PRP Treatment in Athens

What Is PRP?

PRP stands for platelet-rich plasma.

It is produced from a small sample of the patient’s own blood. The blood is processed in a centrifuge to separate its components and obtain plasma with a higher concentration of platelets.

Platelets are not only involved in clotting. They also contain growth factors and biological signalling molecules, mainly stored within platelet α-granules. These growth factors are part of the reason PRP is used in regenerative medicine, hair restoration, wound healing, orthopaedics, and aesthetic medicine.

However, not every plasma preparation is true PRP. Simply spinning blood does not automatically guarantee a platelet-rich, biologically active, or clinically useful product.

PRP for Hair Loss

PRP is one of the better-supported non-surgical treatments for androgenetic alopecia, also known as male or female pattern hair loss.

When properly prepared and correctly injected, PRP may help improve hair density, reduce shedding, support follicle activity, and improve the overall quality of existing hair in selected patients.

The aim is not to create new hair from nothing. PRP works best when hair follicles are still present and biologically active. It is usually more useful in early or moderate thinning than in areas where follicles have already been permanently lost.

PRP may also be combined with other hair-loss treatments, such as topical minoxidil or other medical therapies, depending on the patient’s diagnosis, age, hair-loss pattern, medical history, and expectations.

A proper consultation should identify whether the patient has androgenetic alopecia, telogen effluvium, inflammatory scalp disease, nutritional deficiency, hormonal factors, or another cause of hair loss. PRP should not be offered blindly before the diagnosis is understood.

Hair Loss Must Be Properly Assessed First

PRP can be useful for selected patients with hair loss, but it should not be offered blindly before the cause of hair loss is understood.

Hair loss can have many different causes. It may be related to androgenetic alopecia, hormonal factors, thyroid abnormalities, nutritional deficiencies, low iron or ferritin, vitamin deficiencies, stress, recent illness, medications, inflammatory scalp conditions, postpartum changes, or other medical factors.

This is why proper assessment is important before treatment. PRP may support follicle activity and improve hair quality in selected cases, but it cannot correct an untreated underlying cause.

For example, if a patient has significant iron deficiency, thyroid imbalance, hormonal disturbance, severe stress-related shedding, or another active medical trigger, PRP alone should not be expected to “do wonders” while the main cause remains untreated.

At Athenaeum Aesthetics, PRP for hair loss begins with understanding the pattern and possible cause of hair loss. In some cases, blood tests, medical history, scalp assessment, medication review, or referral for additional evaluation may be needed before deciding whether PRP is appropriate.

The aim is not simply to inject PRP, but to create a treatment plan that makes biological sense.

Why PRP Quality Matters

PRP is often marketed as a simple treatment: blood is taken, spun in a centrifuge, and injected back into the scalp or skin.

In reality, PRP quality depends on several important variables:

• the volume of blood collected

• the type of anticoagulant used

• the centrifugation protocol

• the relative centrifugal force, not only RPM

• the centrifuge rotor radius

• spin time

• platelet concentration

• leukocyte content

• red blood cell contamination

• plasma volume collected

• sterility of the system

• whether the protocol has been validated

• how soon the PRP is used after preparation

• injection depth and technique

• treatment indication

This is why two clinics can both say they offer “PRP”, while the biological product being injected may be very different.

The Mathematics Behind PRP Preparation

One of the most misunderstood aspects of PRP is centrifugation.

Many people describe PRP preparation only by saying, for example, “we spin at 1500 RPM for 5 minutes” or “we spin at 2500 RPM for 4 minutes.”

This is incomplete.

RPM alone does not tell us the true force applied to the blood sample. The important value is relative centrifugal force, also known as RCF or g-force.

RCF depends on both the RPM and the radius of the centrifuge rotor. The formula is:

RCF = 1.118 × 10⁻⁵ × radius in cm × RPM²

This means that the same RPM can create a different g-force in different centrifuges, because each centrifuge may have a different rotor radius.

Therefore, comparing PRP protocols only by RPM is scientifically weak. A protocol that works in one centrifuge cannot simply be copied to another centrifuge unless the radius and resulting g-force are understood.

This is one of the reasons PRP results can be inconsistent across the market. If the preparation is based on random RPM settings rather than calculated g-force and validated output, the final product may not be true platelet-rich plasma.

Not All PRP Is the Same

PRP is not a single universal product.

