Platelet Rich Plasma Therapy (PRP) for Hair Loss
PRP is blood plasma containing a concentration of platelets many times greater than occurs normally in blood.
Blood consists of approximately 93% red blood cells (RBC), 1% white blood cells (WBC) and 6% platelets, all suspended in plasma. The basis for the benefit of platelet rich plasma lies in decreasing the RBC count to 5% since they are less useful in the healing process while increasing
In addition, every platelet is also a biochemical storehouse of regulatory, signaling and growthfactor molecules that participate in recovery and healing of tissue in response to injury. Growthfactor molecules associated with platelets include:
All of these growth factors initiate and enhance physiologic processes that contribute to tissue recovery and health after injury. The growth factors are also involved in normal physiologic processes such as blood vessel formation.
PRP injections artificially increase the number of platelets at a site where the storehouse of growth factors in the platelets can be put to use in enhancing tissue recovery, repair and health.
How is PRP collected?
Blood is withdrawn from a patient’s arm by syringe, as it would be for any
Plasma defined as platelet-rich plasma contains four to eight times the
The platelet rich plasma is injected into areas of scalp that show hair
PRP in Hair Loss
The aim of using PRP is to make use of the full array of platelet-associated growth factors to preserve and enhance hair follicle viability by reinvigorating dormant hair follicles, thus stimulating new hair growth.
Investigators in the USA conducted a small study of PRP effect on dormant hair follicles. The study hypothesized that platelet growth factors can "wake up" dormant hair follicles and begin the production of new hair. PRP was applied after scalp skin was slightly injured to induce platelets to release growth factors at the injury site. Enhanced hair growth and hair diameter was noted over the next four months.
Safety, Complications and Contraindications to the use of PRP
PRP is immunologically neutral and poses no danger of allergic, hypersensitivity or foreign-body reactions.
Sterile technique must be used at every stage of PRP preparation and application. Sterile technique is especially important if a patient has an underlying medical condition that predisposes to infection.
A brief period of inflammation at wound sites may be experienced by a patient after PRP treatment. Inflammation may be associated with release of platelet-associated factors at the wound site.
Some medical conditions may be a contraindication to the use of PRP. Many of these are not absolute contraindications because the conditions vary from patient to patient. It is wise to raise the question with us when the use of PRP is discussed.
