The Platelet Rich Plasma (PRP) commonly used in hair restoration is “autologous,” meaning that it is derived from the patient’s own blood. To obtain PRP, a patient’s blood is spun in a centrifuge to separate the solid from liquid components and platelet activators, such as thrombin, calcium chloride and sometimes collagen, are added. The separated “solid” portion of the blood is PRP (platelet rich plasma).  PRP is then placed into a syringe and injected into the area of hair loss.  When used to stimulate hair growth, multiple treatment sessions are required. Some improvement (in reversing miniaturization) can be expected in the first 2-6 months. The treatments must be continued periodically to maintain any improvement.

How does platelet rich plasma stimulate hair growth? 

Platelet rich plasma promotes local tissue growth and repair of damaged tissue by releasing growth factors, which interact with the cells and stimulate cell reproduction. PRP also helps initiate new vascular supply in the tissue, which adds healthy color and evened skin tone. PRP will increase the number of stem cells in the area and the production of collagen. These benefits together make the skin appear smoother and firmer giving the patient a more youthful look.

The Procedure

Blood is collected. About 2-4 vials of blood are drawn on the day of the procedure.

A centrifuge is then used to separate plasma and platelets from the red blood cells.

PRP is extracted and mix with a vitamin rich serum to activate the cells.

The platelet rich plasma is then spread onto the scalp. The Rejuvapen is then used to push the PRP into the skin and glides freely and easily over the tissue.

PRP is applied with either the Rejuvapen and/ or injection. The Rejuvapen pushes the PRP into the dermal layer. The remaining PRP can be injected into specific areas of the patient that need the most improvement.

If PRP therapy is appropriate, we can begin your PRP treatment at the time of your consultation. After the initial treatment session, we will administer the next two subsequent treatments at 4 week intervals. Additional treatments are given at three-month intervals depending on the response.

The treatments are administered by a physician and take about an hour. Patients are monitored photographically to assess the benefits of therapy. We will modify your treatment schedule based on your individual response to therapy.


For the medical treatment of hair loss, practitioners use PRP to stimulate the growth of follicles, thereby reversing the hair miniaturization seen in female pattern hair loss and in male pattern hair loss.

It is conjectured that the introduction of platelets and white blood cells through PRP can amplify the body’s naturally occurring wound-healing mechanism. It is also proposed that PRP can actually stimulate the stem cells (dermal papilla) of the newly transplanted hair follicles.
