PRF vs PRP for Hair Loss: Similar Names, Different Preparations

Platelet-rich plasma (PRP) and platelet-rich fibrin (PRF) sound alike and are sometimes marketed interchangeably. They are not the same, and the evidence for each differs. Anyone being offered either at a Hair Transplant Clinic should know what they are paying for.

What PRP is

PRP is made by drawing blood and concentrating platelets in plasma. A systematic review of PRP in androgenetic alopecia examined twelve clinical studies and found that ten reported a positive effect, but only six reported statistically significant improvement in objective measures, while two found no significant improvement (Int J Mol Sci, 2020). Studies using at least three treatments showed improvement in at least one objective measure, and reported side effects were mild, such as headache, transient pain, itching, and swelling.

What PRF is

PRF is also derived from the patient’s blood but is prepared differently, producing a fibrin matrix that holds platelets and other components. A 2026 systematic review in Stem Cell Research and Therapy included four PRF studies with 204 patients and described PRF as producing the fastest and most consistent responses, with effects appearing within one to two months. One study reported density increases of 62% at twelve weeks and 97% at twenty-four weeks (Stem Cell Res Ther, 2026).

How to read those numbers

Those figures come from single studies within a heterogeneous group. The 2026 review notes that only five of its twenty studies were randomized controlled trials and that heterogeneity limits pooled conclusions (PMC13191867). A dramatic percentage from one study does not mean you should expect the same. Protocols differ in preparation, number of sessions, and measurement method.

Neither is a replacement for surgery

PRP and PRF are sometimes offered alongside transplants as adjuncts, a topic covered in our article on FUE with PRP or stem cells. They are not substitutes for moving donor hair into areas where follicles are gone, and neither is an FDA-approved treatment for hair loss in the way marketing might imply.

Questions to ask

• Is this PRP or PRF, and how is it prepared?
• How many sessions are recommended, and at what cost?
• What evidence supports this for my type of hair loss?
• What are the side effects, and what happens if there is no benefit?

Practical considerations

Both treatments typically involve a blood draw and scalp injections, and both usually require multiple sessions. Costs add up, and benefits, if any, may fade without maintenance. Because protocols vary widely, ask which centrifuge settings, activation methods, and injection techniques will be used, and whether the clinician has published or audited their outcomes. Track your progress with standardized photographs before starting, so you can judge benefit fairly. If you have a bleeding disorder, take blood thinners, or have an active scalp condition, discuss these with your doctor first. Treat claims of guaranteed regrowth as a warning sign.

Where adjuncts fit

Adjunct treatments may have a place alongside proven approaches, but they should not distract from fundamentals such as a correct diagnosis and a realistic surgical plan.

Cost transparency matters as well. Ask for the total price of a full course, not only a first session, and whether maintenance sessions are expected. A treatment that looks inexpensive per visit can become costly over a year, and the evidence for benefit should justify the commitment before you begin.

Frequently Asked Questions

Is PRF better than PRP?

One review reports faster responses with PRF, but the evidence is limited and heterogeneous. Direct head-to-head comparison is lacking.

Is it safe?

Reported side effects for PRP are mild, but individual risk depends on your health.

Does it replace finasteride or minoxidil?

Do not assume so. Discuss it with a physician.

Understand the preparation before you pay for it. Hair Transplant Clinics should be able to explain it clearly.
