Platelet-Rich Plasma (PRP)
Platelet-Rich Plasma (PRP) is processed blood plasma, a concentration of plasma with platelets from which red blood cells and white blood cells are removed. This concentration of PRP taken from the patient’s own blood is injected into the scalp to promote hair growth. The scalp is that the skin that covers the top part of your head. Platelets are known to be a reservoir of growth factors that stimulate tissue recovery by increasing blood flow and cytokines. They are known to be responsible for stimulating and enhancing hair follicle function. PRP therapy for hair loss is a three-step medical treatment in which a person’s blood is drawn, processed, and then injected into the scalp. Some in the medical community think that PRP injections trigger natural hair growth and maintain it by increasing blood supply to the hair follicle and increasing the thickness of the hair shaft. Sometimes this approach is combined with other hair loss procedures or medications.
PRP therapy process
PRP therapy is a three-step process. Most PRP therapy requires three treatments 4–6 weeks apart. Maintenance treatments are required every 4–6 months.
Your blood is drawn — typically from your arm — and put into a centrifuge (a machine that spins rapidly to separate fluids of different densities).
After about 10 minutes in the centrifuge, your blood will have separated into in three layers:
- platelet-poor plasma
- platelet-rich plasma
- red blood cells
The platelet-rich plasma is drawn up into a syringe and then injected into areas of the scalp that need increased hair growth. Each treatment takes a few minutes and causes no downtime or adverse side effects.
For best results, consistency is the key. Treatments are typically performed once a month for the first three to four months, and even every three to six months thereafter, depending on the individual patient’s response and results. Following this protocol, anticipated results can first be seen within two to three months.
