- PRF uses components from your own blood to deliver growth factors to hair follicles. Exosomes are derived from stem cells and are not autologous, but they carry a concentrated payload of signalling molecules that may support follicle activity in some patients.
- The core difference is the source material. PRF is autologous, which reduces the risk of adverse reaction. Exosomes are acellular and contain no live cells, which also reduces rejection risk but through a different mechanism.
- The evidence base for PRF is more established, building on years of PRP research. Exosome therapy is newer and its evidence base is still developing, though clinical interest is growing.
- Which option is more appropriate depends on your platelet health, the specific concern being treated, and your treatment history. A consultation with a qualified practitioner is the right way to assess this.
Both PRF and exosome treatments are hair loss treatments available at Hair and Skin Science, and patients researching hair restoration frequently encounter both without a clear explanation of how they differ. This guide covers what each treatment is, where the evidence sits, and what factors determine which is more appropriate for a given patient.
What do PRF and exosomes have in common?
Both treatments work by delivering biological signals to hair follicles to support growth, and that shared principle is where the similarity largely ends.
PRF (Platelet-Rich Fibrin) is derived from your own blood. Exosomes are derived from stem cells and delivered as a prepared clinical solution. The source material, mechanism of action, and evidence base differ between them. Neither is a guaranteed treatment for any hair loss condition, and individual outcomes vary significantly with both.
How does PRF work for hair loss?
PRF hair loss treatments are the second generation of PRP therapy, developed to extend the release of growth factors beyond what PRP achieves. The key technical difference is the centrifugation speed: PRF is spun at a slower rate, which keeps more white blood cells and stem cells in the platelet layer and creates a fibrin matrix that acts as a slow-release scaffold.
The treatment process involves:
- Blood draw: A small sample is taken from the arm, similar to a routine blood test.
- Centrifugation: The blood is spun at a lower speed than PRP to produce a denser, more concentrated plasma.
- Preparation: The PRF layer is extracted and prepared for injection.
- Injection: The solution is injected into the scalp or skin treatment area using fine needles.
Because PRF is autologous, the risk of adverse reaction is lower than with synthetic treatments, though a low risk of adverse reaction remains with any injection-based procedure. Hair and Skin Science has offered PRF treatments for hair loss and skin rejuvenation across its Australian clinics.

How do exosomes work for hair loss?
Exosomes are nano-sized extracellular vesicles derived from stem cells. They function as biological messengers, carrying growth factors, proteins, and genetic material between cells. In hair loss treatment, the aim is to deliver these signals directly to hair follicle cells to support follicle activity and scalp health.
Two exosome-based products are used at Hair and Skin Science:
- Exomide Exosomes: A South Korean-developed topical treatment containing over 300 growth factors. Applied to the scalp to support follicle health and encourage cell division.
- ASCE Plus HRLV: An in-clinic solution containing 10 billion exosomes, 10 growth factors, and a combination of biotin, peptides, and amino acids, designed for scalp care and hair loss.
A key distinction: exosomes are acellular. They contain no live cells, which reduces the risk of rejection. Unlike PRF, they are not derived from the patient’s own blood. For a detailed look at both brands, see Exosomes for Hair Loss: A Spotlight on Exosome Brands.
How do PRF and exosomes compare?
Here is a direct comparison across the factors most relevant to a patient deciding between the two:
| Factor | PRF | Exosomes |
|---|---|---|
| Source | Patient’s own blood (autologous) | Stem cell-derived (not autologous) |
| Contains live cells? | Yes (white blood cells, platelets) | No (acellular) |
| Adverse reaction risk | Low, autologous source | Low, acellular formulation |
| Evidence base | More established, builds on PRP research | Growing, newer than PRF/PRP |
| Delivery | Injection into scalp or skin | Topical or injection depending on product |
| Blood draw required? | Yes | No |
| Available at Hair and Skin Science? | Yes | Yes (Exomide and ASCE Plus) |
What can each treatment help address?
Both PRF and exosomes address hair loss and skin rejuvenation, with overlapping but not identical applications.
PRF is commonly used for:
- Androgenetic alopecia (male and female pattern baldness)
- Diffuse hair thinning
- Stress-related hair loss
- Skin rejuvenation, fine lines, and acne scarring
- Under-eye concerns
Exosomes are used for similar hair and skin concerns, and may be considered where patients have poor platelet counts or other factors that affect the quality of autologous treatments. This is a clinical decision made at consultation. All outcome claims for both treatments should be understood as applying to some patients, with results varying between individuals.
Can PRF and exosomes be used together?
Combination approaches are sometimes used clinically. Whether this is appropriate depends on your specific condition, treatment history, and the practitioner’s assessment. A combined approach does not guarantee better results than either treatment alone, and it is not a standard protocol. Your practitioner will advise at consultation if this is worth considering for your situation.
How do you choose between PRF and exosomes?
A practitioner will weigh several factors when assessing which treatment may be more appropriate:
- Platelet health: If platelet count or quality is poor, exosomes may be more suitable since they do not rely on the patient’s blood.
- Severity of hair loss: Both are used across a range of loss stages, though neither is appropriate for areas where follicles have been entirely lost.
- Previous treatments: Patients who have completed a course of PRP or PRF without the desired response may find exosomes worth exploring as an alternative mechanism.
- Tolerance for blood draw: Exosomes require no blood draw, which may be relevant for some patients.
PRF has a more established evidence base and the advantage of using the patient’s own biology. Exosome hair loss therapy is newer, with a growing but still-developing body of clinical research behind it. Both are legitimate options with a place in the treatment menu, and both are available at Hair and Skin Science clinics across Australia.
The most honest answer to which is right for you is: it depends on your situation. Book a free consultation at Hair and Skin Science to discuss which treatment, or combination, is appropriate for your hair loss or skin concern.
