There is no uniformity when it comes to PRP therapy and no clinical trials standardizing PRP with Acell and Adipose tissue. Each doctor that performs this procedure uses the method, additives, and components of their choosing. What ultimately goes into the plasma and gets reinjected into the scalp is at the full discretion of the doctor. Because PRP therapy is a relatively new treatment and each treatment varies WIDELY from office to office, there isn't a lot of research out about the different combinations. What we do know, is that PRP is effective at promoting hair follicle strength, reversing recent hair loss, warding off hair loss, promoting healing in scar tissue, and promoting healing in hair transplants. Different components work differently on different patients. Most doctors use what components they find works best on their patients. Ultimately, the PRP treatment itself is the bulk of the efficacy of the treatment. The additives are just added benefit. Please keep in mind that not all PRP treatments are created equal, just as the components vary, so does the method of extracting, reinjecting, and the quality of the centrifuge. Make sure to do your research before committing to a series of treatments. In the web reference I have a video showing PRP + Acell + Adipose tissue via liposuction procedure from the abdomen.
