PRF hair treatment: how platelet-rich fibrin compares with PRP, the 2026 evidence and what to ask in Malaysia

If you have looked into PRP for thinning hair in Malaysia, you may have seen another three letters on clinic menus: PRF. It stands for platelet-rich fibrin, and it is often sold as a "second generation" version of PRP. Both come from your own blood, both are injected into the scalp, and both aim to support follicles that are shrinking but still alive. The difference lies in how the blood is processed and what ends up in the syringe.

This guide explains how PRF is made, how it is meant to work on the hair follicle, what the published studies actually show up to 2026, how it compares with PRP and other options, the risks, what a typical course looks like, and the questions worth asking a clinic in KL, Selangor, Penang, Johor Bahru or anywhere else before you pay. It is general information, not personal medical advice. If you are new to blood-based treatments, start with PRP for hair loss and come back here.

The short answer

• What it is: PRF is prepared by spinning your blood at a lower speed, usually without an added anticoagulant, so the platelets, white cells and fibrinogen stay together in a liquid that slowly turns into a soft fibrin gel ¹.
• Why clinics offer it: The fibrin network is thought to release growth factors more gradually than standard PRP, which was one of the reasons liquid PRF was developed to address the limits of PRP ¹.
• What the evidence says: Small studies report better hair density after a few monthly sessions ^{2 3 4}. A 2026 randomised trial in women with female pattern hair loss found that injectable PRF increased hair counts more than PRP after 24 weeks, with the lowest rate of side effects of the three treatments tested ⁵.
• The catch: Most PRF studies are small, short and often have no control group, and there is still no agreed recipe for preparing it, so one clinic's "PRF" may not match another's ^{1 6}.
• Where it fits: Treat PRF as a possible add-on to proven treatments such as minoxidil, not as a replacement for them and not as a fix for genetic hair loss ⁷.

How pattern hair loss works, and where platelets come in

Each hair grows from a follicle that cycles through a growth phase (anagen), a short transition (catagen) and a resting phase (telogen) before the hair sheds and a new one starts. On the scalp, anagen normally lasts years, which is why scalp hair can grow long.

In androgenetic alopecia, the common pattern hair loss in men and women, follicles on the top of the head are sensitive to dihydrotestosterone (DHT). Over many cycles, the growth phase shortens and the follicle shrinks, a process called miniaturisation. Thick, pigmented hairs are slowly replaced by thin, short, pale ones until some follicles stop producing visible hair at all. You can read more about this in DHT and pattern hair loss.

Platelets are tiny blood cells best known for clotting, but they also carry growth factors, signalling proteins such as platelet-derived growth factor (PDGF), vascular endothelial growth factor (VEGF) and transforming growth factor beta. In the lab, these signals can support cell survival, blood vessel formation and the cells at the base of the follicle. The idea behind both PRP and PRF is to concentrate these signals and deliver them to follicles that are miniaturising, in the hope of lengthening the growth phase and thickening the hair shaft.

In the 2026 randomised trial in women, higher VEGF levels in the prepared samples were linked with larger increases in hair count, which fits the theory that blood vessel signals matter ⁵. That is a correlation in one study, not proof of the mechanism, but it is a useful clue.

What platelet treatments cannot do is change your genes or block DHT. That is why guideline-backed treatments such as minoxidil and finasteride remain the foundation for pattern hair loss ⁷.

PRF versus PRP: what is actually different

Both start the same way: a nurse or doctor draws a few tubes of blood from your arm. What happens next is where they part.

PRP (platelet-rich plasma). The blood is collected in tubes that usually contain an anticoagulant so it cannot clot. It is spun in a centrifuge, often more than once, to separate the red cells from a plasma layer rich in platelets. That plasma is drawn off and injected. Some protocols add an activator such as calcium chloride.

PRF (platelet-rich fibrin). The blood is collected without an anticoagulant and spun at lower speed for a shorter time. The top layer, sometimes called liquid PRF or injectable PRF (i-PRF), contains platelets, white blood cells and fibrinogen. Because nothing stops it from clotting, it must be injected within minutes, before it sets into a soft fibrin gel. Inside the scalp, that fibrin network is thought to act like a scaffold that holds cells in place and lets growth factors seep out over a longer period ¹.

