deficiency or alopecia areata needs its own treatment first.

Myths about GFC and PRP

“One session is enough.” A course of several sessions is usual, then maintenance.
“They regrow hair on bald patches.” They cannot create new follicles.
“They replace medicines.” Medicines remain the foundation of treatment for most people.
“Results are permanent.” Pattern hair loss continues, so benefits fade without maintenance.

What should you ask before choosing?

What is causing my hair loss, and is it suitable for injections?
Which preparation do you use, and why?
How many sessions, and how will we measure the result?
What should I use alongside the injections?
