What is PRP?

PRP is platelet-rich plasma, a product that is present in the blood. Platelet-rich plasma is a nutrient-dense fluid that stimulates cellular regeneration within microenvironments like the hair follicles, joints, and also the skin. Platelets are robust cells that contain numerous growth factors, each of which is involved in certain cellular processes.

Platelet-rich plasma has a long history of medicinal use related to tissue healing and regeneration. It is no surprise that this therapy has made its way into the field of hair restoration.

How does PRP work for hair restoration?

The primary purpose of PRP treatment for hair loss is to stimulate activity in the hair follicles. This may prompt an active phase of hair growth in follicles that have become inactive. PRP injections into the scalp may also support the active phase of newly implanted hair follicles. This occurs through the action of various growth factors.

Platelets contain:

• Platelet-Derived Growth Factor (PDGF), which is involved in fibrin formation, blood vessel growth, and cell regeneration.
• Vascular Endothelial Growth Factor (VEGF), involved in the formation of new blood vessels.
• Fibroblast Growth Factor-2 (FGF-2) is also involved in blood vessel formation, as well as the generation of specialized cells that heal and rejuvenate.
• Transforming Growth-Factor-Beta (TGF-b) is involved in bone metabolism in the body as well as matrix formation between cells.
• Epidermal Growth Factor (EGF) stimulates collagen proliferation and cell growth as well as blood vessel formation.
• Insulin-Like Growth Factor – (IGF) provides necessary physiological regulation in nearly every cell.