Different systems can produce different platelet concentrations, different plasma volumes, different leukocyte content, and different levels of red blood cell contamination.

Some preparations may be platelet-poor plasma rather than platelet-rich plasma. Others may contain unnecessary red blood cells or inflammatory components. Some may be prepared with systems that are not validated for therapeutic reinjection.

This matters because the biological activity of PRP depends on what is actually being injected.

If the final product does not contain an appropriate concentration of platelets and growth factors, the patient may be paying for “PRP” while receiving ordinary plasma with limited regenerative value.

This is one reason some patients believe PRP “does nothing.” In some cases, the issue may not be PRP itself. The issue may be poor preparation, weak concentration, wrong indication, insufficient sessions, or unrealistic expectations.

PRP at Athenaeum Aesthetics

At Athenaeum Aesthetics, PRP is approached with a scientific and protocol-based mindset.

We currently use two different approaches for high-quality PRP preparation.

The first is the Arthrex PRP system, used with the appropriate centrifugation protocol and equipment. Arthrex systems are designed to facilitate the preparation of autologous platelet-rich plasma from a patient’s own blood in a controlled point-of-care setting.

The second is a more customised PRP preparation protocol developed after scientific evaluation and laboratory testing. This approach reflects research carried out by Prof. Marios Papadakis, including assessment of suitable sterile tubes, centrifugation settings, platelet concentration, and growth-factor output.

The aim is not simply to produce plasma. The aim is to produce platelet-rich plasma with meaningful biological potential, using a process that respects sterility, mathematics, reproducibility, and clinical indication.

This reflects our broader philosophy: PRP should not be treated as a low-cost add-on or a vague “regenerative” promise. It should be prepared and used properly, or it should not be offered at all.

PRP for Skin Rejuvenation

PRP is also used in aesthetic medicine for skin rejuvenation.

In the skin, PRP may be used as an autologous injectable or combined with microneedling, laser, or other skin-quality treatments. It may support skin texture, glow, hydration, fine lines, and tissue repair in selected patients.

However, the evidence for PRP in facial rejuvenation is less straightforward than its use in hair loss. Skin ageing is complex. It involves collagen loss, elastin changes, pigmentation, sun damage, skin thinning, volume loss, and changes in facial support.

PRP should not be presented as a replacement for fillers, laser resurfacing, skin tightening, surgery, or other treatments when those are more appropriate.

It is also important to understand that some of the skin benefit may come from the controlled skin injury caused by needling or injection itself. This creates a wound-healing response similar to microneedling. PRP may add a biological regenerative stimulus, but the mechanical stimulation of the skin is also part of the process.

For this reason, PRP for facial rejuvenation should be discussed honestly. It can be useful in selected cases, but it should not be exaggerated or sold as a miracle treatment.

Why Cheap PRP Can Be Misleading

PRP is sometimes offered at very low prices.

This should make patients cautious.

A properly prepared PRP treatment requires appropriate blood collection, sterile handling, suitable tubes or systems, validated centrifugation, correct calculation of g-force, clinical assessment, injection technique, and a treatment plan.

If the price is extremely low, patients should ask what is actually being provided.

Important questions include:

• Is the system suitable for PRP preparation?

• Are the tubes appropriate for therapeutic use?

• Is the preparation sterile?

• Is the centrifuge protocol validated?

• Is the g-force calculated or is only RPM being used?

• Is the final product actually platelet-rich?

• Who is performing the treatment?

• What is the diagnosis?

• How many sessions are needed?

• What result is realistic?

PRP is not comparable to a filler where the patient immediately sees volume after injection. PRP works biologically and gradually. This makes it easier for poor-quality treatments to be offered without obvious immediate feedback.

A patient may pay little, see little, and then conclude that PRP does not work. But the problem may have been the preparation, the indication, the number of sessions, or the treatment plan.

This attitude damages the reputation of a treatment that, when properly prepared and correctly used, has meaningful scientific support in selected indications.

Treatment Plan, Repeat Sessions and When Results Appear

PRP is not usually a one-session treatment.

For hair loss, a typical plan often involves a series of sessions spaced over several weeks, followed by maintenance depending on the patient’s response and ongoing hair-loss pattern.

Results take time because hair biology is slow. Some patients may notice reduced shedding earlier, but visible improvement in hair density, hair quality, or scalp coverage usually takes several months.

