PRP is an exciting non-surgical procedure for men and women who are experiencing hair loss on the scalp or eyebrows. PRP has been shown for decades to be a safe and effective method to help repair and revitalize tissue. In hair restoration, new evidence supports PRP therapy as a promising treatment to promote hair growth. There are increasing numbers of medical journal articles showing the efficacy of PRP in increasing hair count, hair thickness, and the growth phase of the hair cycle.
If the hair follicles or hair roots are healthy, the growth of the hair is healthy. Hair follicles survive on the nutrition they get from blood supply. When the scalp is injected with PRP, growth factors are released that stimulate stem cells and other cells in the microenvironment of the hair follicle resulting in hair follicle growth, increased circulation to the hair follicles, and decreased inflammation. These growth factors also stimulate inactive hair follicles into an active growth phase.
The patient’s blood is drawn and spun down using a specialized piece of equipment called a centrifuge to separate the red and white blood cells from the portion of the blood rich in platelets.
This plasma which is now concentrated 5-7 times the platelets in whole blood is activated by injecting it into the highly vascular scalp. This activation of the platelets causes the release of 8 different growth factors which help regenerate tissue and bring new blood flow to the area. Prior to the injection, a topical numbing cream is applied to the scalp making the procedure virtually painless.
There is little to no downtime following the procedure. Hair may be washed following the procedure, but it is best to avoid hair products, coloring, and excessive styling for 1-2 days following. Our patients often like to bring a hat to wear for after their procedure, especially if planning to go somewhere before heading home. Results will typically be seen within 2-3 months of treatment.
Our protocol consists of a series of 2 PRP treatments 5-6 weeks apart followed by repeat treatments every 6-12 months depending on the individual and reason for hair loss. In certain situations, results could be permeant requiring no further treatment.
As with all PRP treatments, results will vary based on the individual. Often patients, particularly men, will benefit from a multimodal approach which may include Light therapy, minoxidil, DHT blockers, or hair follicle transplant.
