Does PRP help men and women with thinning hair?

PRP Therapy for Hair Growth

Platelet Rich Plasma (PRP) therapy was first used to regenerate or stimulate hair in 2009. It has gotten some good buzz but is still considered new and without guarantees. PRP utilizes growth factors in a patient’s own blood, which is drawn as part of the PRP procedure. The process is non-invasive, for many painless, and only the top of the scalp is anesthetized.

Why are platelets good for hair growth? Your blood consists of 1% white blood cells, 93% red blood cells; the remaining 6% are platelets and plasma. Activated platelets release growth factors, or healing proteins, which are advantageous for wound healing and hair regeneration.

When platelets are caught in a blood clot, or have contact with a reactive agent, they begin to release the growth factors. This causes the production of collagen to and blood vessels to form. The white blood cells in the area gobble up bacteria that might cause infection. In short, cell growth and activity are stimulated, facilitating follicular rejuvenation.

PRP is also used after hair transplant surgery to speed healing of the wounds and optimize new growth.

The Treatment

* About 30 to 60 cc of blood is drawn from the patient.

* The blood is centrifuged (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.

People report having a sore scalp following the procedure but that it fades quickly, and there are no known side effects. The new hair growth becomes noticeable in 9 to 12 weeks. Most patients have one to three treatments at around eight-month intervals.


Before and after treatment pictures of PRP patient have shown that people end up with stronger, thicker hair, but not a lot more. PRP is not a miracle cure for hair loss.  In some cases, PRP has been shown to be more effective in treating female hair loss.

The use of PRP for hair loss has grown since 2009. Even so, not all doctors are on board with PRP as a primary hair loss therapy. Some recommend using it only after a hair transplant procedure to promote healing or in junction with other hair loss treatments. PRP is currently used to treat wounds, promote healing after surgeries and arthritis treatment.