In many cases, the first meaningful changes are assessed around 3 to 6 months after starting treatment, depending on the protocol, the number of sessions, the diagnosis, and the patient’s biological response. Some patients may need longer to appreciate the result.

This delayed response is one reason PRP is often misunderstood. Unlike a dermal filler, where volume is visible immediately after injection, PRP works gradually through biological stimulation. The patient does not see an instant result at the time of treatment.

For this reason, expectations must be clear from the beginning. PRP should be judged over months, not days, and usually as part of a properly designed treatment course.

A personalised plan may include PRP alone or PRP combined with other hair-loss treatments, such as minoxidil or other medical therapies, depending on the diagnosis and suitability. If the underlying cause of hair loss is not recognised and addressed, PRP alone may produce limited or disappointing results.

Recovery and Aftercare

PRP treatment usually involves minimal downtime.

After scalp PRP, patients may experience mild tenderness, redness, swelling, or small injection marks. These usually settle quickly.

After facial PRP or PRP combined with microneedling, temporary redness, sensitivity, tightness, or mild swelling may occur.

Patients should follow the aftercare instructions provided at the clinic. This may include avoiding intense exercise, heat exposure, harsh skincare, or certain products for a short period, depending on the treatment area and protocol used.

Risks and Considerations

PRP uses the patient’s own blood, so allergic reaction to the injected material is uncommon. However, PRP is still a medical injectable treatment and should be performed under appropriate conditions.

Possible side effects include discomfort, bruising, swelling, redness, tenderness, temporary headache after scalp injections, infection, asymmetry of response, or limited improvement.

The main risks of poor PRP practice are not only medical complications, but also ineffective treatment due to poor preparation, wrong diagnosis, unrealistic expectations, or inadequate treatment frequency.

A responsible PRP consultation should explain both the potential benefits and the limitations.

PRP Treatment in Vouliagmeni, Athens

Athenaeum Aesthetics is a plastic surgery clinic in Vouliagmeni, Athens, offering PRP treatment for selected hair-loss and skin-quality indications.

Our approach is based on careful evaluation, appropriate patient selection, and scientifically informed preparation. PRP is not treated as a generic beauty treatment, but as an autologous biological product whose quality depends on how it is prepared and how it is used.

Patients considering PRP in Athens are welcome to arrange a consultation to discuss whether PRP is suitable, what protocol is recommended, how many sessions may be needed, and what results are realistic.

What is PRP?

PRP stands for platelet-rich plasma. It is produced from a small sample of the patient’s own blood, which is processed in a centrifuge to separate the plasma and concentrate the platelets.

Platelets contain growth factors and biological signalling molecules that may support tissue repair, follicle activity, and regenerative processes in selected treatments.

Is PRP the same as ordinary plasma?

No. PRP should not be the same as ordinary plasma. True PRP should contain a higher concentration of platelets than baseline blood.

Simply spinning blood in a centrifuge does not automatically guarantee that the final product is platelet-rich or biologically useful. The preparation method, centrifuge settings, tube system, platelet concentration, and sterility all matter.

What is PRP used for?

At Athenaeum Aesthetics, PRP is mainly used for selected hair-loss indications and, in some cases, for skin-quality treatments.

Its strongest aesthetic indication is usually hair loss, especially when hair follicles are still active. PRP may also be used in facial rejuvenation protocols, but expectations should be more cautious and realistic.

Is PRP evidence-based for hair loss?

Yes, PRP has meaningful scientific support for selected cases of hair loss, especially androgenetic alopecia, also known as male or female pattern hair loss.

It may help improve hair density, reduce shedding, support follicle activity, and improve the quality or thickness of existing hair. However, results vary and depend on diagnosis, hair-loss stage, treatment protocol, number of sessions, and individual response.

Do I need an assessment before PRP for hair loss?

Yes. Hair loss should be properly assessed before PRP treatment.

PRP may be useful in selected patients, especially when hair follicles are still active, but it should not be offered without understanding the likely cause of hair loss.

Hair loss may be related to androgenetic alopecia, hormonal factors, thyroid imbalance, nutritional deficiencies, low iron or ferritin, vitamin deficiencies, stress, recent illness, medications, inflammatory scalp disease, postpartum changes, or other medical causes.

