Platelet-Rich Plasma (PRP) Therapy
Over the years, there has been a lot of research done on platelet-rich plasma, referred to as “prp”, and its possible effectiveness in the management of hair loss. Let’s answer a few questions you may have regarding what exactly PRP is and how it works to promote hair growth?
Before we go into how prp works, let’s go through a couple basic definitions of some important terms: Platelet, Plasma, and then Platelet-Rich Plasma.
- Platelet: A platelet is a kind of white blood cell that’s made up of about 50 to 80 tiny condensed structures called alpha-granules. Each alpha-granule has a large number of growth factors, many playing a fundamental role in healing after skin damage. Several of these platelets are also known to control the growth cycle of hair follicles.
- Plasma: Blood plasma is what keeps the red & white cells suspended in liquid. There are 3 standard kinds of blood cells: white blood cells (whose main function is to help fight off infection), red blood cells (that transport oxygen), and platelets (that help with blood clotting, and repair).
- Platelet-Rich Plasma: Platelet rich plasma comes from a person’s own blood plasma. It is concentrated blood plasma which contains around 5-8 times the amount of platelets usually found in the blood.
How is PRP made?
To make a PRP preparation, blood has to be first taken from a patient. To separate the solid from liquid components and platelets, the blood is spun in a centrifuge. The separated “solid” portion of the blood is PRP (platelet rich plasma).
The science of prp and how it works:
PRP contains special cells called Platelets, that can hypothetically cause growth of the hair follicles by stimulating the stem cells and other cells around the hair follicle. These platelet cells are responsible for: stimulating healing, speeding up the rate and amount of tissue healing and restoration, responding to injury, and formation of new cellular growth. The main purpose of using PRP in hair restoration is to stimulate inactive or freshly restored hair follicles into an active growth phase. The PRP is then placed into a syringe and reinstated into the area of hair loss. PRP be can be laid into the donor incision, sprayed onto a recipient area after and during a hair transplant, or injected directly into hair thinning scalp. Before injecting PRP, the doctor will often create a ring-block of local anesthesia with 1% lidocaine.
Must the procedure be done more than once & when will you see results?
When PRP is used to promote hair growth, most patients require repeat treatment in about 1 to 2 years. Because results vary from patient to patient, the treatments may need to be continued intermittently to maintain any improvement. This will depend on, final goals, amount of hair loss, and patient’s response to therapy. Most patients will see results within 3-6 months.
