Platelet Rich Plasma (PRP)
for Hair Loss
What is PRP?
Human blood is comprised primarily of red blood cells (RBC), as well as white blood cells (WBC), platelets, and plasma. By initiating the first step of coagulation, platelets are the key to the body’s ability to heal wounds. It is thought that by increasing the platelet count in a wounded area, the body’s healing to that area would be accelerated explaining the use of PRP (platelet rich plasma) in wound healing.
Platelet rich plasma is concentrated blood plasma which contains approximately five times the number of platelets found in normal circulating blood. In addition, blood plasma contains the growth factors PDGF and VEGF and other bioactive proteins that aid in wound healing.
Mechanism of Action in Hair Transplants
Hair follicles survive through the absorption of oxygen from surrounding tissue. It is conjectured that the introduction of platelets and white blood cells through platelet rich plasma (PRP) would amplify the body’s naturally occurring wound healing mechanism.
Others propose that PRP can actually stimulate the stem cells (dermal papilla) of the newly transplanted hair follicles. This procedure can be performed during hair transplant surgery, post surgery or as a procedure that delays the hair loss stage.
Androgenetic alopecia, a hereditary and androgen-dependent progressive thinning of the scalp hair in a defined pattern, is a common dermatological disorder that affects men and some women – and often leads to a significant negative impact on social and psychological well-being. It is this often embarrassing effects of this condition that PRP for hair loss is designed to combat.
The treatment is less invasive than options like hair implants – and often with more natural and aesthetically pleasing results. More often than not, one would require at least 6 treatments 4 to 6 weeks apart from each other and then one treatment a year for maintenance.
PRP hair treatment has been widely recognized throughout the medical community as a safe and cost-effective method for alleviating hair loss, patients can expect an improvement in density and thickness in the areas that are concerning them.
In a nutshell, the PRP hair treatment is injected into the scalp, causing miniaturized hair follicles to become healthier and larger, producing more robust hair growth.
