Human blood consists of red blood cells, white blood cells, platelets and plasma. Platelets are small cells that contain “growth factors”.

In case of injury, platelets allow, thanks to the growth factors, to ensure the repair of the tissue and its healing. More concretely, the platelets allow microcirculation activation and therefore the stimulation of hair follicle stem cells.

PRP (Platelet Rich Plasma) is a technique widely used in different fields of medicine (tendinitis, burn treatment, facial aesthetics, dental implants …).

Various publications have shown very encouraging results in the treatment of androgenetic alopecia.

PRP treatments consists of isolating the platelets from a blood sample and concentrating them by centrifugation and injecting them back into the area where repair is desired.

This treatment can be used alone or in combination with other medical hair loss protection treatments or hair transplants.

The doctor takes a 10 mL blood sample. The blood is placed in a RegenBCT® tube, which is known for its safety and performance.

The blood is placed in a centrifuge for 5 minutes to separate the PRP from other components.

Between 5 and 6 mL of PRP are extracted from the tube.


After local anesthesia of the scalp, the highly concentrated PRP is directly reinjected with a micro-needle in areas to be “repaired”. Multiple injections are done in one session.

There are many benefits to using PRP:

  • No risk of rejection or infection as injected PRP comes from the patient’s own blood
  • Simple, reliable and safe procedure
  • Non-surgical intervention
  • Fast recovery
  • No pain thanks to local anesthesia
  • Stimulation and strengthening of grafts after transplant
  • Verification of effectiveness by digital phototrichogram


In rare instances, redness and compression sensations may appear on the scalp a few hours after the injections.


Each session lasts for 30 minutes and the protocols adapt according to the patients. In general, the protocol is as follows: 2 sessions at 3 months, then 1 to 2 sessions each year.

A digital phototrichogram of control is performed at each session.

Results are generally observed from the 2nd session, this observation may vary depending on the patient’s response rate to the treatment.


One PRP session costs 500 euros.



The first evaluations may show an increase in the number of terminal hair per square centimeter (capillary density) and an increase in the diameter of the hair.

How do I know if PRP is right for me?

You can make an appointment to see a doctor for a diagnosis and treatment plan.

How many treatments are required?

Usually 2 sessions in 3 months are recommended, then 1 session every year.  But this treatment plan may change from patient to patient.

What results can I expect?

For visible results it is essential to repeat the sessions instead of stopping after the first one. Results may be apparent after the 3rd month.

Is the procedure painful?

There may be some sensitivity. However, we always use a local anesthetic and when necessary may also use a topical anesthetic cream for pain.

What side effects might I expect?

Redness may develop at the treatment site but will disappear in 4-5 hours.

Can I resume normal activities after my PRP treatment?

Yes, but we recommend avoiding dyes or strong products your hair for 48 hours.

Is PRP a cure for baldness?

PRP is not a cure for baldness (the final stage of androgenic alopecia) because genetic pathology will remain. However, regular treatments significantly slow down the effects of baldness and may increase the density and thickness of the hair.

Can I have PRP treatments after a hair transplant?

PRP treatments can be used in addition to a hair transplant. It can recover miniaturized hair, very thin and visibly weakened whose bulb is still alive but largely atrophied and therefore liely to die quickly.
