PRP for Hair Restoration
PRP has been in use for hair restoration for many years without solid evidence on its efficacy. The studies that show a positive result with PRP are often done with smaller cases and they have not shown any improvements in long term. There are some new studies that show similar effect to PRP with only infiltration of saline to scalp. Those usually show limited result temporarily. We have never offered nor recommended PRP as an option for hair restoration with hair transplant procedures or by itself. That will stay the same unless there will be better documentation on its use and long term results.
