PRP hair treatment has become one of the most widely used non-surgical options for people dealing with early thinning, and it works by using a concentrated portion of your own blood to stimulate the scalp. In simple terms, a small sample of your blood is spun in a centrifuge to separate out platelet-rich plasma, which is then injected into thinning areas to strengthen existing hair follicles. It is not a hair transplant and it will not create new follicles, but for the right candidate it can slow shedding, improve density, and support results after a transplant.
Key Takeaways
- PRP uses your own blood, so there is no synthetic drug involved and the risk of allergic reaction is very low.
- It strengthens follicles you already have rather than replacing lost ones, which makes early-stage thinning the ideal scenario.
- A typical starting protocol is 3–4 sessions spaced about a month apart, followed by maintenance every 4–6 months.
- Results are not permanent on their own; ongoing sessions are needed to sustain the benefit.
- PRP is frequently combined with a hair transplant to support graft survival and protect surrounding native hair.
- Approximate cost per session ranges from EUR 150 to 400, depending on the clinic and protocol.
What Is PRP Hair Treatment?
PRP stands for Platelet-Rich Plasma. Your blood is made up of red cells, white cells, plasma, and platelets. Platelets are best known for helping blood clot, but they also carry a rich supply of growth factors — proteins that signal cells to repair, regenerate, and grow. PRP treatment concentrates these platelets into a small volume of plasma and delivers them directly to the scalp, where the growth factors can act on struggling hair follicles.
The idea is straightforward: instead of introducing an external medication, the treatment amplifies your body's own repair signals in the exact area where hair is thinning. Because the material comes entirely from you, PRP is considered a low-risk, minimally invasive procedure. It is performed in an outpatient setting and usually takes under an hour from blood draw to final injection.
It is important to be honest about what PRP is not. It is not a cure for baldness and it cannot regrow hair in areas where follicles are completely gone. Where the follicle has died and the scalp is smooth and shiny, there is nothing left for the growth factors to act upon. PRP works on follicles that are still alive but weakened or miniaturised.
How Does PRP Work?
The mechanism relies on the growth factors released by concentrated platelets. When injected into the scalp, these proteins are thought to support hair follicles in several ways:
- Prolonging the growth (anagen) phase of the hair cycle, so hairs stay in active growth longer.
- Improving blood supply to the follicle by encouraging small new vessels, which brings more oxygen and nutrients.
- Reversing miniaturisation, the process where follicles produce progressively thinner, weaker hairs before they stop.
- Reducing inflammation around the follicle that can accelerate shedding.
In practice, patients often notice less shedding first, usually within the first two to three months. Visible improvements in thickness and density tend to appear later, around three to six months, once several sessions have been completed and the hair cycle has had time to respond. Because hair grows slowly, patience is essential — PRP is a gradual process, not an overnight fix.
The PRP Procedure Step by Step
The full session is quick and follows a consistent sequence. The table below outlines what happens from start to finish.
| Step | What Happens | Approx. Time |
|---|---|---|
| 1. Consultation | Scalp assessment and confirmation you are a suitable candidate | 10–15 min |
| 2. Blood draw | A small sample (around 10–20 ml) is taken from your arm | 5 min |
| 3. Centrifugation | The sample is spun to separate platelet-rich plasma | 10 min |
| 4. Preparation | The concentrated plasma is drawn into a syringe | 5 min |
| 5. Numbing | Optional topical anaesthetic or cooling for comfort | 10 min |
| 6. Injection | Plasma is injected into thinning areas of the scalp | 15–20 min |
| 7. Aftercare | Brief instructions; you return to normal activity same day | 5 min |
There is no downtime. Most patients drive themselves home and resume work the same day. You may be asked to avoid washing your hair, heavy exercise, alcohol, and direct sun for 24–48 hours to let the scalp settle.
Who Is PRP Suitable For?
PRP is most effective for people in the early to middle stages of hair loss, where follicles are weakened but still present. Good candidates typically include:
- Men and women with early androgenetic (pattern) thinning.
- People noticing increased shedding or reduced density rather than fully bald patches.
- Patients with certain types of alopecia where follicles remain viable.
- Transplant patients who want to protect and strengthen both grafts and native hair.
PRP is generally less suitable for advanced baldness with no viable follicles, and it may be inappropriate for people with certain blood disorders, active scalp infections, those on blood-thinning medication, or during pregnancy. A proper consultation is the only reliable way to know whether PRP is right for you. If you are still deciding on your overall approach, our guide on how to stop hair loss covers the full range of options.
How Many Sessions Are Needed?
PRP is not a single-visit treatment. The follicles need repeated stimulation to respond, so a course of sessions is standard. A typical plan looks like this:
| Phase | Frequency | Purpose |
|---|---|---|
| Initial course | 3–4 sessions, 1 month apart | Kick-start follicle response |
| Assessment | After the initial course | Review shedding and density |
| Maintenance | Every 4–6 months | Sustain and protect results |
The exact number varies with the degree of thinning and how your scalp responds. Some patients see enough improvement after the first course to move straight to maintenance; others benefit from a longer initial phase. Your specialist will personalise the schedule at your assessment.
Is PRP Permanent?
This is one of the most important honest points to understand: PRP is not permanent. It does not stop the underlying cause of pattern hair loss, which is largely genetic and hormonal. PRP supports and strengthens follicles while treatment continues, but the effect fades over time if sessions stop.
