At Bernstein Medical we use the Emcyte Pure PRP System. This is a “double-centrifuge” technique that allows the active biologic factors of serum to be administered at the most effective concentration. This double processing is the only way that the optimal concentration of growth factors in PRP can be achieved.
If PRP hair loss therapy is appropriate, we can begin your treatment at the time of your consultation. After the initial session we will administer the next treatment at 6 weeks. Additional treatments are given at three month intervals for the first year and then every 6 months depending on the response.
The treatments are administered by a Bernstein Medical physician and take about a half hour to 45 minutes. For some patients, the injections may be uncomfortable. For those patients we offer local anesthesia prior to the injections which helps to reduce the discomfort. Patients are monitored photographically to assess the benefits of therapy. We will modify your treatment schedule based on your individual response to therapy. The physicians at Bernstein Medical have the knowledge to know when PRP for hair loss is appropriate and the skill to inject the proper quantity of PRP at just the right depth to achieve the desired result — a skill that cannot be overstated.
Before and After Photos of PRP Hair Loss Treatment
PRP Patient CMR before treatment (left) and 7 weeks after his second PRP session (right)
Patient CMR has had two PRP therapy sessions. The “after” photo was taken three months after his first treatment and seven weeks after his second treatment. The patient has been on finasteride for over 15 years.
PRP Patient CRZ before treatment (left) and 3 months after a third PRP treatment (right)
Patient CRZ presented to our office requesting platelet rich plasma (PRP) injections to his scalp. He is not taking finasteride. He underwent three PRP treatments to his crown. The second photo is approximately 5½ months following the initial PRP hair loss treatment, and 3 months following the third PRP treatment. He is demonstrating improvement in hair thickness in less than 6 months, and further improvement is expected.
PRP Patient YCA before treatment (left) and 6 weeks after a second PRP treatment (right)
Patient YCA (pictured above) presented to our office requesting platelet rich plasma (PRP) injections to his scalp. He has been taking finasteride 1.25 mg for over 5 years and he has recently noticed his hair thinning while still on the medication. He underwent two PRP treatments to his crown spaced 6 weeks apart. The second photo is approximately 3 months following the initial PRP treatment, and 6 weeks following the second PRP treatment.
PRP for Hair Loss
The Platelet Rich Plasma (PRP) commonly used in hair restoration is “autologous,” meaning that it is derived from the patient’s own blood. To obtain PRP, a patient’s blood is spun in a centrifuge to separate the solid from liquid components and platelet activators, such as thrombin, calcium chloride and sometimes collagen, are added. The separated “solid” portion of the blood is PRP (platelet rich plasma).
There are commercially available systems for PRP hair loss treatment. These include: Cydomedix, Emcyte Pure PRP, Angel system, and Harvest system. PRP is sometimes combined with A-Cell, although the benefit of this combination is speculative.
PRP is then placed into a syringe and reintroduced into the treatment site i.e., either the surgical site or an area of hair loss. PRP be can sprayed onto a recipient area during and after a hair transplant, laid into the donor incision, or injected directly into a balding scalp. Prior to injecting PRP, doctors often create a ring-block of local anesthesia with 1% lidocaine.
When used to stimulate hair growth most doctors schedule injections at intervals of 1 to 9 months. Some improvement (in reversing miniaturization) can be expected in the first 2-6 months. The treatments must be continued periodically to maintain any improvement.
Mechanism of Action
For the medical treatment of hair loss, practitioners use PRP to stimulate the growth of follicles, thereby reversing the hair miniaturization seen in androgenetic alopecia (common baldness).
It is conjectured that the introduction of platelets and white blood cells through platelet rich plasma (PRP) can amplify the body’s naturally-occurring wound healing mechanism. It is also proposed that PRP can actually stimulate the stem cells (dermal papilla) of the newly transplanted hair follicles. Other doctors feel that during a hair transplant procedure, the body’s normal production of bioactive growth factors are optimal for healing and subsequent growth and that PRP for hair loss gives no additional benefit.
What are the Indications for PRP for Hair Loss?
PRP is used in many areas of medicine, including the acceleration of healing of tendon injuries, the treatment of osteoarthritis, in some aspects of dental work (i.e. jaw reconstruction), and in cardiovascular medicine. The concentrated form of plasma has been shown to accelerate wound healing and tissue repair and, thus, could potentially benefit hair restoration procedures.
In hair transplantation, PRP can be injected into or sprayed on the recipient site area to, theoretically, stimulate the healing of the transplanted grafts and into the donor area to facilitate healing of the donor incision and potentially minimize scar formation.
In the medical treatment of male and female pattern baldness (androgenetic alopecia), PRP can be injected into the balding scalp to potentially stimulate thin (miniaturized) hair to grow into thicker (terminal) hairs. Patients with thinning, but not totally bald, areas would be the best candidates.
PRP for hair loss is a relatively new treatment with a limited number of scientific studies to show its efficacy. The long-term benefits of PRP treatments for hair loss are not yet known. All patients receiving PRP treatments at Bernstein Medical are followed closely to determine effectiveness and if other therapeutic modalities may be needed.