A proper assessment helps decide whether PRP is appropriate, whether blood tests are needed, and whether other treatments or medical corrections should be started first.

What happens if the cause of hair loss is not treated?

If the underlying cause of hair loss is not recognised and addressed, PRP alone may have limited results.

For example, if hair shedding is related to iron deficiency, thyroid imbalance, hormonal disturbance, severe stress, nutritional deficiency, or another active trigger, these issues need to be managed as part of the treatment plan.

PRP can support follicle activity in selected cases, but it cannot compensate for an untreated medical or biological cause that continues to drive hair loss.

Can PRP create new hair?

PRP does not create new hair from nothing. It works best when hair follicles are still present and biologically active.

If an area has complete follicle loss or long-standing baldness, PRP is unlikely to create significant new hair growth. In these cases, other options such as medical therapy or hair transplantation may be more appropriate.

Can PRP thicken existing hair?

PRP may help improve the quality, calibre, and density of existing hair in selected patients. This means that hair may appear richer, stronger, or more compact in the same scalp area.

However, this is not guaranteed for every patient. The result depends on the diagnosis, follicle activity, treatment protocol, preparation quality, and biological response.

Can PRP stop hair loss?

PRP may help reduce shedding and support stabilisation of hair loss in selected patients, especially when used early and as part of a proper treatment plan.

However, hair loss is often progressive and multifactorial. PRP should not be presented as a permanent cure. Maintenance sessions and combination treatment may be needed.

Can PRP be combined with minoxidil?

Yes. PRP may be combined with other hair-loss treatments such as topical minoxidil when appropriate.

The best plan depends on the type of hair loss, the stage of thinning, the patient’s medical history, tolerance of treatments, and long-term goals.

How many PRP sessions are needed for hair loss?

PRP for hair loss usually requires a series of sessions. It is not usually a one-session treatment.

A typical plan may involve several sessions spaced over weeks, followed by maintenance depending on the patient’s response and ongoing hair-loss pattern.

The exact number of sessions depends on the diagnosis, hair-loss stage, treatment protocol, preparation quality, and whether other causes of hair loss also need to be addressed.

When will I see results from PRP for hair loss?

PRP results take time because hair biology is slow. Patients should not expect an immediate visible change after one session.

Some patients may notice reduced shedding earlier, but visible improvement in hair density, hair quality, or scalp coverage usually takes several months.

In many cases, the first meaningful changes are assessed around 3 to 6 months after starting treatment, depending on the protocol, number of sessions, diagnosis, and individual biological response.

Why do some people say PRP does not work?

There are several reasons.

PRP may be used for the wrong diagnosis, too late in the hair-loss process, with too few sessions, or with unrealistic expectations. The underlying cause of hair loss may also not have been properly assessed or corrected.

Another important reason is poor preparation. If the final product is not truly platelet-rich plasma, or if it is prepared using random settings without understanding the centrifuge, the patient may receive ordinary plasma rather than a biologically meaningful PRP product.

This is why some disappointing results may reflect poor patient selection, poor diagnosis, poor preparation, or an incomplete treatment plan rather than failure of PRP itself.

Why does PRP preparation matter so much?

PRP quality depends on how it is prepared.

Important factors include the amount of blood collected, the anticoagulant used, the tube or system used, centrifuge type, rotor radius, g-force, spin time, platelet concentration, leukocyte content, red blood cell contamination, sterility, and how soon the PRP is injected after preparation.

This is why not all PRP treatments are the same.

Is RPM enough to judge PRP quality?

No. RPM alone is not enough.

The true force applied to the blood sample is called relative centrifugal force, or g-force. This depends on both the RPM and the radius of the centrifuge rotor.

The formula is:

RCF = 1.118 × 10⁻⁵ × radius in cm × RPM²

This means that two centrifuges running at the same RPM may produce different results if their rotor radius is different. Therefore, saying “we spin at 1500 RPM” or “2500 RPM” is incomplete unless the centrifuge and calculated g-force are known.

Why are not all PRP systems equal?

Different PRP systems can produce different platelet concentrations, plasma volumes, leukocyte content, and levels of red blood cell contamination.

Some systems are designed and validated for PRP preparation. Others may be improvised or not appropriate for therapeutic reinjection. The final product can be very different, even if both treatments are marketed as PRP.

Are standard blood tubes suitable for PRP?

