Can I use Proscar with Rogaine and/or Retin-A?
Yes. Proscar when used with Rogaine and/or Retin-A is much more effective than using Rogaine alone. Several people who have been long time users of Minoxidil 2% with little or no effect have reported almost an immediate start of hair growth after starting Proscar. Since Proscar works against the cause of hairloss, it allows Minoxidil to work better. This combination is the fastest way to get results.