A 2024 review in the Journal of Cosmetic Dermatology looked at the preparation methods used so far. Most studies favoured low centrifuge speeds and shorter spin times, a horizontal centrifuge may give a higher platelet yield with less damage to cells than a fixed-angle one, and there is no consensus on the best method ¹. In plain terms, "PRF" is a family of recipes, not a single standard product.

You may also see related names: PRFM (platelet-rich fibrin matrix), iL-PRF (injectable leukocyte and platelet-rich fibrin), A-PRF (advanced PRF) and CGF (concentrated growth factors). They differ in spin speed, tube type and whether white cells are kept. For the growth factor concentrate approach, see GFC hair treatment.

What the studies show so far

Here is the published evidence in roughly chronological order, with what each study can and cannot tell you.

Early PRFM study (2014). Fifteen adults, nine men and six women, received three monthly injections of PRFM. Hair density rose significantly at two and three months, and the gain was close to, but not quite, statistically significant at six months. People who improved by more than a quarter at two months were more likely to keep a good result at six months ². There was no control group.

iL-PRF with a control group (2018). An Italian study gave two injections three months apart, after a minor scalp stimulation, and compared the treated group with a control group. A blinded expert panel rated photos at six months, and the treated group scored better across ages and in both sexes ⁸.

Women with female pattern hair loss (2024). A UK case series treated eleven women with three monthly i-PRF injections using a mesotherapy gun. Hair counts, volume and thickness improved at three and six months, and side effects were minor and short-lived ⁴. Eleven people is a very small group.

Hard-to-treat cases (2025). A Chinese single-centre study enrolled thirty people with androgenetic alopecia who had not responded well to conventional treatment. After six monthly i-PRF injections, 80% were rated as responders at six months, with improvements in hair scores, scalp inflammation scores and quality of life, and minimal adverse reactions ³. Again, there was no comparison group.

Head-to-head randomised trial (2026). This is the most useful study so far. Women with Sinclair grade II to III female pattern hair loss were randomly assigned to four sessions, four weeks apart, of PRP, i-PRF or CGF. Seventy-four completed the study. At 24 weeks, the increase in non-vellus hair count in the target area was about 27% for CGF, about 27% for i-PRF and about 15% for PRP. The i-PRF and CGF groups did significantly better than PRP on hair count, but hair diameter improved similarly in all three groups, and the i-PRF group had the lowest rate of side effects ⁵.

Reviews. A 2024 systematic review of injectable PRF for alopecia and facial rejuvenation found seven studies with 130 people in total, three of them on hair, and called for larger controlled studies with longer follow-up ⁹. A 2026 systematic review of regenerative treatments for androgenetic alopecia included four prospective PRF studies with 204 participants and reported hair density improvements of roughly 62% to 97% within three to six months, with mild and temporary side effects. The same review notes that the evidence base mixes trial designs and that the number of studies is still small ⁶.

How to read all this. The direction of the evidence is encouraging, and the 2026 trial suggests PRF may outperform standard PRP for some women. But most studies are small, most follow people for six months or less, and many have no control group. Nobody yet knows how long the gains last after sessions stop, or how PRF compares with minoxidil or finasteride directly.

Who might be a reasonable candidate

PRF, like PRP, works on follicles that still exist. People most likely to be considered are those with:

• Early to moderate pattern hair loss in men, such as Norwood 2 to 4.
• Female pattern hair loss, especially widening of the parting or thinning at the crown.
• Thinning that has not responded well enough to minoxidil alone, used as an add-on.
• Hair transplant patients, where some surgeons use platelet products around the procedure. A 2026 review noted added benefits when PRF was combined with transplantation ⁶.

PRF is less likely to help, or needs specialist assessment first, if you have:

• Large smooth bald areas where follicles are gone. Options there are surgical or cosmetic, such as a transplant or scalp micropigmentation.
• Hair loss with an unclear cause. Thyroid problems, iron deficiency, medicines and stress-related shedding should be ruled out first. See chronic telogen effluvium.
• Scarring alopecia or alopecia areata. There are only case reports for PRF in these conditions, and they need a dermatologist's care. See alopecia areata.

