Is that normal?
Usually PRP requires 4 treatments, done monthly, to yield great results.Consult with your doctor about follow up appointments for additional procedures.
Unfortunately PRP for hair loss has not been standardized and hair loss is multifactorial. While Acell as an ECM (extracellular matrix) is popular its not clear there is an adantage. Also, what type of PRP machine, how much, was it activated properly, did you also have microneedling, etc... In our office, we use Bio-d which is placental ECM with highly concentrated PRP and microneedle. This is the method shown to work by Dr. Alan Bauman, one of the worlds experts in hair loss.You should return to the office that did your prp for a hair check.Good luck!
