Stimulating hair growth with PRP

Hair loss starts, on average, from the age of 25 in men and 40 in women. This is often due to hormonal problems, thyroid problems or genetics. Several treatments are available to combat this hair loss, including PRP, which is a platelet-rich plasma injection. How does this stimulate hair growth? What does a session involve? Find our answers below.

What is PRP (Platelet-Rich Plasma)?

PRP (Platelet Rich Plasma), also known as platelet mesotherapy, boosts hair growth, cell regeneration and the formation of new blood vessels by using plasma and platelets present in the blood. As a result, the stem cells in the hair follicles of the scalp are stimulated by injecting platelet growth factors.

Platelet-rich plasma injections are particularly suitable for people with:

  • mild to moderate alopecia,
  • thinning hair or partial baldness,
  • women who have experienced hair loss following a pregnancy.

For a very noticeable lack of hair, stimulation is more complicated and sometimes impossible. Indeed, PRP stimulation can only be performed if there is an existing bulb. If baldness is more marked, you can always choose FUE hair micrografting, alongside a PRP treatment to stimulate the growth of the grafts by stimulating the scalp.

This treatment eliminates any risks of allergies or rejection.

What does a PRP session involve?

The procedure is simple and quite quick. First of all, after an initial consultation with a Lazeo physician, a standard blood sample is taken.

This sample is then centrifuged to separate the plasma and platelets from other blood components.

The PRP is then injected into the scalp at several points. At this stage, an anesthetic cream may also be applied to the scalp to maximize patient comfort.

You can resume your activities immediately afterwards. You may notice some redness and slight bruising after the procedure, which will disappear very quickly. You should also refrain from dyeing your hair or using products that are aggressive for the hair and scalp in the days following the session.


Generally, 5 sessions spaced one month apart are required to achieve optimal and long-lasting results. An annual maintenance session is recommended to preserve the effects of PRP.


Platelet-rich plasma injections are contraindicated in the following cases:

  • pregnancy/breastfeeding,
  • autoimmune disease,
  • diabetes,
  • skin disease,
  • skin inflammation,
  • blood disease,
  • cancer,
  • anticoagulant or antiaggregant treatment,
  • treatment that alters wound healing.

The prices of PRP injections

The price of a PRP injection varies according to the treatment area and your needs. The price starts at €350 per session. However, for more information, it is advisable to make an appointment for an initial consultation (free of charge) to establish a more precise treatment protocol.