Standard blood collection tubes are designed for blood collection and laboratory testing. They are not necessarily intended, validated, or appropriate for therapeutic PRP preparation and reinjection.

For PRP, the system should be suitable for autologous preparation, sterile handling, and safe reinjection. This is an important part of treatment quality and patient safety.

What PRP systems are used at Athenaeum Aesthetics?

At Athenaeum Aesthetics, PRP is prepared using high-quality, protocol-based methods.

One approach uses the Arthrex PRP system with appropriate centrifugation equipment and protocol. Another approach is a customised protocol developed after scientific evaluation and laboratory testing, including assessment of sterile tubes, centrifugation settings, platelet concentration, and growth-factor output.

The aim is not simply to produce plasma, but to produce platelet-rich plasma with meaningful biological potential.

Is facial PRP as evidence-based as PRP for hair loss?

Facial PRP may be useful in selected skin-quality protocols, but the evidence is less straightforward than for hair-loss treatment.

For facial rejuvenation, PRP may support skin texture, glow, hydration, and tissue repair, especially when combined with microneedling or other skin treatments. However, it should not be presented as a miracle treatment or as a replacement for fillers, laser resurfacing, skin tightening, or surgery when those are more appropriate.

Does facial PRP work because of the PRP or because of the needles?

Both may play a role.

In facial rejuvenation, part of the benefit may come from the controlled skin injury caused by needling or injection, similar to microneedling. This stimulates a wound-healing response.

PRP may add a biological regenerative stimulus through platelets and growth factors, but the mechanical stimulation of the skin is also part of the treatment effect.

Is PRP like a filler?

No. PRP is not a filler.

A filler gives immediate volume because a material is injected into the tissue. PRP works biologically and gradually. Patients should not expect an instant lifting or volumising effect in the same way they might see after dermal fillers.

Why is cheap PRP sometimes misleading?

Very low-cost PRP should make patients cautious.

Proper PRP requires appropriate blood collection, sterile handling, suitable tubes or systems, validated centrifugation, correct g-force calculation, clinical assessment, injection technique, and a treatment plan.

If the treatment is extremely cheap, patients should ask what is actually being prepared and injected. Poor-quality PRP may damage the reputation of a treatment that can be useful when prepared and used correctly.

Is PRP painful?

PRP involves blood collection and multiple small injections. Discomfort is usually tolerable, but sensitivity varies between patients and treatment areas.

Scalp injections may feel more sensitive than facial injections in some patients. The treatment is usually well tolerated.

Is there downtime after PRP?

Downtime is usually minimal.

After scalp PRP, patients may have mild redness, tenderness, swelling, or small injection marks. After facial PRP or PRP combined with microneedling, temporary redness, tightness, sensitivity, or mild swelling may occur.

These effects usually settle quickly.

Is PRP safe?

PRP uses the patient’s own blood, so allergic reaction to the injected material is uncommon.

However, PRP is still a medical injectable treatment. It should be prepared and performed under appropriate conditions, using suitable sterile systems and proper technique.

Possible side effects include bruising, swelling, redness, tenderness, discomfort, infection, temporary headache after scalp treatment, or limited improvement.

Who is a good candidate for PRP?

A good candidate depends on the indication.

For hair loss, PRP is usually more suitable for patients with early or moderate thinning where follicles are still active and where the cause of hair loss has been properly assessed.

For facial rejuvenation, it may be suitable for selected patients who want gradual improvement in skin quality, especially as part of a broader skin plan.

Who may not be suitable for PRP?

PRP may not be suitable for patients with certain blood disorders, platelet problems, active infection, some inflammatory conditions, severe uncontrolled medical issues, or unrealistic expectations.

It may also be unsuitable when the hair-loss diagnosis is unclear, when the underlying cause has not been addressed, or when the area has advanced follicle loss. A consultation is necessary before treatment.

Can PRP be repeated?

Yes. PRP is commonly performed as a course of treatments and may be repeated as maintenance depending on the indication and response.

For hair loss, maintenance sessions may be recommended because androgenetic alopecia is usually a long-term condition.

Can PRP results be guaranteed?

No. PRP results cannot be guaranteed.

The outcome depends on diagnosis, biological response, preparation quality, platelet concentration, treatment protocol, number of sessions, and whether the indication is appropriate.

A responsible consultation should explain both the potential benefits and the limitations.