Because PRF involves a blood draw and injections, clinics commonly ask about bleeding or platelet disorders, blood-thinning medicines, active scalp infection, pregnancy, and recent illness before going ahead. Tell the doctor about every medicine and supplement you take.

What a PRF session usually involves

Protocols vary between clinics, but a typical course looks like this:

1. Assessment. A doctor examines your scalp, ideally with trichoscopy, to confirm the type of hair loss and take baseline photos. See scalp analysis and trichoscopy.
2. Blood draw. One or more small tubes are drawn from a vein in your arm.
3. Processing. The tubes are spun for a short time. Because there is no anticoagulant, the clock is running from this point.
4. Numbing. Some clinics apply numbing cream or use cooling to reduce discomfort.
5. Injection. The liquid PRF is injected into the thinning areas with fine needles or an injector gun, usually within minutes of processing.
6. Aftercare. Mild soreness, redness and small bumps are common for a day or two. Follow the clinic's advice on washing, sweating and styling.
7. Repeat. Courses in studies ranged from two sessions three months apart to six monthly sessions ^{8 3}. Maintenance sessions, if any, are decided later based on results.
8. Review. Results are usually judged at three to six months using standardised photos and hair counts. See tracking hair loss progress with photos.

Pros, cons and risks

Possible advantages

• Uses your own blood, so allergic reactions to the material itself are unlikely.
• No anticoagulant or added activator in most protocols.
• One randomised trial in women found larger hair count gains than PRP, with fewer side effects ⁵.
• Can be combined with minoxidil and other treatments.

Drawbacks

• Evidence is still thin, with few controlled trials and short follow-up ^{9 6}.
• No standard preparation, so quality depends heavily on the clinic's equipment and technique ¹.
• Needs repeated clinic visits, blood draws and injections.
• Does not address DHT, so results are likely to fade if the underlying process continues.

Risks

• Pain, tenderness and temporary swelling at injection sites.
• Bruising, pinpoint bleeding and mild headache.
• Infection if hygiene is poor, which is why a proper clinical setting matters.
• Temporary shedding in some people after injections.
• Rare complications have been reported with scalp injections of blood products in general. Read PRP side effects for a fuller list.

Timelines: what to expect month by month

• Weeks 1 to 4: Soreness settles within days. You will not see new hair yet.
• Weeks 6 to 8: Some people notice less shedding. One review of PRF in women described reduced shedding within three to four weeks and new growth from six to eight weeks ⁶.
• Months 3 to 6: This is when studies measured hair counts and density, and when you should review your own progress honestly ⁵.
• Beyond 6 months: Long-term data are lacking. Plan with your doctor how you will maintain results, usually with daily topical treatment and occasional sessions.

The Malaysian context

Climate. Malaysia's heat and humidity mean many people sweat through the day and wash their hair often. After injections, small puncture sites need a short time to close, so ask how long to wait before heavy exercise, outdoor work, helmet use or a hot shower. For general scalp care in this climate, see scalp care in humid weather.

Fasting and prayer. If you plan a session during Ramadan, ask about timing, since a blood draw while dehydrated can make you feel faint. Muslim patients who want religious guidance on treatments using their own blood should ask a qualified religious authority. For everyday questions about wet hair and the scalp, see wuduk and hair loss.

Diet. A balanced diet with enough protein and iron supports normal hair growth, and low ferritin or vitamin D should be checked and corrected before you invest in clinic treatments. See vitamin deficiencies and hair loss.

Who does it. PRF involves drawing blood and injecting the scalp, so it should be done under a registered medical practitioner in a proper clinical setting. You can ask for the doctor's full name and check their registration with the Malaysian Medical Council, and ask whether the tubes and centrifuge used are registered medical devices.

Cost. Prices for PRF in Malaysia vary widely between clinics and depend on the number of sessions and what is bundled. There is no reliable published price range, so ask for a written quote covering the full course, any blood tests and follow-up reviews. For budgeting, see hair loss treatment cost in Malaysia and PRP treatment price in Malaysia.

