Platelet Rich Plasma Therapy (PRP)

Platelet Rich Plasma (PRP) therapy uses an individual’s own blood that contains a higher than normal platelet concentration to promote healing of both hard and soft tissue. There are numerous uses for PRP including the promotion of hair growth, healing musculoskeletal injuries, and much more.

The high platelet concentration plasma contains numerous growth hormones and cytokines that cause your tissues to stimulate a mild inflammatory response. This ultimately results in increased blood flow, new cell growth, and tissue regeneration.

The Multi-Step PRP Treatment:

  1. A sample of blood will be collected from the patient (15-20mL)
  2. This blood sample is spun through a centrifuge to separate its components
  3. The plasma portion, or liquid portion of blood, is inundated with a high concentration of platelets (growth factors) during the centrifuging process
  4. PRP is extracted from the rest of the blood sample
  5. PRP is injected into the subcutaneous tissue of the scalp

What type of results has research shown?

While your provider will not be able to guarantee results, the following is a summary of research studies that have shown this procedure to be effective and the results experienced by their participants:

Cervelli, V., et al. “The effect of autologous activated platelet rich plasma (AA-PRP) injection on pattern hair loss: clinical and histomorphometric evaluation.” BioMed research international 2014 (2014). “At the end of the 3 cycles of treatment, the patients presented clinical improvement in the mean number of hairs, with a mean increase of 18.0 hairs in the target area, and a mean increase in total hair density of 27.7 ( number of hairs/cm2) compared with baseline values.”

Betsi, Evelyn-Evanthia, et al. “Platelet-rich plasma injection is effective and safe for the treatment of alopecia.” European Journal of Plastic Surgery 36.7 (2013): 407-412. “Before treatment, 90.5 % of our patients had a positive pull test with a mean number of eight hairs. After the third session, the pull test was negative in all patients with an average number of three hairs. Global pictures showed a significant improvement in hair volume and quality, which was confirmed by a high overall patient satisfaction. The results were even more obvious in patients who suffered from alopecia for less than 2 years.”

The PRP procedure is relatively new to the world of hair restoration. It’s become slightly mainstream in the past several years, but more large-scale studies are needed to prove it’s effectiveness. Both studies listed above have less than 50 participants in each study. Given that these participant sample sizes are less than ideal, PRP should be considered an additional (augmented) treatment to the already well-proven treatments that have been studied with large groups of individuals.
