For hair rejuvenation, this PRP isn’t injected into an injured area, but it is injected in dozens of tiny injections across the areas of the scalp that have thinning hair.
Platelet-rich plasma (PRP) has been used by professional athletes for a couple decades to help them recover more quickly from injury or surgery. The idea is to put the powerful healing functions and growth factors in blood platelets to work repairing the area.
To create PRP, a blood sample is taken and put into a centrifuge, which separates out the red blood cells.
This creates a serum of concentrated blood platelets, white blood cells, and blood plasma — PRP.
For hair rejuvenation, this PRP isn’t injected into an injured area, but it is injected in dozens of tiny injections across the areas of the scalp that have thinning hair. The PRP stimulates the stem cells and other cells in the microenvironment of the hair follicles.
The idea is to stimulate hair follicles that have become dormant or inactive, returning them to the active growth phase. More follicles in the growth cycle mean more hair growth. It’s thought that the various growth factors in PRP provide the stimulus. This starts a process of boosting hair growth again where it was once thinning.