Where to go. Look for a clinic that diagnoses before it sells, offers PRF as part of a plan rather than a standalone package, and measures results objectively. The checklist below helps. See also how to choose a hair loss clinic.

Common myths

• "PRF is just a more expensive PRP." The preparation is genuinely different, and one randomised trial found better hair counts in women. But it is still not proven to be better for everyone ⁵.
• "Because it is my own blood, it has no risks." Injections can still cause pain, bruising, infection and shedding.
• "PRF can replace minoxidil." Studies tested it mostly in people who were also on, or had tried, standard treatments. Medicines remain the foundation ⁷.
• "One session is enough." Every study used several sessions, and none showed lasting results after a single one.
• "It works on any bald patch." It can only act on follicles that are still there.
• "All PRF is the same." Spin speed, tube type, centrifuge and timing all vary, and there is no agreed standard ¹.

A practical checklist before you book

• Get your hair loss type confirmed by a doctor, ideally with trichoscopy and blood tests if needed.
• Ask whether it is PRP, PRF, i-PRF, PRFM or CGF, and why they chose it for you.
• Ask how the blood is processed: tube type, spin speed and time, and how fast it is injected.
• Ask who performs the injection and confirm the doctor is registered.
• Ask how many sessions, how far apart, and what maintenance looks like.
• Ask how progress will be measured: standardised photos, hair counts, or both.
• Ask what to avoid after the session in Malaysian heat: sweating, helmets, washing, swimming.
• Get a written quote for the full course, with no pressure to sign a package on the day.
• Keep using any proven treatment your doctor recommends unless told otherwise.
• Set a review point at three to six months and be willing to stop if there is no clear benefit.

Key takeaways

• PRF is made from your own blood without an anticoagulant, so platelets, white cells and fibrin stay together and may release growth factors more slowly than PRP.
• Small studies and a 2026 randomised trial in women suggest it can improve hair counts, in that trial more than PRP, with mild side effects.
• Evidence is still limited: small groups, short follow-up, few controlled trials and no standard recipe.
• It works best as part of a plan with proven treatments, for follicles that are still alive.
• In Malaysia, choose a registered doctor, ask exactly how the PRF is prepared, plan aftercare around the heat, and judge results honestly at three to six months.

Frequently asked questions

Is PRF better than PRP for hair loss?

Possibly for some people, but it is not proven for everyone. A 2026 randomised trial in women with female pattern hair loss found injectable PRF raised hair counts by about 27% at 24 weeks compared with about 15% for PRP, with fewer side effects. Hair thickness improved similarly in both groups, and there are no large head-to-head trials in men yet.

How many PRF sessions are needed?

Studies used anywhere from two sessions three months apart to six monthly sessions. Many clinics plan three to four sessions about a month apart, then review results at three to six months before deciding on maintenance.

Is PRF painful?

Most people feel stinging and pressure during the injections and some tenderness afterwards. Numbing cream or cooling can help. Soreness usually settles within a day or two.

How long do PRF results last?

Nobody knows yet. Most studies followed people for six months or less. Because PRF does not block DHT, results are likely to fade if pattern hair loss continues, which is why it is usually combined with daily treatment.

Can I use minoxidil with PRF?

Yes, in most cases, and many study participants were already on standard treatments. Ask your doctor whether to pause minoxidil for a day or two around each session.

Who should not have PRF?

People with bleeding or platelet disorders, those on blood thinners, anyone with an active scalp infection, and people who are pregnant usually need to avoid it or get specialist advice first. Always tell the doctor about every medicine and supplement.

How much does PRF cost in Malaysia?

Prices vary widely between clinics and there is no reliable published range. Ask for a written quote that covers the full course, blood tests and follow-up reviews before you commit.

Is PRF the same as GFC or CGF?

No. They are related platelet-based preparations made with different tubes, spin speeds and processing steps. GFC and CGF focus on concentrated growth factors, while PRF keeps fibrin and white cells in the mix.
