Yes, absolutely.  After your hair transplant, we will put you on what we feel is the best regimen to prevent further hair loss, including Rogaine, Laser Light therapy, Ketochonazole shampoo, and possibly Propecia, depending on your age and tolerability of that drug.  All these are meant to put your vellus hairs, which would but for this regimen fall out, in the best environment to grow.  Especially if you are still in the process of losing hair, you must be on a regimen to reduce further hair loss, or you’ll be back for another hair transplant, for sure.