Think of it as maintenance rather than a one-time fix — similar to how ongoing care sustains many cosmetic and dermatological results. Without follow-up sessions, the follicles gradually return to their previous trajectory. This is why maintenance every few months is built into most protocols, and why PRP is often paired with medical treatments such as minoxidil or finasteride under medical supervision to address the hormonal driver directly.
PRP vs Mesotherapy
PRP is often compared with hair mesotherapy because both are injectable, non-surgical scalp treatments. The key difference is what gets injected: PRP uses your own blood-derived plasma, while mesotherapy uses a prepared cocktail of vitamins, minerals, and other nutrients. The table below compares them.
| Feature | PRP | Mesotherapy |
|---|---|---|
| Injected material | Your own platelet-rich plasma | Vitamin/nutrient cocktail |
| Source | Drawn from your blood | Manufactured solution |
| Main action | Growth-factor stimulation | Nourishes scalp and follicles |
| Allergy risk | Very low (autologous) | Slightly higher (external agents) |
| Blood draw needed | Yes | No |
| Typical course | 3–4 sessions + maintenance | Multiple sessions + maintenance |
Neither is universally "better" — the right choice depends on your scalp, goals, and specialist assessment. In some cases they are used at different stages of a treatment plan. You can read more in our dedicated guide to hair mesotherapy.
Using PRP Alongside a Hair Transplant
PRP is one of the most common complementary treatments for transplant patients, and it is used at more than one point in the journey:
- Before surgery, to strengthen native hair in and around the recipient area.
- During the procedure, where some clinics bathe grafts in plasma to support survival.
- After surgery, to encourage healing, reduce shedding of native hairs, and support graft integration.
The goal is to give transplanted follicles the healthiest possible environment and to protect the surrounding hair that was not transplanted. It does not replace the transplant or change the surgical result, but it can be a useful supporting tool. If you are planning surgery, our hair transplant recovery timeline explains how PRP fits into the healing weeks.
Side Effects and Safety
Because PRP uses your own blood, it is considered a very safe procedure with a low risk profile. There is essentially no chance of an allergic reaction to the plasma itself, since it is autologous. That said, injections into the scalp can cause some temporary, minor effects:
| Possible Effect | Typical Duration | Notes |
|---|---|---|
| Mild tenderness | 1–2 days | At injection sites |
| Redness | A few hours to a day | Settles quickly |
| Slight swelling | 1–2 days | More common on the forehead |
| Small bruising | A few days | At the blood-draw or injection site |
| Temporary headache | Same day | Uncommon and mild |
Serious complications are rare when the procedure is performed by trained professionals using sterile technique. Risks increase only if hygiene is poor or if the patient has an unsuitable medical background — which is exactly why the pre-treatment consultation matters. Always choose a licensed, medically supervised clinic.
Approximate Cost of PRP
PRP is priced per session, and because a course involves several sessions, it helps to think in terms of the full plan rather than a single visit. Costs vary by country, clinic, and the specific protocol used.
| Item | Approximate Range |
|---|---|
| Single PRP session | EUR 150 – 400 |
| Initial course (3–4 sessions) | EUR 450 – 1,600 |
| Maintenance session | EUR 150 – 400 |
| PRP added to a transplant package | Often included or discounted |
At Hairvard, PRP is frequently offered as part of a wider treatment or transplant plan, which can make it more cost-effective than booking sessions individually. The best way to get an accurate figure for your situation is a personal assessment, since the number of sessions you need directly affects the total.
Frequently Asked Questions
Does PRP hurt?
Most patients describe it as mild discomfort rather than pain. A topical numbing cream or cooling can be used to make the scalp injections more comfortable.
How long until I see results from PRP?
Reduced shedding often appears within two to three months, with visible improvements in density typically around three to six months after starting a course.
Is PRP a replacement for a hair transplant?
No. PRP strengthens existing follicles but cannot create new hair in bald areas. A transplant is needed to restore hair where follicles are gone.
How often do I need PRP sessions?
A common plan is three to four initial sessions a month apart, followed by maintenance every four to six months to sustain results.
Can women have PRP?
Yes. PRP is suitable for both men and women with early thinning and viable follicles, and it is commonly used for female pattern thinning.
Are the results permanent?
No. PRP results fade if sessions stop, because it does not address the genetic cause of pattern hair loss. Maintenance is required.
Is PRP safe?
It is considered very safe because it uses your own blood, which removes the risk of allergic reaction to the injected material. Side effects are usually minor and temporary.
Can I combine PRP with minoxidil or finasteride?
Yes, and this is common. Medications address the hormonal cause while PRP supports the follicles, but both should be used under medical supervision.
How much blood is taken for PRP?
Usually a small sample of around 10 to 20 ml, similar to a routine blood test.
Is there any downtime after PRP?
No. Most people return to normal activities the same day, though heavy exercise, alcohol, and sun exposure are best avoided for a day or two.
Does PRP work for everyone?
No treatment works for everyone. PRP is most effective for early-stage thinning with viable follicles and is less useful for advanced baldness.
Can PRP be done after a hair transplant?
Yes. It is often used after surgery to support healing, reduce shedding of native hair, and help create a healthy environment for the grafts.
How is PRP different from mesotherapy?
PRP uses your own plasma and its growth factors, while mesotherapy injects a prepared cocktail of vitamins and nutrients. They can serve different roles in a plan.
