Which is More Effective Hair Loss Treatment: Minoxidil (Rogaine) or Finasteride (Propecia)?

January 25th, 2007

Q: Will Propecia and Minoxidil reverse some of the miniaturization going on with someone with thinning hair? If I do need a hair transplant will I have to stay on these medications?

A: Yes, both minoxidil (Rogaine) and finasteride (Propecia, Proscar) affect the miniaturization of the hair follicles and help restore the shrunken follicles to cosmetically viable hair.

Minoxidil works by directly simulating miniaturized follicles to grow, whereas finasteride blocks DHT, the hormone that causes hair to miniaturize and eventually fall out.

Finasteride is much more effective than minoxidil in preventing or reversing the miniaturization process and it is so much more convenient to use that we generally suggest finasteride after a hair restoration procedure, but rarely recommend minoxidil.
