What is Platelet Rich Plasma (PRP)?

Platelet Rich Plasma is an autologous therapy frequently used for the treatment of hair loss and rejuvenation.

PRP (Platelet Rich Plasma) therapy for hair loss is a three-step medical treatment in which blood is extracted, processed, and injected into the scalp.

Some in the medical community think that PRP injections trigger natural hair growth and maintain it by increasing the blood supply to the hair follicle and increasing the thickness of the hair shaft. Sometimes this approach is combined with other hair loss treatments or medications.

There hasn't been enough research to prove if PRP is an effective hair loss treatment. However, PRP therapy has been used since the 80s. It has been used for problems such as healing tendons, ligaments, injured muscles, and dental procedures.

Where is the PRP obtained from?

In this therapy, a blood sample is taken from the patient. The blood is subjected to a centrifugation process to separate the platelet-rich fraction from the whole blood. Multiple growth factors are found in the platelet-rich fraction.

What are growth factors for?

These factors are highly concentrated in the preparation of Capillary Plasma. When injected directly into the scalp, they stimulate hair growth.

How does Platelet Rich Plasma in Hair work?

The mechanism by which growth is stimulated is by a shortening of the telogen phase a prolongation of the anagen phase.

Controversy over its effectiveness

There has not been enough research to prove if PRP is effective. It is also unclear for whom, and under what circumstances, it is most effective.

Although according to a recent study, “Although PRP has sufficient theoretical scientific basis to support its use in hair restoration, hair restoration using PRP is still in 'infancy'. The clinical evidence is still weak. '

Does the PRP only apply once?

For the therapy to work optimally it must be applied periodically.

PRP therapy process

PRP therapy is a three-step process. Most PRP therapies require three treatments 4 to 6 weeks apart.

Maintenance treatments are required every 4-6 months.

Step 1:

Blood is drawn - typically from your arm - and put into a centrifuge (a machine that spins rapidly to separate fluids of different densities).

Step 2:

After about 10 minutes in the centrifuge, your blood will have separated into three layers:

  1. Plasma
  2. White blood cells
  3. Red blood cells

Plasma is separated into 3 visually indistinguishable portions or fractions, but within them there is a different concentration of platelets:

  • Platelet Poor Plasma
  • Platelet Medium
  • Platelet Rich Plasma

Step 3:

Platelet-rich plasma is drawn into a syringe and then injected into the areas of the scalp that need further hair growth.

PRP for hair loss side effects

Because PRP therapy involves injecting your own blood into the scalp, you are not at risk of contracting a contagious disease or relevant side reactions.

Still, any therapy that involves injections always carries a risk of side effects such as:

  • Injury to blood vessels or nerves
  • Infection
  • Calcification at injection sites
  • Healing tissue

There is also the possibility that you will have a negative reaction to the anesthesia used in therapy, if you have previously received anesthesia.
