Platlet Rich Plasma (PRP) therapy was first used in 2009 to regenerate and stimulate hair. PRP is a relatively new procedure when it comes to hair restoration, but there have been some very good results. PRP utilizes the growth factors that are within a patient’s own blood. This blood is drawn as part of the PRP process. The process is non-invasive and painless for many. Only the top of the scalp needs to be anesthetized.
Why are Platelets Good for Hair Growth?
Your blood consists of 1% white blood cells, 93% red blood cells with the remaining 6% being platelets and plasma. Activated platelets release growth factors (healing proteins) which can be advantageous for wound healing and hair regrowth.
When platelets are caught in a blood clot, or have contact with a reactive agent, they begin to release growth factors. This causes the production of collagen and the blood vessels to form. White blood cells in the area gobble up bacteria that might cause an infection. Basically, cell growth and activity are stimulated, facilitating follicular rejuvenation.
Platelt Rich Plasma therapy is also used after hair transplant surgery to speed healing of the wounds and optimize new growth.
- About 30 to 60 cc of blood is drawn from the patient.
- The blood is put into a centrifuge (spun) to separate the PRP from the red blood cells.
- The top part of the patient’s scalp is cleaned and anesthetized.
- Multiple injections of PRP are given in the anesthetized area and massaged into the skin.
- Some practitioners use a “scalpuroller” instead of injections. The tool looks like a lint roller only instead of sticky strips there are very fine needles that aerate the scalp. Then, the PRP is massaged in.
- The treatment takes about one hour.
Some people have said that they did have some soreness after the procedure, but that the feeling did fade quickly. The great thing about this procedure is that there are no side effects. The new hair growth takes about 9 to 12 weeks for the normal hair growth phase to begin. Many patients will have one to three additional treatment around the eight-month intervals.
The benefits after PRP treatments have shown that people end up with stronger, thicker hair. PRP is not a miracle cure for hair loss. In some cases PRP has shown to be more effective in treating female hair loss.
PRP therapy has been growing, but some doctors are not in support of PRP as a primary hair loss therapy, some have come to recommending it after hair transplant procedure to promote faster healing.
